| Field | Description | ||||
|---|---|---|---|---|---|
| Basic Settings | |||||
| Name | The name of the stream view. By default, a space will be included before each capital letter. For example, the name CustSpendAverage will be displayed in the column heading as Cust Spend Average. | ||||
| Display Type | A number of chart types are available:
HELPDEVTODO: no file download button on form; is this still correct anyway? If display type is a chart and the user elects to output the chart to HTML (either via a File Exporter or from a chart, PhixFlow will output the chart to HTML as a picture (.PNG). | ||||
| Default Sort Order | If specified, the default order in which data should be displayed. See the Stream View Sort Order form. | ||||
| Default Filter | Any filter on the stream can be selected as the default filter for this view. | ||||
| Default Action | The action that will be applied when users double-click on a row in a data grid. Often this is an update action - that allows users (if they have permissions to run the action) to update the record. But you can make this open a read-only detailed view of the record if that is more useful for most users. See Action. | ||||
| Form View | Tick this box to make this a form view. This can be used to accepting input from a user, for an insert or update action. | ||||
| View Attributes | |||||
A list of attributes displayed in the view, or to build a chart. Press For each attribute, the following fields are shown: | |||||
| Order | The order in which the attributes will appear in the view. For a grid view, this is the order of columns. | ||||
| Name | The display name of the attribute in the view. By default, this is the same as the name of the attribute in the underlying stream. Remember that if you are applying an Aggregate Function to the attribute, it is often useful to reflect that in the display name. For example: you are going to display the average monthly spend for each customer, by applying the aggregate function Average to the attribute | ||||
| Stream Function | You can specify an Aggregate Function on this attribute. As soon as you have specified a single aggregate attribute in your view, any other fields will be either aggregate attributes - if you also specify an aggregate function for them - or used as grouping attributes. | ||||
| Role | This setting only shows if the view is a chart, i.e. not a data grid. This is the role that the field has in generating the chart. HELPDEVTODO: are there fairly generic descriptions for roles that are worth putting in, or is it only worth describing these in context for each chart type? | ||||
| Decimal Places | This field will only show if the underlying stream attribute has type Float. The number of decimal places to display. | ||||
| Date/Time Format | This field will only show if the underlying stream attribute has type Date or Datetime. See toString for a description of display formats. | ||||
| Hidden | HELPDEVTODO: not shown for charts, should it be? If not, put in Grid Settings section Whether the field is shown on the view. Sometimes you need to include fields in views so that they can be used in filters and Actions, but displaying them would make the view cluttered. Make the field hidden. | ||||
| Stream Attribute Details | |||||
Name | The name of the underlying stream attribute. | ||||
| Type | The type of the underlying stream attribute. This cannot be edited here. It must be edited in the Stream. | ||||
| Grid Settings | |||||
| These settings are only available for view attributes for grid views | |||||
| Grid Default Width (pixels) | Set the default width of the column for this attribute. PhixFlow will create the grid with default column widths - you only need to specify a value in this field if the width you want is different from this default. | ||||
| Label | An optional label for the resulting column header. If left blank, this is the Name of the stream view attribute. The label gives you more options for setting the column header - for example, control over the white space in the column heading - but you can also make this an expression. For example, to that the column contains transactions for the currently logged in user, you could use:
For user
To use an expression in this field, tick the box Label is Expression | ||||
| Label is Expression | Tick this box if you want to set the Label using an expression. | ||||
| Changes Row Colour | If ticked, the row colour changes whenever the value in this field changes. | ||||
| Alignment | Set the alignment of values in this column to:
| ||||
| Formatting Rules | |||||
A list of the formatting rules that apply to this field in the view. For each formatting rule, set the following fields: | Rule Expression | ||||
| Style | Select a style from the drop-down list, or create a new style. | ||||
| Order | The order in which the formatting rules are applied. | Enabled | Stop if True | ||
| Excel Template | An excel template can be linked to the view to specify the format the chart data should be exported in. The location that excel templates must be saved to is specified in the System Configuration. | ||||
| Number of Periods | Number of processing periods from the stream to display on the chart. If a full set of data is generated in each period, then this will be 1. If the data is spread across processing periods in the stream - for example, each processing period only contains new data for that day, but we want to plot data across a number of days - then this number must be high enough to include all data of interest to show on a chart. | ||||
| Background Filter | Any filter on the stream can be selected as the background filter for this view. When the user opens this view the background filter is applied first and any other filter applied to the view (either specifically created/selected by the user or automatically applied as the default filter described above) acts in addition to the background filter. | ||||
| All Users Can View Data | If checked, this specifies that all users can view this stream view by default (provided they have the basic privilege to view stream views). If this field is not checked, then access to the stream view is controlled by dropping user groups onto the stream's "User Groups" tab. | ||||
| Default Width | The default width of the Stream View. If empty, the View's width will be set to the system default value. | ||||
| Default Height | The default height of the Stream View. If empty, the View's height will be set to the system default value. | ||||
| Form View | Check box to determine if this view is to be used as a Form View. When a user is entering or updating data using a form view, you can use the internal variable _form to use a value already entered in the form in the filter on a selection view. That is, the values that appear in a drop down list will be governed by values they have entered so far in the form. See selection view attributes for details of using selection views to create drop down lists. | ||||
HELPDEVTODO not yet in form Height On Form (pixels) | This only applies on Form views: sets the height of the form field for this attribute. PhixFlow will create the form field with a default height - you only need to specify a value in this field if the height you want is different from this default. | ||||
HELPDEVTODO not yet in form Width On Form (pixels) | This only applies on Form views: sets the width of the form field for this attribute. PhixFlow will create the form field with a default width - you only need to specify a value in this field if the width you want is different from this default. | ||||
HELPDEVTODO not yet in form Multiline on Form | This tick box will only be shown when configuring a view attribute on a Form view. If ticked, users can press the Enter key to create multiple lines in this field, or copy multi-line text into this field. | ||||
Values governing the appearance of charts are configured in the Chart Layout tab.
The following fields apply to Pivot views:
| Field | Description | ||||
|---|---|---|---|---|---|
| Pivot Column Source | The pivot column source determines how the the values that are converted to Pivot Columns are generated:
If no labels are provided, they are derived from the pivot values using the formatting options set on the Column attribute. | ||||
| Pivot Column Expr | Form Settings | ||||
| These settings are only available for form views - that is, grid views that have Form View ticked. | |||||
| Read Only | This makes the field read-only in the form view. | ||||
| Height On Form (pixels) | Sets the height of the form field for this attribute. PhixFlow will create the form field with a default height - you only need to specify a value in this field if the height you want is different from this default. | ||||
| Width On Form (pixels) | Sets the width of the form field for this attribute. PhixFlow will create the form field with a default width - you only need to specify a value in this field if the width you want is different from this default. | ||||
| Multiline on Form | If ticked, users can press the Enter key to create multiple lines in this field, or copy multi-line text into this field. | ||||
| Selection View Attribute | This sets the dropdown list from which the user can pick a value. Drag the stream view attribute that you want to use for the dropdown list into this field. The Show the dropdown button option must be ticked to display the drop down. When a user is entering or updating data using a form view, you can use the internal variable _form to use a value already entered in the form in the filter on a selection view. That is, the values that appear in a drop down list will be governed by values they have entered so far in the form. See Configuring Selection View Attributes below for an example of configuring selection view attributes. If another stream view attribute has a Selection View Attribute set and has Show the dropdown button set to yes, then it is possible to set the current stream view attribute from the same selection view without a further dropdown list. Drag the stream view attribute that you want to use to set this stream view attribute into this field Drag the attribute out of the field to delete the contents of the Selection View Attribute. | ||||
| Show the dropdown button | See Selection View Attribute above. | ||||
| Formatting Rules | |||||
A list of the formatting rules that apply to this field in the view. For each formatting rule, set the following fields: | |||||
| Rule Expression | |||||
| Style | Select a style from the drop-down list, or create a new style. | ||||
| Order | The order in which the formatting rules are applied. | ||||
| Enabled | |||||
| Stop if True | |||||
| Excel Template | An excel template can be linked to the view to specify the format the chart data should be exported in. The location that excel templates must be saved to is specified in the System Configuration. | ||||
| Number of Periods | Number of processing periods from the stream to display on the chart. If a full set of data is generated in each period, then this will be 1. If the data is spread across processing periods in the stream - for example, each processing period only contains new data for that day, but we want to plot data across a number of days - then this number must be high enough to include all data of interest to show on a chart. | ||||
| Background Filter | Any filter on the stream can be selected as the background filter for this view. When the user opens this view the background filter is applied first and any other filter applied to the view (either specifically created/selected by the user or automatically applied as the default filter described above) acts in addition to the background filter. | ||||
| All Users Can View Data | If checked, this specifies that all users can view this stream view by default (provided they have the basic privilege to view stream views). If this field is not checked, then access to the stream view is controlled by dropping user groups onto the stream's "User Groups" tab. | ||||
| Default Width | The default width of the Stream View. If empty, the View's width will be set to the system default value. | ||||
| Default Height | The default height of the Stream View. If empty, the View's height will be set to the system default value. | ||||
Values governing the appearance of charts are configured in the Chart Layout tab.
The following fields apply to Pivot views:
| Field | Description | ||||
|---|---|---|---|---|---|
| Pivot Column Source | The pivot column source determines how the the values that are converted to Pivot Columns are generated:
If no labels are provided, they are derived from the pivot values using the formatting options set on the Column attribute. | ||||
| Row Attributes | The row attributes will be displayed on the left of the view. | ||||
| Maximum Pivot Columns | This is the maximum number of pivot columns that can be displayed. If this is blank, the system-wide default in System Configuration is used. | ||||
Column attribute | Values in the Column Attribute are mapped to separate columns in the resulting view. The formatting options on the attribute (decimal places, date/time format) can be used to automatically generate column headers corresponding to Column Attribute values. | ||||
| Value Attribute | When the view is displayed, the value in this Value Attribute will be displayed in the column corresponding to the value in the Column Attribute. A Pivot View is not automatically grouped. To make this a grouped view, you should set the value attribute's aggregate function (e.g. to SUM). | ||||
| Label Attribute | If Pivot Column Source == View Data, this attribute provides the pivot column labels corresponding to the column values. In most cases, the number of values for the label attribute, should be exactly the same as the number of values for the column attribute. |
The following fields apply to all graphs, that is, all display types other than Grid or Pivot:
| Field | Description | |
|---|---|---|
| Default Resolution | Set the default resolution for the generated graph. Larger values will produce a more finely grained image, and equivalently smaller fonts, sometimes useful when using graphs containing a large amount of data. Smaller values will produce a bolder, less finely grained image, sometimes useful for producing a clearer graph when there is not much data to display. | |
| Minimum Value | Minimum value along the vertical axis to be displayed. This value will be lowest point on the vertical axis if any value in the data plotted falls below this value. Otherwise, the graph will be automatically sized as normal. | |
| Maximum Value | Maximum value along the vertical axis to be displayed. This value will be the highest point on the vertical axis if any value in the data plotted falls above this value. Otherwise, the graph will be automatically sized as normal. | |
| Fixed Scale | If fixed scale is turned on, the the maximum value and minimum value defined will always be used as the highest and lowest points on the vertical axis, regardless of the data plotted. | |
| Horizontal Axis Title | The label given to the horizontal axis. | |
| Vertical Axis Title | The label given to the vertical axis. | |
| Include Legend | When a series is used, if this is turned on then a box listing all lines shown, along with the corresponding values, is displayed on the graph. | |
| Tick label angle | The orientation of the values displayed along the horizontal axis. Select a Pivot Column Expr | If Pivot Column Source == Expression, this expression must return either a list of values or a list of pairs of values (the values and corresponding labels). E.g.
or
The expression can refer to any lookup pipe that is an input to the Stream being viewed. If no labels are provided, they are derived from the pivot values using the formatting options set on the Column attribute. |
| Row Attributes | The row attributes will be displayed on the left of the view. | |
| Maximum Pivot Columns | This is the maximum number of pivot columns that can be displayed. If this is blank, the system-wide default in System Configuration is used. | |
Column attribute | Values in the Column Attribute are mapped to separate columns in the resulting view. The formatting options on the attribute (decimal places, date/time format) can be used to automatically generate column headers corresponding to Column Attribute values. | |
| Value Attribute | When the view is displayed, the value in this Value Attribute will be displayed in the column corresponding to the value in the Column Attribute. A Pivot View is not automatically grouped. To make this a grouped view, you should set the value attribute's aggregate function (e.g. to SUM). | |
| Label Attribute | If Pivot Column Source == View Data, this attribute provides the pivot column labels corresponding to the column values. In most cases, the number of values for the label attribute, should be exactly the same as the number of values for the column attribute. |

HELPDEVTODO - update screen shots and instructions as needed
Configuring Selection View Attributes is illustrated with an example:
You have a selection of items for sale, as below:
You also have a form view that allows you to edit these entries - this pops up when the Edit button is clicked:
You need to assign a tax band to each item. You also have a set of tax bands configured:
To help with this task, you will set up a selection list to populate the tax band and tax rate values for the sales items, from the list of tax bands. To do this, open the configuration form for the form view 008 Edit Sales Item, then open the configuration form for the view attribute TaxBand:
Then open the list of attributes for the view that gives the list of tax bands:
From the list of attributes that pop up, drag the attribute BandDescription into the Selection View Attribute field, and tick the Show the dropdown button flag.
Populating further attributes from the same selection view
Repeat the same process for the view attribute TaxRate, dragging the attribute BandRate from the view of tax bands into the Selection View Attribute field. This time, do not tick the Show the dropdown button flag.
The form view will now appear as:
If you press the button next to the TaxBand field the list of tax bands will appear - you can select a row from this list by double-clicking it. This will populate the TaxBand and TaxRate fields for the sales item with the selected tax band details:
Controlling drop-down lists with other form values
You can use values that users have already entered into a form to control the values that appear in a drop down list. This is done by using the internal variable _form. Add a background filter on the view used in the selection view attribute, and include a clause which uses the value _form.formAttributeName to match values in the selection view with the value entered by the user in the attribute formAttributeName.
Model Ref: 008

The form provides the standard form icons.
