This page is for data modellers who want to display data on a screen in a pie chart.
Overview
PhixFlow can display any Table data as a pie chart on GUI screens. This page will show you how to add data as a pie chart to any screen. It will go through a worked example of creating a pie chart of companies and their various industry sectors.
Creating a Company Industry Pie Chart
Once you have a screen it is simple to add any data to it. To add a Pie Chart:
- Click List Tables
- Drag and drop the desired table onto the screen. In this instance, the Contacts table is dragged onto the screen.
- PhixFlow then asks how to display the data using:
- Click Pie Chart.
- The attribute picker will then appear. Drag Industry to Label Attribute and Count() to Data Attribute. This is counting the number of companies per industry.
Relational attributes
For more information on adding relational attributes, see Creating a Grid.
Filtering - Potentially add this to its own page and reference it here and in the grid page
The data in displayed on the pie chart can be filtered in the following ways
Filter | Location | Link | Reason to use |
---|---|---|---|
Default Filter | View Editor | Filter | Default filters can be cleared by the user on the front end. Use a default filter when users are allowed to remove the filter to view all the data. If a default filter has been applied pie charts are marked with will remove the default filter. . Clicking on this icon and selecting Clear Applied FilterE.g. A pie chart displaying a list of companies has an Active boolean attribute. The default filter only displays active companies, but a user can clear this filter at any time to view all companies. |
Background Filter | View Editor | Filter | Background filters cannot be cleared by the user on the front end. Use a background filter to always filter any instance of the view by the parameters provided. Views can be reused by multiple data components. Using a background filter will filter all components which are backed by this view. |
Background Filter Rules | Grid Component Editor | Filter Rule | Background filter rules cannot be cleared by the user on the front end. They appear on the data component instead of the backing view so only applies to that component. Rules can be added to each filter to only apply in certain contexts. E.g. A button is clicked to show the data for a selected number of companies. The background filter only applies when companies are selected in another view using the expression countElements(CompanyList) > 0 |
Styles and Formatting - As above to avoid repetition.
Pie charts can be styled and formatted on the backing view. For more information see View. We may wish to make reference to colour maps here also.
Style | Location | Description and use cases |
---|---|---|
Change pie chart colours using Colour Map | Backing View > Chart Layout Can be used to assign colours to particular values. | See Colour Map |
Change Number Formats | Backing View > Chart Layout. |
|
Change Chart Styles | Backing View > Styles Tab |
