Overview

Use filters to display a sub-set of data in a chart. When you create or edit a filter, PhixFlow displays a window where you can specify a set of clauses. Each clause contains a number of conditions.

...

You can name and save filters for future use, or use them temporarily. 

For information about other settings, see Form Descriptions.

Ignore Case

Insert excerpt
_check_box_untick
_check_box_untick
nopaneltrue
so that, for PhixFlow instances running on Oracle or MariaDB (MySQL), the condition only matches strings that have the same capitalisation (case-sensitive).

Insert excerpt
_check_box_ticked
_check_box_ticked
nopaneltrue
  so that the condition matches strings that have any capitalisation (case-insensitive). For example "abc" matches "abc", "Abc", "ABC", etc. For case-insensitive filters, there is no difference if the attribute is also indexed. 

Whether or not the check box is ticked by default depends on the underlying stream attribute property tab → Advanced section → Filter conditions are case-independent by default.

Note
This option affects the behaviour of filters for PhixFlow instances running on Oracle or MariaDB (MySQL) databases.
For PhixFlow instances running on a SQLServer database, filters are always case-independent.

Some Filter Examples

Create prompt filter

You can create a filter that will prompt users to enter a value, and filter based on that. For example, if you have data which contains people's names, you could create a filter like:

Name contains _prompt.EnterName fx

Filter on Current User

If your data contains details of the user, you may be able to filter based on the currently logged in user. For example, to set a filter where the owner equals the current logged in user, add a condition to the filter:

Owner equals _user.name fx

Enter a list of values for an "Is In" or "Is Not In" filter

If you want to select a set of records which have a field set to one of a range of possible values you can do this by selecting the "Is in" or "Is not in" comparator from the drop down list and then simply typing the list of values into the edit box to the right of the comparator as a comma separated list like this:

...

Country Is in ["England","France","Germany"] fx

Using Filter Pickers

If the stream view that you are filtering on has Allow Filter Picker selected, then PhixFlow displays the  icon after the value field. To use a filter picker:
