Theme

Shows the distribution of features by a theme attribute, as a pie chart.

In this post, we will explore the Theme Chart, a powerful visual tool that allows you to visualize the distribution of features based on a specified theme attribute in a pie chart format.

Why using a Theme chart?

The Theme chart simplifies data exploration and aids in analyzing feature distributions by using customized colors. It is possible to match your map view styling with a theme chart.

Another advantage of using a theme chart is, that you can create multiple charts in one widget, which are selectable through a dropdown list.

Creating a Theme Chart

To begin, navigate to the widget menu and select Theme from the list of Graph Widgets.

The Theme widget configuration dialog on the General tab, showing the dataset, field name and classification settings.

Configuring your chart

Once you're in the theme configuration menu, set up your chart preferences.

Customize the chart name by clicking on My New Chart at the top of the modal.
Choose your dataset and the specific field you want to display.
Select the classification criteria that best suits your needs.
Select the number of groups you wish to include in the chart.
Decide whether you want to hide null or empty values.
Decide whether you want to enable sorting or not.

When your widget is created, you can add a second chart within your theme widget. Just click on the plus icon and configure your chart again.
