Thematic analyses allow you to present visually any information stored in a column of your data, via size color variation, size variation or else. You can create multiple thematic analyses in one or multiple slides to combine and create complex data visualization. Thematic analyses are saved in your map slides.
To add a new thematic analysis, click on the three dots of the slide action menu in the top bar of your map (1), then click “Create a new thematic analysis” (2).
This will open the thematic analysis creation dialogue, where you can :
Choose a layer: this is the layer your thematic analysis will be created on. The available layers are the layers you’ve added to your map.
Select column(s): this is the information which will be represented visually on the map. You can select multiple numeric columns.
Choose a representation: choose how you want to represent the column information. The type of representation depends on the type of your layer (polygon, polyline, points) and the type of the selected column(s) (numeric or string). See the section on types of thematic analysis below.
Click on “Add” once you have selected your layer, column(s) and representation. This will create the thematic analysis and add it to your map. You will see the effect of the thematic analysis in your map and in the legend, where you can customize it. A chart is also added automatically in the chart panel to reflect your thematic analysis. The column(s) used in the thematic analysis are also added to the table view and in the data tip.
You can also add a thematic analysis from the properties of a layer:
In this case the layer will be pre-selected in the thematic analysis creation dialogue.
When your thematic analysis has been created, you enter the slide edit mode automatically. You can see it with the green outer line that shows you what will be saved in the slide, with the save menu and with the green slide button.
After having customized your thematic analysis via the legend settings, click on “Save” or on the green slide button to save your changes. Please note that all other slide elements will be saved: map extent, panel layout, story, and table view columns.
You can stack multiple thematic analyses on the same layer to create advanced data visualization and show different information on your data on the same view: color, size and symbol (or patterns) can be stacked.
You can use size and color to represent different information.
Or you can combine different ways of presenting one information to highlight it:
Some thematic analyses cannot be stacked: if there is already a thematic analysis by color on your layer, creating another one will replace it. To avoid this, you can create a second slide to create your second thematic analysis. Your end users will be able to navigate from one slide to another and see the different color thematic analyses.
