Happy #MapInfoMonday,
Today's post is a quick one. I will in a short article present how you quickly can apply a ranged theme to a layer using a new feature added to
the WindowHelper tool.
First, you need to install the WindowHelper from the MapInfo Marketplace. You can access the MapInfo Marketplace from the Home tab. It's located as one of the last controls on the tab. Once you have opened the MapInfo Marketplace, look for the
WindowHelper tool, and use the Install button to download and install the tool. Now you are ready to use the additional capabilities this tool adds to MapInfo Pro.
Using Quick Ranged Theme
Right-click on the layer on which you want to create a ranged thematic layer and from the context menu select
Quick Ranged Theme....
In the dialog Quick Ranged Theme, the layer has been preselected in the list. You only have to select one of the numeric columns listed in the
Select Column for Thematic Map list and select a color range from the
Select Color Range list.
The color range Red that I have selected allows you to set the number of ranges using the
# of Ranges list
Some of the color ranges have a predefined number of ranges that you can't change from the start. You can however change this afterward which I will address later. That is for example the case for all the ColorBrewer color ranges
Now click
OK to create and see your ranged thematic map. That was quick, eh?
Modifying your thematic layer
We introduced
Interactive Thematic back in MapInfo Pro v17.0. This allows you to quickly modify an existing thematic map with a few clicks using the
Theme tab. The
Theme tab appears when you select a thematic layer in the
Layer List.
From the Theme tab, you can change all the settings that control your thematic layer. You can change the field or expression used for the thematic layer, you can change the number of ranges and the calculation method, and from the Color Palettes dropdown you can with a single click switch to a different color palette.
I hope you like this new way to quickly create a ranged thematic map. I might add other thematic layer types such a Individual if I see requests for them. Do let me know if that's something you'd like to see in WindowHelper moving forward.
Enjoy the rest of your #MapInfoMonday!
