Before creating a thematic map of points, we first need a map layer with points.
Click on the button Add New Layer.
Follow the steps in the Add Data Tutorial to learn how to add a map layer with points.
After adding a map layer with points, click the Create Thematic Map button.
A window will appear which will aks for which layer you would like to create a thematic layer.
Select ‘Existing Layer’ and select the layer you would like to use in the box after ‘Current layer:’
Next are the Thematic Options. Here you can choose the thematic type. The first three options, Individual Colors, Range Colors and Range Sizes, will result in thematic points. You need to select a column as well. This is the column that will be used to calculate the thematic color/size on the map.
At Individual Colors the colors are added to the points related to the cell text. E.g. Customer or Prospect. Each value will get a different color, points with the same value will get the same color.
At Range Colors the point on the map will be colored related to the value mentioned in the cell. The range of values will be divided into 5 equal categories, with each categorie having its own color.
At Range Sizes the point on the map will have a size related to the value mentioned in the cell. The range of values will be divided into 5 equal categories, with each categorie having its own size.
Condition is the availability of a column with numbers to be selected.
Selecting the Range Colors option, will give you a result which looks like the image below.
