How to override the shape order of the Scatter plot
If you have various categories in your Scatter plot, you can set different shapes for each of them.
To do this:
Depending on the order of your categories in the Data tab, these shapes will be divided accordingly. In other words, Europe will be represented by a circle, Asia by a cross, Africa by a diamond, and so on.
However, please note that if you have more than 7 categories, the shapes will eventually start repeating.
