Help with Map Series data

Hi!

What is the basic configuration process to fill the Map values?
For example, I add a 'Spain' Series to the TChart component in desingtime.
Then, at runtime, I want to fill or modify the values of each state or poligon. How can I do it?

I have been trying it either manually and using a DataSource but I can't get it to work

Hi santycg,

You can access the shapes using either its index or name, for example:

Code: Select all

  Series1.Shapes[0].Color:=clRed;
  Series1.Shapes.ByName['Girona'].Color:=clLime;

Perfect!

BTW... Is it possible to hide the Marks with "0"/empty value?

Some poligons have no value/data and I don't want to show the Mark of that poligons.

Hi santycg,

You can use OnGetMarkText event and set to an empty string those marks you don't want to be visible.
