Use this method to draw layer charts direcly. Normally charts are drawn upon paint process.

Using charts, we can make simple statistics by adding numbers to the charts' values property, e.g., a simple legend of population density for a given area.

When using this operation, never call any function which uses FindFirst..FindNext (any function which iterates through the shapes using it). So never use inside an operation like Locate etc.
