TChartSeries.ColorSource
TChartSeries
property ColorSource: String;
Unit
TeEngine
Description
This property is only used when connecting a Series to a database dataset or TChartSeries.DataSource.
The ColorSource property must be a valid numeric Data Field Name.
When loading the dataset records, a TDBChart component assigns every point's color to the ColorSource field value.
Color Values in Table or Query fields must be expressed as RGB values (integer).
Example:
Supose you have a table with the following fields: Color, Value, Text
Then you link the Series to this table:
with Series1 do
begin
YValues.ValueSource := 'Value';
XLabelsSource := 'Text';
ColorSource:='Color';
DataSource := Table1;
end;
For each record in Table1, a point will be added to Series1 using the fields Color, Value and Text.
