Hi,

You can modify your values directly in the database, before loading the values to the chart.
Or you can load the values to the chart and then loop the Series YValues array to modify them.

Hi Yeray,

just tested this code, seems it is what i'm looking for.

DBChart1.Visible := false;
Series1.Active := false;
Series1.XLabelsSource := 'abc';
Series1.YValues.ValueSource := 'abc';
Series1.Active := true;
DBChart1.Visible := true;

regards
