Odd X-axis

);

I have a chart with two series of XY-markers. The X-axis looks odd. I would like to have numbers like 10, 20, 30 etc on the axis and not values in between. Also there is a second row with values that don;t make any sense at all. The max value on the X-axis is 100. Code is listed below the chart.

   Chart.BeginUpdate;
   with Chart.Panes[0] do
   begin
      Series.Clear;
      Title.Font.Color := clBlue;
      Title.Font.Style := [fsBold];
      Range.RangeFrom := 0;
      Range.RangeTo := 100;
      Title.Text := '';
      XAxis.AutoSize := False;
      YAxis.AutoSize := False;
   end;
   // first serie
   with Chart.Panes[0].Series.Add do

	Hi, The secondary values are the XValues, please turn them off with XValues := False on Series X-Axis level. Additionally, the jumps between the values are caused by the MajorUnit and MinorUnit properties, you can set these also at Series X-Axis level. There is an option to turn off auto-calculation of units with the AutoUnits property.

	Bingo. Thanks a lot Pieter. I have now moved all my charts from a certain package to AdvCharts. I am quite satisfied with the flexibility and aesthetic aspects of the package. Regards, Stephan
