not showing selected points

kualoa1 · Post by **kualoa1** » Thu Dec 04, 2008 11:15 am

In a delphi app, I have a set of line series that have up to 32 x values. sometimes only the first 18 have values. If I load (Series1line.add(x,qtr);) the x values only up to 18, it auto adjusts (widens) the x interval size. what setting controls the x interval width; how to get the line series not to show points/line after 18 in the example case?

Thank you.

Hi kualoa1,

You could try using bottom axis SetMinMax method as described in Tutorial 4 - Axis Control. Tutorials can be found at TeeChart's program group.

this works, but the leftaxis now needs to be at a fixed position.

to set this I used chart2.LeftAxis.IStartPos:=100; but it seems to have no impact. is another setting required? is the istartpos valued in pixels?

thank you.

Hi kualoa1,

I'm sorry but I don't understand what are you trying to do here. Could you please give us some more details or send us an image so that we can see which is your problem?

I uploaded this file graphic.png

I seek to set the left axis in the same position for each chart and have the intervals for each x item match.

what setting is required?

thank you.

Hi kualoa1,

Thanks for your file. In that case you can do something like this:

Code: Select all

			tChart1.Draw();
			tChart2.Draw();			
			tChart1.Axes.Left.SetMinMax(Math.Min(tChart1.Axes.Left.Minimum, tChart2.Axes.Left.Minimum), 
																	Math.Max(tChart1.Axes.Left.Maximum, tChart2.Axes.Left.Maximum));
			tChart2.Axes.Left.SetMinMax(tChart1.Axes.Left.Minimum, tChart1.Axes.Left.Maximum);

Hope this helps!

Hi kualoa1,

how to set left axis (the vertical bar) start draw 100px from left margin?

You can do this:

Code: Select all

  Chart1.Axes.Left.PositionUnits:=muPixels;
  Chart1.Axes.Left.PositionPercent:=100;

If the problem persists please send us a simple example project we can run "as-is" to reproduce the problem here.

have uploaded the resulting view. I want he left axis -- the vertical bar -- (and remainder of chart area) to start at the same place and be the same width. the sample graphic has the vertical bar embedded in the chart.

how to set the offset at 200px?

Ok, in that case you can do something as told here.

  Chart1.Axes.Left.PositionUnits:=muPixels;
  Chart1.Axes.Left.PositionPercent:=200;

I used this

Code: Select all

  With Chart2 do
  begin
    Left := 120;
    Width := 650;
    //Margins.Left := 0;
    Axes.Left.TitleSize := 15;
    Axes.Left.LabelsSize := 30;
    Axes.Left.LabelsAlign := alDefault;
  end;

and got results in upploaded graphic. does not appear left 120 is working as hoped. margins.left raised an error.

how to move over to right further?

thank you
