Last MARK not showing in a line series

[Wieselberg]

After upgrading to ActiveX 2011 we do not see the lst MARK in a line series. The datapoint is active, so we can view tooltips even for that point, but the mark is missing. Here is some client-side code we have dealing with marks and the image below it.

function changeMark(theSIndex,SeriesIndex) {
var theX
var theY
var adjustedIndex

// Adjust from index to value
adjustedIndex = parseInt(theSIndex) + 1;

// Add Annotation tool to chart
if (dpToolFlag == false) {
Chart1.Tools.Add(10);
dpToolFlag = true;
}

//dpToolItemNumber = numTools + 1;
dpToolItemNumber = Chart1.Tools.Count - 1;
if(dpToolItemNumber < 0)
dpToolItemNumber = 0;
numTools = dpToolItemNumber - 1;
Chart1.Tools.Items(dpToolItemNumber).asAnnotation.Shape.CustomPosition = 1;

// Calulate X pos and Y pos from index
theX = Chart1.Series(SeriesIndex).CalcXPos(theSIndex);
theY = Chart1.Series(SeriesIndex).CalcYPos(theSIndex);

// Set position of annotation based on X and Y values
Chart1.Tools.Items(dpToolItemNumber).asAnnotation.Shape.Left = theX;
Chart1.Tools.Items(dpToolItemNumber).asAnnotation.Shape.Top = theY;

// Set the string that will appear in annotation
Chart1.Tools.Items(dpToolItemNumber).asAnnotation.Text = "Point: " + adjustedIndex;

}

I did some further testing on this. This problem seems to only happen on wide-screen monitors. Standard width monitors show the mark properly. This also only happens with ActiveX. If an image file is loaded then the mark appears at the last point.

Hi Wieselberg,

Are you using the latest version available?
http://www.teechart.net/support/viewtop ... =1&t=12950

The following code seems to work fine with it:

Code: Select all

Private Sub Form_Load()  
  TChart1.Aspect.View3D = False
  
  TChart1.AddSeries scPoint
  TChart1.Series(0).FillSampleValues
End Sub

I was not using maintenance release 5 at the time. I had 4 for the test. Is there a known issue that you resolved with 5?

Hi Wieselberg,

Yes, take a look at this thread (note TeeChart AX is a wrapper from the VCL version so the changes applied to the first also affect the second)

Maintenance release 5 appears to have fixed this issue. Thank you very much!
