Env.: TeeChart Pro 7.0.0.2 (Same problem with 7.0.0.6)

Hi All,

I'm displaying TeeChart in an HTML page but get a odd behaviour with zoom:

- Zoom doesn't work even though it is enabled (I added init for most/all zoom properties in despair. See init code below. My initial code only add Chart.Zoom.Enable= true)

- After I open the TeeChartEditor and close it (no action in there), zoom works ! (editor opened unsing <a href="javascript:document.all.Chart.ShowEditor();">

How come ?

Thanks in advance for your help.


----- Chart Init code : ------
<script language="javascript" type="text/javascript">
function RGB(red, green, blue) { return red+green*255+blue*65536; }

// Set title
var Chart= document.all.Chart;
Chart.Header.Text.Clear();
Chart.Header.Text.Add("History");

// Set general appearance
Chart.Aspect.View3D= false; // 2D
Chart.Panel.BevelInner= 0; // 0= None
Chart.Panel.BevelOuter= 0; // 0= None
Chart.Zoom.Enable= true;
Chart.Zoom.Direction= 2; // 2= tzdBoth
Chart.Zoom.Animated= false;
Chart.Zoom.MinimumPixels= 16;
Chart.Zoom.MouseButton= 1; // mbLeft
Chart.Zoom.Pen.Color= RGB(0,0,0);
Chart.Zoom.Pen.Width= 5;

// Add Series
Chart.RemoveAllSeries();
var nSeries= Chart.AddSeries(0); // 0 = scLine
Chart.Series(0).XValues.DateTime= true; // Time series
Chart.Series(0).Title="MyTag";
Chart.Axis.Left.Title.Caption="MyTag - Description";

Chart.Series(0).FillSampleValues(200);
</script>

OK, found the note in the docs about the manadatory OnAfterDraw handler().

Problem solved.

hi.
you can add next code in your sript
in addition, it's not useful to redifine the function RGB(),do you know in javascirpt language,it is a system funciton.
