Hi Narcis,
Thanks for the response.
Since i am working on a web application ImageList control is not available here to point a particular index to get an image. Please note that I am using VS2005 and C#. Please suggest the needful.

Hi Ashutosh,

In that case you can try using a System.Web.UI.WebControls.Image availble in Visual Studio's toolbox.

Hi Narcis,
Still in dialema how to assign image to the series where the method 'AssignImage' accepts only integer value in.
TChart1.Series(2).asImagePoint.ImagePoint.AssignImage().
Not sure how to assign a image value to it. If you see its definition : void AssignImage(int ImageHandle); It asks for an integer value as parameter. below is the code where i am trying to assign the image value and getting the following error:
TChart1.AddSeries(TeeChart.ESeriesClass.scLine);
TChart1.AddSeries(TeeChart.ESeriesClass.scLine);
TChart1.AddSeries(TeeChart.ESeriesClass.scImagePoint);
TChart1.Series(2).asImagePoint.ImagePoint.AssignImage(Img1);//Image control with the new image
Error:
Argument '1': cannot convert from 'System.Web.UI.WebControls.Image' to 'int'
Please help.

Regards
Ashutosh

Hi Ashutosh,

I'm afraid this is not going to be possible to do by using the AssignImage method, as we're not able to get the handle (as integer) of the image.
So , the only way around would be to save the image as a file and then load it into the Series pointer :
axTChart1.Series(0).asImagePoint.ImagePoint.LoadImage(pictureBox1.Image.Save("c:\\temp\\image.bmp"));

Hi Narcis,
Still struggling to change the imagepoint's default image. I have few other issues also on which I need your help:
1)How could I get the x,y coordinates of a series on mouse move on the chart.
2)I need the X axis value of the chart in datetime format as is being dispalyed on the axis label.
Since i am using the activex control so all the codes should be javascript/vbscript only.
Any refrence or sample code compatible for actives control would work.
Regards
Ashutosh

Hi Ashutosh,

1)How could I get the x,y coordinates of a series on mouse move on the chart.

You should use TeeChart's OnMouseMove event and use given X and Y arguments for calling series' Clicked method as shown here. Then you could retrieve series values like this:

Code: Select all

XVal = TChart1.Series(i).XValues.Value(TChart1.Series(i).Clicked(X, Y))
YVal = TChart1.Series(i).YValues.Value(TChart1.Series(i).Clicked(X, Y))

Alternatively you could do something as in the interpolating example I implemented here.

2)I need the X axis value of the chart in datetime format as is being dispalyed on the axis label.

In that case you should do something like this:

Code: Select all

    XDate = CDate(TChart1.Axis.Bottom.CalcPosPoint(X))
    YDate = CDate(TChart1.Axis.Left.CalcPosPoint(Y))

Hi Ashutosh,

As this thread was already off the original topic I have splitted it into a new one for being easier to follow and keep thread consistency:

Hi Narcis,
The image file I already have as a file. I wish to use this image as the image point on the image point series as i have posted earlier.

Please help me with the code compatible with web application and activex control v8.
Thanks and regards

Hi Narcis,
I have uploaded an image on the given location. Please have a look on it and suggest how the same can be achieved.

Please note that there are two different kinds of images visible on the chart with Teechart Activex control.

Thanks and regards
Ashutosh

Hi Ashutosh,

Thanks for the image. In that case you only need to use default pointer styles:

Code: Select all

    TChart1.AddSeries scPoint
    TChart1.Series(0).asPoint.Pointer.Style = psDiamond
    TChart1.Series(0).FillSampleValues 10
    
    TChart1.AddSeries scPoint
    TChart1.Series(1).asPoint.Pointer.Style = psDiagCross
    TChart1.Series(1).FillSampleValues 10
