Hi I am working with Cursors. Please tell me the difference between below two statements. In what conditions each one to be used. Always confued to choose from them. And there are many cases where both are not same. cursorTool.GetVertAxis.MinYValue and cursorTool.GetVertAxis.Minimum Regards, Rajesh ...

Hi Yeray.

We are creating WPF application not the Win-Form Application.

It will be great if you check for WPF appplication as well.

HI Yeray, Thanks for your reply, Here is the bug in TChart. Clicked Method always return -1 irrespective of the mouse position. Even mouse pointer is over the contour line it returns -1. I tried with zoomed data also, result is same. Please confirm that and let me know where to change in Tchart code...

Hi, I have contour displayed. Requirement is that When ever user performs mouse hoover over contour line, Mouse should change to some business icon. Problem is that T chart is not giving any event like mouse enter or mouse leave on the Contour segments/levels. Please tell me how to achieve that . Ra...

Hi Yerey,

Business req doesnot allow me to deactivate any of the cursor..

What to do now?

I have created two cursors in following Order in my WPF application. (Please find Attachment) 1. Orange (With Larger height) 2. Green (With Shorter Height) When Super imposing both on same value. Green Cursor appears on top. But when I tried to grab the green cursor from green area, Orange cursor is...

Exactly you got right now.

Is there any possibilty that you can provide downsampling algorithms to me so that i can implement by my way in my application.

or you can provide any references to it.

Thanks,

Rajesh

No No.. not that way..

I mean from decimation is Downsampling of contour data.

like in Fastline series downsamples data if we provide Downsampling object to functions property to reduce the number of points in series.

But Contour doesnot provides downsampling.

Hi Narcís, Thanks it worked, but it did not solved my original intention of increasing the performance of loading 1024x1024 points on the contour. The only solution i think now is to reduce the number of points from my original dataset and give that decimated points to chart. But sadly :( Tchart doe...

hi,

But in the above code compiler doesnot allow me to do the following statement

contour.YValues.Values =yData

error is I cannot asssign multi dimension array ([][]yData) to contour.YValues which is single dimension array

I am stuck up

Hi Is that correct way to populate a contour; double[1024] xData = {1,2,3.....1024} double[1024] zData = {1,2,3.....1024} double[1024] [1024] yData = { {1,2,3.....1024}, {1,2,3.....1024}, {1,2,3.....1024}, ....... } Contour contour = new Contour(); contour.XValues.Count= xData.Length; contour.XValue...

Hi, Thanks for reply, On reviewing T chart's code i found that using DataSource Property has no performance gain to call of Add() methods while displaying 1024x1024 points on contour. Because TChart internally performs the Contour.Clear() and making calls to Add() methods, with overheads of creating...

Hi, By looking properties of Contour class it seems that we can Display contours using DataSource Property. Please let me know that how to prepare a DataTable or any other DataSource to Display the Contours . The points on countour will go upto 1024x1024 I need to frequently update the Contours with...

Hi,

I am facing a bug in the UndoneZoom event of the Tee chart.

In the event handler of UndoneZoom when I am trying to access the Minimum and Maximum of the Bottom Axis, it gives me the Minimum and maximum of the Zoomed state. Is that a bug in the TeeChart?
