Hi Chris, thanks for the hint. Because the Rotateflip method is fixed to 0/90/180/... I look for something different where I can use an arbitrary angle to rotate (the ChartImage-Tool/background image). Are there methods to attach the image to a rotated box (???) series instead of the lower left/uppe...

Hi,

is there a possibility to rotate the image of a ChartImage-Tool on runtime. E.g. I want to input the rotation angle in a textbox and rotate the image.

I use VS 2005/VB.NET.

Best Regards

Alex

Hi Steema Team!

Maybe a bug: the mark tip tool has no effect on the vector 3d. (standard marks work well) Possible you can fix this for the next maintenance rel?

Thanks in advance!

Hi Narcis, I've found the internal Chart-method to convert the e.x and e.y of the mouse-down-event: posx = TChart1.Axes.Bottom.CalcPosPoint(e.X) posy = TChart1.Axes.Left.CalcPosPoint(e.Y) The help isn't really correct, but it works (same description as CalcPosValue, difference only in the function s...

Hi Narcis, thanks for the hint. This returns the absolute values in pixel on the TChart. Using this, and the .axes.IStartPos / .IEndPos, I can scale the pixels to relative chart coordinates. By the way: is there a way to directly get the coordinates related to the Chart-axis without this additional ...

Hi All! Maybe a simple question, but I found no solution: If I click on the Chart how can I ask for the coordinates where I clicked to (based on the TChart axis)? I want to catch coordinates directly from the chart, the user should simply click on the chart... (independent of series) Thanks in advan...

Hi Chris,

thanks for your posting and the code example! The trick for internal redrawing the chart is excellent! That's what I looked for... (so I can solve the IAxis and streaming behaviour without problems...)

Thanks for your fast answers!

Best regards

Hi Marc,

thanks for the background!

I hope that may be of help.

Yes, it is. By the way, do you have a release date for TeeChart .NET v2?

Thanks!

Alex

Hi Chris, thanks for the code. Ok, lets start using this code. Two questions: - How can I add a page break between chart1 and chart2? - How can I change the aspect ratio of both charts related to their IAxisSize? (Reason: manually isometric scaling of the charts, that means I ask for the pixel size ...

Hi Chris, Yes, the one I was referring to when I said "Looking at your code" in my last post. :?: :?: :?: Please have a look into the topic "Printing AX-V7 in .NET using the PrintDocument???" in the Ax-Forum. There is the history... :?: What does this mean, exactly? You can print multiple charts to ...

Hi Chris, thanks for your mention. Narcis asked for a short example project, which I have posted. Printing multiple charts on multiple pages is only possible via streaming to an image. Please see the past postings and topics concerning this problem (Pep, Narcis). Thanks for your hint, it's not useab...

Hi Narcis, that's the problem. Is there a way to manually force a "Draw" without displaying the chart by clicking the tabpage? (e.g. TChart1.DrawSeries ???). The problem is, I cannot circle through all charts of the whole app and display... (after placing some series to the charts). I've posted an e...

Hi all! Simply create a tabcontrol and two tabpages. Place on each page a Tchart and create some data. After starting the form, ask for the .Axes.Bottom.IAxisSize of the second chart. It's zero! In a different thread I've dicussed this behaviour and asked for some information how to bypass. I don't ...

Hi all! As far as I know the EMF type is a real vector format. Why the output quality of an EMF in TeeChart is depending on the pixel resolution? E.g.: line series polygon, many points, the polygon is not longer polygon-point to polygon-point, the polygon is changed to pixel-line to pixel-line (base...

Hi Narcis,

thanks for the posting. This problem was still solved according Pep's hint (the same way like your posting).

Concerning the EMF quality I will start a new thread.

Regards

Alex
