I use the following code in one application: with TPNGExportFormat.Create do try Panel := AChart; PixelFormat := pf24Bit; SaveToFile(Filename); finally Free; end; I tried to use this code in another application, but I got the following message: Access Violation at address 0012F6A0. Write of address ...

Thanks Narcis, it works great!

What about obtaining the value from CalcZPos? This requires a series ValueIndex. You could find it using Series1.ZValues.Locate which already uses a double value and returns a ValueIndex.

Hope this helps!

Excellent, but it seems that there is no CalcZPosValue. How can I replicate this function. Hi Normand, What about using MoveTo3D and LineTo3D methods with X,Y and Z coordinates? Something like this: Chart1.Canvas.Pen.Width:=3; Chart1.Canvas.MoveTo3D(X0,Y0,Z0); Chart1.Canvas.LineTo3D(X1,Y1,Z1);

I am drawing lines between selected points of a 2D using standard Canvas operations (MoveTo, LineTo), CalcXPosValue and CalcYPosValue. I am doing this using the BeforeDrawSeries event. The result is exactly what I expect and look like this: http://www.simstat.com/Network.png Now I would like to do s...

Can we expect a new version in 2007?

If not, can you suggest a way to implement this with the current version?

Is there an option to set the text on a connecting line to have an opaque (white) background so that one can read this text easily even when it is over the connecting line?

If not, please consider this a suggestion.

I need to store some information along with a chart in order for another application to read it and interpret it (the information I would like to store is the application used to create the chart and the chart type). Ideally, I would like this information to be stored in the .tee file (and transferr...

Is there a way to store a TChart (data, settings, etc) into a Blob field?

No luck! The problem still occurs in v7.07. Any suggestion on what I should try to do next?

Then can you please try if v7.07 works fine at your end?

Thanks in advance.

Which TeeChart version are you using?

Version 7.06. I always get an Access Violation error when calling this procedure.

I would like to export a chart into a PNG file name. I declared all the required unit and I already have a file name.

This procedure does not work. Obviously something is missing:

with TPNGExportFormat.Create do SaveTofile(Chart1,filename);

What is missing?

the only way to know how many labels has been displayed in the Axis would be by checking each axis label size and compare the sum of all with the axis size.. Actually, it should be the size of the longest one multiplied by the total number of labels, since while most labels may be short, and may be...

Sorry but I have no idea what you are talking about. Suppose I have 20 labels associated with 20 values and I need to draw a barchart. If the barchart is too narrow, it may draw only 8 or 9 labels. None of them are numerical values. Even if I implement your method, I will always get back a value of ...

Quite easy, create a new application, a TChart component, add a Pie series, go to the editor, put a check mark beside Circled and remove the one in the 3 Dimentions checkbox. If you leave both items checked, you will get a round pie in 3D, but if you display the pie in 2D, it will not be round but o...

The series1.circled option used to obtain a round pie chart does not seems to work when one screen is used portrait mode. It seems like the algorithm create a ratio without taking into account the fact that the height may be bigger than the width. Any way to fix this so that this option works for bo...
