Hello, I'm not sure what kink of format you're trying to show. By default Teechart gives the decimal and thousand format defined into the regional settings. As this depends on each machine, you have the ability to check the format used with the following code : TChart1.Environment.DecimalSeparator ...

I'm trying to accomplish to have numbers show with a subset of characters to use as thousand separators and decimal point. Some languages use a . for thousand and a , for the decimal point. I really need this flexibility. Does it exist?

So I take it nobody knows anything about this? Very disappointing.

Yeah, if I understand you correctly, this can be done. Use tchart's OnBeforeDraw event and then write to the DC from there. This will allow you to draw before the chart is drawn, making it look transparent. To get the DC you want, I used this function: CDC& CGraphs::GetDC() const { VARIANT & dcHandl...

Is there some way of setting the axis to display numbers that use a different thousands separator and a different fraction separator? I looked at ValueFormat, but there is very limited documentation on that, and what I have seen doesn't seem to show that it can be done. I'm using TeeChart 7.03AX Sanks

What is this function and how do I use it? Does it write the image to a variant array?

Hi Marc, I understand what you are saying, but the inter-relation of which you speak is one of non-cyclic dependency. If I want to get a portion of the Chart Internals list to be updated, it should only need to update those nodes that it depends upon first as far back as is needed prior to updating ...

Can you please add this to the wish list then?

Thanks.

Well this is better, but I would like to optimise this a bit since the InternalRepaint() function is quite slow. Is there a way of updating only one axis or only one series?

Thanks,


Adrian

What is the difference between m_Chart1.GetEnvironment().InternalRepaint() and m_Chart1.Repaint()?


Adrian

Oh, and please do not tell me to find out the information that I seek in the callback OnAfterDrawTChart() because it makes the code very convoluted.

Thanks,


Adrian

Argh! I am going crazy here! I need TChart to update its internals so that I can access the updated objects such a positions of series point, labels and such (in the container) after I move them, otherwise, my functions that manipulate the same objects but are called seperatly from different routes ...

Could you finally solve this issue using the files I sent? No, as I said before: Additionally, if I use tchart.GetTools().Add(tcRectangle) a First-chance exception is thrown (0xe06d7363). So I do not think this is going to work anyway. However, I was able to get the handle to the Device Context and...

That appears to only fire before drawing all of the axes or all of the series. I was looking for something that would fire before drawing a paticular axis or series. Do you have something like that?

Thanks,


Adrian

So I take it that there is no way to get events to fire prior to drawing a paticular axis or series?

Thanks,


Adrian
