TeeSaveToJPEGFile() raises Exception "JPEG Error # 41&q

Calling TeeSaveToJPEGFile() raises an exception "JPEG Error # 41" on one of my clients servers. What could be the reason for this?

Best regards,

Mouse wheels exist for at least 10 years now. Even if TChart V1.0 was there a few month before the mouse wheel, I don't see a reason why Steema was unable in the past 10 years to handle this in a proper way if AllowPanning is pmNone.

Support for Unicode Labels in TeeChart V8?

In the change list of TeeChart V8 you are writing:

* Canvas WideString (Unicode) drawtext support

Does this mean that you finally support Unicode labels in TeeChart V8?

Best regards,

Dear Narcis. 1. Setting TeeUseMouseWheel to False does not seem to chnage anything. 2. I would like that only those bar charts cannot be scrolled that fit on one page. But TeeUseMouseWheel seems to be a global variable and would so affect *all* charts. 3. Why did setting the AllowPanning property to...

Mouse wheel scrolls chart although AllowPanning=pmNone

I have a horizontal bar chart, and although I have set the AllowPanning property of the chart to pmNone, it is possible to scroll this chart using the mouse wheel.

Shouldn't turn pmNone the scrolling off completely?

Best regards

Thank you for the sorting code. Unfortunately it further slows down the creation of the chart. Adding values to Series that are stacked or not should be the same. But according to you workaround I additionally need to create a TBarSeries for each value. And creating all these ChartSeries seems to ta...

What is still missing is the answer to my question how to sort the Series similar to the values. Before I was using: BarSeries.XValues.Order := loDescending or BarSeries.SortByLabels; And is it possible that adding TBarSeries to a chart is much slower than adding values to a self stacked bar chart? ...

I found one more issue with your approach to create stacked bar charts: With the self stacked charts, the marks were showing the appropriate percentage. Now all elements of the stacked chart show "100%". How can this be changed?

Hi Narcis, thanks for the code. I was able to add the BarSeries at runtime, but have some problems sorting them. Before I was using BarSeries.XValues.Order := loDescending or BarSeries.SortByLabels; How can achieve similar sorting when I have stacked series instead of a self stacked chart?

Hi Narcis.

When can we expect a version in that this bug is fixed?

Can you provide sample code how to create the series at runtime?

Issues with self stacked bar chart

I just upgraded fom V6 to V7.06 and now experience several problems with a self stacked bar chart. To reproduce them, please create a self stacked horizontal bar chart with "color Each" activated and a Bar Width of 100%. Now change the "Points per Page" between 0, 1 and 2. The resulting charts look ...

you cannot display Unicode strings in native Delphi controls (at this time). This is not correct, you can display Unicode in native delphi components. Just take a look at e.g. the TNT Controls. You just need to use WideString instead of String in your methods and TextOutW() instead of TextOut() whe...

TeeChart VCL and Unicode?

When will TeeChart finally support Unicode/WideString?

Our Delphi application is Unicode enabled for 1.5 years now, the only missing part is TeeChart. It shouldn't be too difficult, because TeeChart does all the drawing by itself.

Best regards,
