The release notes for build 2012.07.121031 suggest this hasn't been fixed. Is that true?

Will it be in this new build 2012.07.121031?

Hi,

Using TeeChart Pro v2012.06.120613 32-bit VCL, exports to Excel from TChartEditor are created as .xls with its limitation of about 65,000 rows. Any plans to upgrade to allow export to .xlsx?

Thanks

Okay, thanks for your help Yeray!

Yeray, I've slightly expanded my example project with a hard-coded set-up of series values, and a memo showing the last zoomed coordinates. If I had more time today I'd hard code these zoom coordinates for you. If I concentrate on zooming in the top left part of the chart, and keep going,I get a gre...

Yeray, I modified my oroginal project accroding to your suggested workround, as attached. If you maximise the form, zoom in far enough, say somewhere between the 10th and 25th zooms, then the plot area goes grey as in the attached image, but there's no error and you can still zoom in and out at this...

Yeray, Yes, that works, thank you very much. The software now doesn't crash, but at one point during the sequence of zooms the chart plot area fills with grey and no series are visible, but we can zoom or unzoom out of that and continue working with the chart as normal. I think we can live with that...

Thanks Yeray. When's the next maintenance release? In the meantime, it doesn't seem possible to trap the error, and when it occurs the default unzoom behaviour no longer works, so users have to rebuild the chart. If you know the fix, then do you also know whether there is an obvious way of predictin...

Hi, I've attached a an example project. If you keep zooming then the error will occur sooner or later, usually somewhere between the 3rd and 15th zoom. Sometimes zooming where there's no data seems to produce the error sooner. I know it seems unlikely that a user would usefully zoom in 15 times, but...

Hi, I have a chart comprising a TAreaSeries and some TLineSeries. After a number of successful zoom-in operations without unzooming, I get 'floating point overflow'. Is this something to do with the chart being unable to calculate a tick increment? Is there a way to anticipate the error? Thanks Trev...

Thank you!

Sandra,

Thanks for the encouraging reply. I think we'd like to try modifying the source code, but I don't think your web site prices have updated to reflect the 2012 release. Is it possible, or do we have to wait for our current subscription to lapse?

Sandra, I referred to the OnClick event of the THistogramSeries, not that of the chart. If you modify your project to include the something like the simple code below, you'll see, I hope, that the event is fired only when the left axis is not inverted. procedure TForm3.Series1Click(Sender: TChartSer...

Hi, It would help my software development if TChartSeries carried extra customisable properties, e.g. an object pointer. Is that possible? For example, for me, details such as the real-world source of the data (e.g. a gauge name or location), the variate the data represents and its units, would all ...

Hi,

Using TeeChart Pro 2012.06.120613 32-bit VCL in Delphi 2007, a THistogramSeries on an inverted left axis won't fire its OnClick event. But it seems fine on non-inverted axes, and other series types seem fine on inverted axes.

Can you confirm this please?
