TChart 8.02 and TeeValueSingle

David Novo · Post by **David Novo** » Fri Feb 15, 2008 7:34 pm

Hello All,

It seems that the TChart source will not compile if the TeeValueSingle directive is set. The first failure we found was at

TChartSeries.XValue
TChartSeries.YValue

The properties is defined as TChartValue but the setters take in a double

Another thing is that TIsoSurfaceSeries.YPosition is set as a tChartValue instead of a double. Why would the YPosition be a TChartValue?

Are we the ONLY people using TChart with TeeValueSingle? How many people really need double precision charting values?

Thanks for reporting. I've added the defect to our bug list (TV52012826) to be fixed for next releases.

I've also added this to our wish-list to be reviewed and considered for enhancement in next versions.

Hi Narcis,

Thank you for looking into this. However, I think you misunderstood my last point.

Currently, TChart is not compiling with TeeValueSingle and one of the reasons is because TIsoSurface.YPosition is partially set as a TChartValue. I don't care one way or another which one it is, (i.e. TChartValue or double) but it does not seem appropriate for it to be TChartValue.
