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. TChar...

TChart 8.02 and TeeValueSingle

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...

Hi Narcis, I have posted to the attachments group. You can see how Tchart behaves now and how I should feel it behaves. I have not upgraded to 7.07 yet. We have fixed too many bugs and added too many new features in the tchart code to upgrade very easily :-) As for the customChartRectProperty.... Wh...

isometric axes working properly

Hello, I know you have the isometric axes in the whats new demo. However, those axes are not very useful. In the demo, when you click the isometric button, adds extra blank space to the bottom axis before and after the data, so the length of axis with the data is the same on the X and the Y. However...

Thanks Narcis,

I am a source code customer, and I've already gone with the second solution. :)

OnDrawLabel is not called when drawing the depth axis

The onDrawLabel event is only invoked for horizontal and vertical axes, but not for depth axes.

Axis ZPosition property

One of the things that we're doing with the custom axes in our application is placing them at the correct location for 0 along the other axis. Previously we could achieve this with this code: LeftAxis.PositionUnits:=muPixels; LeftAxis.PositionPercent:= series1.calcXPosValue(0) - tchPlotChart.chartRe...

depth axis do not respect labelsExponent property

Not much more needs to be said about this. If you set the labelsExponent property to true for a depth axis, it still leave them as 10E4 and does not make the 4 an exponent.

Custom axes for depth axis

We currently are using custom axes so that we can move the axis to its correct position in the plot (for this we use the custom axis), while still keeping the titles outside the frame of the plot (for this we use the "real" axis, ie the property bottomAxis or LeftAxis). This works well in 2-dimensio...

I did not know that OpenGL was impossible to render in metafile format. Does that mean I have to know the final size of my graphic before I render it. That is pretty lousy. How would i render a high res image to the printer. If I do teeCreateBitmap and pass in a bitmap big enough for the printer at ...

Hi Narcis, Thank you. I will investigate that. I did not know about the environment property. If you guys ever consider a refactor, I would hope you could find a way to break the position calculation code away from the drawing code. All of the plots elements should be calculated first, before anythi...

Hi Narcis, We had a bunch of issues with this. We did not think that putting it in the afterDraw would work because then when drawing to a bitmap it would not work because the axis would be drawn initially in the wrong place, then in the right place, so there would be two lines. We eventually had to...

when to position custom axes?

Hi, We are now using custom axes for our data, so that we can place the axis in the correct position at the 0 value, while still displaying the titles outside the chart itself. We are displaying the ticks and labels on the custom axes. We are using the default bottomAxis and LeftAxis for displaying ...

Hi Narcis, Thanks for the detailed answer. Do you think I can create a fake series with no data and link it to my custom axis. As long as I set the tickmarks, min max, etc. etc the same on the custom axis as my "real axis", then do you think that should work? I should be able to have my real axis on...

Hi Narcis, How do I then tell the chart frame to leave room for the title as the chart frame is figuring out its size. Currently, it sizes the chartRect to accomodate the title. If I made the title text blank on the tChartAxis, so it does not show up in the middle of the plot, will the chart leave r...
