CircularGauge axis labels

[Tero]

For f.ex. line series I use "GetAxisLabels" event to modify labels. The same method does not seem to work for circular gauge series internal axis. Java version seems to have "AxisLabelResolver" and "AxisLabelAdapter" combo which can be used to do this (according to forum posts I found using forum search engine) but ActiveX API does not seem to have these methods.

Is there a way to modify circular gauge labels? The problem I have is that numerical values to be shown on gauge are very large (and the range is large too) so I'd like to modify them like 500 k, 50 M, 5 G and so on based on numerical value without the need to modify actual values.

Another problem. Using gauge.GetRanges().GetItems(0) etc. call seems to generate access violation fault or something similar. So I cannot add or modify ranges. I can only use GetGreenLine() and GetRedLine() function calls i.e. two ranges max.

Using latest 2016.0.0.2 release.

Hello,

This comes from TeeChart VCL so I've added it to its public tracker:

Note by default you have two Ranges (indexes 0 and 1), and you can add a third (index 2). Ie this works for me:

Code: Select all

  TChart1.AddSeries scCircularGauge
  
  With TChart1.Series(0).asCircularGauge
    .Ranges.Items(0).EndValue = 50
    .Ranges.Items(1).StartValue = 90
    .Ranges.Add 60, 80, clTeeColor
    With .Ranges.Items(2)
      .Format.Gradient.StartColor = vbYellow
      .Format.Gradient.EndColor = vbRed
    End With
  End With

Using VS2012 C++ code line:

gauge.GetRanges().GetItems(0);

causes an access violation when InvokeHelper is called:

CGaugeRange CGaugeRanges::GetItems(long Index)
{
LPDISPATCH pDispatch;
static BYTE parms[] =
VTS_I4;
InvokeHelper(0xc9, DISPATCH_PROPERTYGET, VT_DISPATCH, (void*)&pDispatch, parms,
Index);
return CGaugeRange(pDispatch);
}

Another question. Is it possible to make axis labels drawn so that they are always inside face area not over axis area:

This does not look good!

I've reproduced that problem with VC++, while it seems to work fine in VB6.
