Converting Axis to Log Scale

Faizullah Khan · Post by **Faizullah Khan** » Fri Jul 28, 2006 6:53 am

Hi

When we convert the Y-Axis or X-Axis to log scale then Axis values (label values on axis) overlaped.

Thanks & Regards

Hi Faizullah,

I'm not able to reproduce this issue here using TeeChart Pro v7.0.0.8 ActiveX. Could you please send us some code or an example we can run "as-is" to reproduce the problem here and let us know which TeeChart version you are using?

Hi

When we assign minimum and maximum value to axis. like using this code

Code: Select all


For i = 0 To 500
        TChart1.Series(0).AddXY i + 2, i + 5, "", clTeeColor
   Next 

 TChart1.Axis.Left.AutomaticMaximum = True
  TChart1.Axis.Left.AutomaticMinimum = True
  TChart1.Axis.Left.Minimum = 0
  TChart1.Axis.Left.Maximum = 500
  TChart1.Axis.Left.Increment = 5
  TChart1.Axis.Left.Labels.ValueFormat = "0.00e+00"

And change the Y-axix to log scale then values of axis are over laped.

Thanks & Regard

Hi,

yes, you're correct , it's a known issue. For the moment a workaround is to use custom labels when logarithmic is set to true, displaying only the desired labels.
We'll try to improve this for the next releases.

Hi
I am unable to understand assignment of custom labe.l
so kindly provide an example of custom labels for axis.

For this line of code how we assign custom labels for the Y-Axis

Code: Select all

For i = 0 To 500 
        TChart1.Series(0).AddXY i + 2, i + 5, "", clTeeColor 
   Next 

 TChart1.Axis.Left.AutomaticMaximum = False
  TChart1.Axis.Left.AutomaticMinimum = false
  TChart1.Axis.Left.Minimum = 0 
  TChart1.Axis.Left.Maximum = 500 
  TChart1.Axis.Left.Increment = 5 
  TChart1.Axis.Left.Labels.ValueFormat = "0.00e+00"

Thanks & Regards

Hi Faizullah,

To use custom labels feature you should do as in the All Features\Welcome!\Axes\Lables\Custom Labels example in the features demo. You'll find the demo at TeeChart's program group.
