adjust axis scale

[Russ]

Hi: I have a waveform with around 15,000 data points that I'm plotting on x-y chart. The waveform is a sinusoid that has about 128 data points per cycle. I would like for the bottom axis scale to be in "cycles", not data points. In MathCad this is done by dividing the bottom axis coordinate by a scaler N - it doesn't change the plot at all, it just relabels the axis scale to a different unit.

Here is example:

In this sample the bottom axis is scaled in "cycles" which are just data points divided by N, the number of data points in a cycle. Is this possible with TChart?

Hi Russ,

I'm not 100% sure to understand what are you looking about. However you could try using the OnGetAxisLabel event to customize bottom axis labels or use custom labels as shown in the All Features\Welcome!\Axes\Labels\Custom labels example in the features demo. You'll find the demo at TeeChart's program group.

Narcis: Thank you again, this works great. Here is the code I used:

Count = 0
For i = 0 To 15000 Step 100
TChart1.Axis.Bottom.Labels.Add i, Count
Count = Count + 1
Next i

This puts the labels just like I want them!
