I copy some document for you here, wish it can help you.
1-->Setting axis scales by code
You can change the Maximum and Minimum at runtime using this code:
With TChart1.Axis.Bottom
.Automatic = False
.Maximum = 36
.Minimum = 5
End With
You may set Axis scale Maximum and Minimum to automatic individually. eg:
With TChart1.Axis.Bottom
.AutomaticMaximum = True
.Maximum = 36
.Minimum = 5
End With
2->Increment
You may tailor the intervals for the Axis. Select the Desired Increment combobox from the Scales section of the Axis page and add the increment you require. You may change this by code at runtime:
With TChart1.Axis.Bottom
.Increment = 20
End With
