Android Question [xChart] Force axis to start from 0

[angel_]

Although autoscale works very well, sometimes, I would like to force the 'y' axis to start from 0, is this possible?

For logarithmic scales it is mathematically IMPOSSIBLE.
You can set the min value to 1, 0.1, 0.01, 0.001 etc but NOT to 0!

What you can do is to set manual scales, for example:

    LineChart1.YScaleLogaritmic = True
    LineChart1.AutomaticScale = False
    LineChart1.YMinValue = 0.1
    LineChart1.YMaxValue = 500

While testing I found a bug with manual logarithmic scales, the xChart thread has been updated.

Can you perhaps do something like this based on a given filter or criteria:

Dim v As Int =Rnd(.1, 10001)  'certain criteria
         If v < = 100 Then
              chart.AutomaticScale = True
         Else
               chart.YScaleMinValue =1
          End If

A scale value of '0' has no meaning in logarithmic scales !
You will nowhere see a chart with logarithmic scales begin with '0', look in the internet !
