I have a LogarithmicAxis that has a minimum of 125 and maximum of 16000 but I need it to start at 0 and then go to 125,250... But as it is Logarithmic, if I put minimum to 0 I will have 0, 2,4...

How can I achieve this?

Hi Bárbara,

In order to have labels 125, 250, 500, ..., you need to set a Minimum of 125 and a LogarithmicBase of 2. Having a zero on the logarithmic axis, however, is a no go. This is simply because a zero is an undefined value for the logarithmic axis.

The labels of the axis, simply put, are 125 * (base^pow). In your case
125 = 125 * 1     // 1 == 2^0
250 = 125 * 2     // 2 == 2^1
500 = 125 * 4     // 4 == 2^2
1000 = 125 * 8     // 8 == 2^3

And because you cannot get a 0 from 2^x, the 0 is undefined for the logarithmic axis. Let us know if you need more information.
