QML Chart Y-axis padding

[johnnyparafango]

I successfully achieved an auto-scalable Y Axis, changing its maximum value each time. The problem is that when max value changes magnitude, let say from 100 to 1000, the X axis shrinks to make spaces for new bigger (or smaller) labels.

I tried to left-pad the label but it does not work with white spaces.

E.g.

 ValueAxis {
      id: axisY
      labelFormat: "%05d" // zero padding, works
}
 ValueAxis {
      id: axisY
      labelFormat: "%5d" // space padding, not works, only 1 space is printed
}

Is there anyone which achieved this?
For me is ok also to add a fixed space between the axis title and the labels, if it is possible, without using the labelFormat property.
