How to set a offset for the category axis?

[alzorin]

I have implemented a so-called dotted chart with the chart-fx library. Thank you for this great library.
Now I have a problem that the dots of the first category are not fully shown on the graph. How can I set a offset for the CategoryAxis so that the first category line is not the same as the zero line.

@alzorin unfortunately, the size of the marker (unlike the error bars/wiskers) is not taken into account when automatically computing the axis range.

However, you can set the vertical axis range manually via Axis::setAutoRanging(false) and Axis::set(min, max).

Alternatively -- if you need auto-ranging -- you could add a transparent DataSet with two points that correspond to you min/max of your initial DataSet plus the extra margins needed for the marker sizes.

There is also the Axis::autoRangePaddingProperty() although there is a preference to clamp to '0' which you may overwrite (advanced option) via DefaultNumericAxis::clampBoundToZero(..).

Hope this helps.
