On a Scatter I have set
ymin: -15,
ymax: 45,
xscale: true,
ylabelsCount: 12,
numyticks : 12,
And output is OK.

Now I add: xaxispos: 'center',
and the Y scale values become garbage around 0.

I expect -10, -5, 0 with the axis, 5, 10 ...
I get -10, -5, -0, -5, -10, nothing with the axis, -10, -5, 0, 5, 10...

Hi there,

Setting the ymin to a negative value when the Y axis is in the center probably won't do what you want.

There are examples of offset Y axes in the /demos/ folder (called quarter-axis charts) - but they're more involved than simply setting properties (I've even tried this with the Scatter chart).

Ok I will do it this way, thank you.

Maybe a good improvement of the Scatter would be to support xaxispos: 'zero', or even xaxispos: number?
