Charts mishandle the offset option

[inphoenitic]

I suppose the intention behind the offset setting of charts was to control the x axis start position relative to the origin of the axis.

However charts do not take 'offset = true' into account when they render the data series. Offset is only applied to the x axis!
If you set 'offset = true', the bars/points of the graph become off grid and look weird.
Also the right side of the x axis is broken.

The example displays the same chart with different offset settings. You can see that the only difference is the placement of the x axis and the grid.
