Bar chart is shifted on x-axis for the same x values

[kromar777]

Hello, all!
I'm plotting some spectrum data on the bar chart
renderer.setPolyLineStyle(LineStyle.NONE); renderer.setDrawBars(true); renderer.setBarWidth(2); renderer.setDynamicBarWidth(false);
I'm using one renderer and several datasets (dynamically added).
I noticed that for two or more datasets with all values equal for these datasets chart somewhat shifted along x:

However, for normal polyline style everithing is allright, the datasets are merged on top of each other as expected because one x-value coorespods to N equal y-values for different datasets:

How can I achieve this behaviour for bar-style chart? I'd like the bars exactly on their x places where they are intended to be, because it's used by a user in some decision making about specrum values as preliminary estimate.

Found it: renderer.setShiftBar(false)
