Android achartengine : bar chart - bars appear upside down

Question

Am trying out to plot some values using achartengine in an Android App. The values in y axis are usually negative. This is how the bar chart appears

But I want it to appear from the bottom i.e. I want each bar to start from -100, instead of the current 0. How do I do this? Please help.

I suggest you build a range bar chart instead of the current bar chart. Another suggestion is to use renderer.setBarWidth(widthInPixels) in order to set the width of the bars. This method works best when you have only one item per series.
