negative values are rendered in bars about achartengine

This is not a bug, but rather a wrong usage of the APIs.
Each element in a RangeCategorySeries gets a min and a max value. Min value 
labels are rendered below the bar and the max value labels above the bar.

In the example you provided, the max value is -2000 and the min value is 0, 
which of course is not right.
Just set the min value = -2000 and the max to 0 and it will work fine.

Hello,

I'm not using RangeCategorySeries in this example, but CategorySeries. It's a 
simple BarChartView with a series with values ranging from +2575 to -2028.
I've also set the mentioned min/max Values you're referring to (+/-500 to get 
some space on top/on bottom):

if (min < 0) renderer.setYAxisMin(min - 500);
renderer.setYAxisMax(max + 500);

do I have to use RangeCategorySeries instead or is it a bug in CategorySeries?

best regards, Achim

The range bar chart was designed to be used with RangeCategorySeries.
