Problems with histogram


I have a series with values positives and negatives. I’d need to draw a column chart like the example here

Where the yaxis is centered on 0 and columns go up if positive and down if negative.

I tried a lot but I always get the columns with basement at the bottom of chart.

Any help?




Damn I’m so noob…  :zipper_mouth:

SChartColumnSeries *c = [SChartColumnSeriesnew];

c.baseline = [NSNumbernumberWithFloat:0.0f];
