When I use the barChart , my code crashed with exc_bad_access

[vesper305]

It seems that the code: [barChart strokeChart] , was trying to release some memory that has already been releaseed.

I can't figure it, so I post it.

Have a nice day :-).

Same here. I traced the exc_bad_access error to the following line in PNBarChart.m:

NSString *labelText = _yLabelFormatter((float)_yValueMax * ( (_yLabelSum - index) / (float)_yLabelSum ));

A quick fix is replace that with:

NSString *labelText = @"";

The Demo app uses the following code that seems to work:

self.barChart.yLabelFormatter = ^(CGFloat yValue){
            CGFloat yValueParsed = yValue;
            NSString * labelText = [NSString stringWithFormat:@"%1.f",yValueParsed];
            return labelText;
        };
