Question

I am plotting a bar graph using core plot for both positive and negative values.I want a line at x=0 seperating the positive and negative values .Can anyone tell me how to set the axis line

thanks

Answer 1

You need to set the orthogonalCoordinateDecimal property of the axes. So for example:

        yAxis.orthogonalCoordinateDecimal = CPTDecimalFromDouble(0); 

will make 0 the point of the yAxis where the yAxis crosses the xAxis.
