how to rotate abt x-axis?
Dec 15th, 2005, 10:09am  
I'm trying to draw a BarChart, but there is a problem that the bars r towards down,but it should be towards up.
Here i want to explain in details that in the BarChart program i draw the bars as one one rectangle,where i gave  the inputs r 'x' coordinate(variable),'y' coordinate(constant),width(constant),& height(variable).

Please help me to do as it should be...

Is the problem that the 2D coordinate system has (0, 0) in the top, left corner, with y increasing downwards?

If so, adjust the y-coordinates for the bars.
