[rrd-developers] Re: Area above area and RPN Exp.

[Anuj Jain]

HI
i am able to solve my problem like this but in the process i lost my original DS name. Can anyone of you help me.
Briefly what i am doing: I am trying to make graph using area. So i have to plot the lasrgest area first the next and the last will be the lowest value.
So i find max first then compare with each value which it matches and then make it zero. and so on.
Since same ds name cannot be used so i have to use diff each time. in the process i lost the original ds name.
