Operating System: Win2K

Newbie here, so sorry if this is a simple question. Couldn't find a previous post to answer this.

I would like to know if I can fit an "upper bound" line to a set of data. Say, for simplicity, I have a sinusoidal line, is there an easy way to generate the upper bound of that graph? In this case, it would be a straight line. My data deals with trying to show bearing areas of machined parts.

thanks.

Hi,

If you just want to draw a line at max value of the plotted dataset, you can use script code such as below in the script window (copy and paste these lines of code, then highlight both lines and hit the Enter key):


sum(%c);              // Compute stats on active curve;
draw -l -h sum.max;   // Place a horizontal line at max value;



If you are looking to create a top/bottom envelope line for your data, see this free add-on:
