Automating MathCAD Graphs 1

[Mistry88]

Hi All,

I am pretty new to MathCAD so forgive me if this question is simple.

I am trying to create pump curves for several pumps in parallel. I know the original pump data and have successfully managed to plot a 2-D graph of the pump curve when 9 of the pumps are used in parallel. On the same graph I have a curve for 1 pump, 2 pumps, 3 pumps and so on.

My question is, is it possible in MathCAD to have a variable that defines the number of pumps in parallel and therefore the number curves on the graph?

I am trying to avoid having to manually enter the individual functions on the graph.

It would be great if someone could point in the right direction to find out how to do this. I have tried the help files and google but not found anything that explains how to do this.

Which version of Mathcad have you got?

If you don't mind losing the differing colours and y-axis labelling, then you could create a matrix with each pump curve in a separate column, then plot the matrix in a 2D (x-y) plot.

You could multiply the y values of each pump by a (pump_number<=number_pumps_to_plot) factor. this will suppress the display of alltthe extra ones.

Another option is to use Excel instead.
