Connecting user-defined points in scatter plot

[danman2tall]

Hello all,

I am trying to create a truss solving program. I would like the user to define the number of nodes in the truss and give coordinates for each node (i.e. node 1, node 2, etc). Then the user will create the truss members by defining their connecting nodes (i.e. member 1 is node 1 to node 2). I would like to create a plot of the truss to show the user what he or she is inputting. Is there a way to define the nodes as coordinates so that I could simply create another series of the nodes. I hope what I am describing is not too confusing. I have attached a small sample in which I want the four nodes to be connected according to the user-defined left and right nodes (i and j joints in spreadsheet).

You just need to plot the node pairs. I have set up 16 elements for you, can and simple extend the formula and chart data series.

That is exactly what i wanted. Thank you very much
