    I have Mathcad ver. 8 professional,

    I am having trouble plotting data points on a graph.

    My case in point.

    I was recording voltages at the base input of a transistor stage.
    I recorded 12 input voltages.
    I was checking Volt out with these inputs.

    Instead of drawing up a grid and making a graph, to check for linearity, I decided to use my Mathcad, I read all the instructions, on plotting graphs,
    which was very poorly illustrated, but finally figured out how to get a graph working, but the problem I'm having is Mathcad wants to put in it's own Y axis variables.

    My x axis consisted of the 12 tests. My y axis was the actual voltages measured.

    The graph plotted out these data points, however my y axis I constrained to 2.99v down to 2.32v. but Mathcad made my "y" axis from 3 to -3 so when it plotted my actual data points (voltages) it was very generalized at the top of the graph. I wanted the "y" axis to start at 2v and end up at 3v. so as to check for linearity of the data points.

    Is there a way to customize the axis on these graphs.

    I hope I explained it good enough.

    Thanks for any help..
