Physics Teacher: Trying to print graph to exact scale.

[MrOverocker]

I am trying to generate a printout of a simple Sine curve where the scale is exact so that students may be able to use rulers to accurately measure attributes like Amplitude, Frequency, Period, Phase and Offset.

My currently oversimplified table is

Time, Sine
0 ,=2*Sin(Time)
.2
.4
.6
...

This perfectly generates a scatter plot of the Sine function that ranges from +2 to -2 for how ever many cycles I want.

The problem is how do I set Excel so that when I print the chart the vertical distance between +2 and -2 on the y axis is exactly 4 cm or whatever value I select/calculate from my data.

I am using Excel 2010 and either a VBA solution or a click here, here, and here are just fine.

Thanks for taking a moment to help me teach my students.

Welcome to the forum.

That's going to be an iterative process; Excel is not intended as a CAD system. Assuming you're using a chart sheet, you would need to measure the resulting plot area, resize manually or via VBA, and set the vertical and horizontal scales appropriately. And it would vary by printer; my LaserJet scales horizontal and vertical a few percent differently.

Thanks, I was afraid of that
Oh well off to CAD then unless someone else has an idea.

Or you could plot vertical and horizontal rulers on the same graph that they could cut out.
