The problem is the function f.C1 because you used square brackets. Using square brackets creates a matrix which is not what you want.

So use normal parentheses and the sheet works.

But your range variable epsilon.C consists of only four numbers (0, 0.001, 0.002 and 0.003) and so your plot is just connecting four points.

Hi

Change the square brackets, and plot using a mid range of 0.0001 not 0.001

Do you mind if I ask another plotting problem? I want to plot a Moment - rho graph and I don't know how to plot it. How do I plot it with only using equation for both limits that have a dependent variable rho in its nominal moment.

Thank you.

Hi,

Please include the worksheet which allows us to work with the sheet to answer your questions.

The two moment equations are equivalent.

What if my I have a limit that is rho min which is equal to 1.4/Fy and rho max which is equal to rho bal that is why in my previous program it has limits on its rho. Thank you.

Hi.

Don't put your math regions embedded behind a text block as it makes it very hard to edit, Use units on the variables in math region not on foreground text block

Change your range variable

A range variable construct is simple: "start here", "second point", , , :"stop here"

so the second point (minus the first) sets the step delta. You currently have a three number range variable, Changing to the above gives a finer division of points to draw straight lines thru,
