Hi

I have one small problem with Mathcad plots. Mathcad plots my function only in part of it insted of filling whole XY plane. I attach my mathcad file as an example. What can I do for the plot to be bigger?2.png

From your graph (y only goes from -10 to 10) I'd guess you didn't define the range you wanted for y.  If you don't define a range, Mathcad plots from -10 to 10.

define y to be a range variable

   y:=0..180

and your line will extend to that span.

    Using a range variable as suggested by Fred may give you the better control, but the -10 to 10 limit is only there if you let chose Prime the scale automatically.

    If you click on the 180 of the horizontal axis and retype the 180 manually, you get the plot you expected

    BTW, you can do without F and "linefit" if you use simply "line"

    Wouldn't an exponential provide a better fit?
