I am "revisiting" a problem I visited in 1996, using whatever version of MathCad was current at the time. It involves projecting a beam of light on a cylindrical surface where you move the beam left and right (say from -40 deg to +40 deg), and want to "paint" a horizontal line on the (cylindrical) screen. The problem comes if you need to angle the beam above or below the horizontal -- it will draw a "Smiley", curving up or down as it moves from the midline. [Note this is an oversimplification of the problem, but this is the general idea].
I'm revisiting this using MathCad Prime 2.0. When I plot my "Smiley" (in my case, I'm going ±20 degrees and angling the beam down, so that it moves from about -14.5° at the ends to about -15.3° in the middle). The problem is the "shape" of the plot -- Prime wants to make the plot square, which exaggerates (a lot) the 1° vertical travel over the 40° horizontal range. I can, of course, "compress" the vertical by setting the max and min Y values, and I can "stretch" the plot horizontally to make it somewhat rectangular, but I cannot figure out how to either compress or stretch the vertical dimension.
Never mind -- I just found it! If you move your cursor around the edge of the plot, you'll (most of the time) see a 4-pointed Arrow cursor, which means "Move the plot in 2 Dimensions", i.e. "Relocate the plot". But if you watch carefully, when the cursor is near the center of the top or bottom edge, it can changes to a 2-headed Arrow, which is the "Resize this dimension" feature I was unable to find (until I started writing this Discussion Topic). Needless to say, I did look in the MathCad Prime Help documentation (searching for Plot Height), and in the PTC Community (same search topic), but couldn't find anything.
Is this material available? Where do I find it (what is the appropriate Search topic)? If not, please consider providing more documentation on Plots, especially on the methods available to tailor the plot to our needs.
