I'm currently working with cylindrical coordinates (r, theta, z), and I decided to test some simple graphs before I began working. The first graph I tested was r = 3 which should have yielded a cylinder, but I got a sphere instead as if I had graphed the equation in spherical coordinates! I decided to create a point set to see whether the app could plot cylindrical coordinates correctly by creating points with r = 3, and the points seemed to form a cylinder. So apparently, grapher can plot correctly in cylindrical coordinates, but not graph! Ideas?
