I often want to switch this around so that the independent variable runs on the vertical axis and the dependent on the horizontal. I feel sure there ought to be a simple way to tell Plot to make this change but I have never found it and instead have resorted to convoluted approaches. Can anyone tell me what the simple trick is, if it exists? > Thanks > John Finnigan Hi, I just found this looking for the answer myself. Then it hit me: try changing the order that you define the variables within the plot operation. So as an example, given: ContourPlot[ Evaluate[Re[ Product[x + I y - (a + I b), {a, -2, 2}, {b, -2, 2}]]], {x, -3, 3}, {y, -3, 3}] To swap axes, just define y and then x -- like this: ContourPlot[ Evaluate[Re[ Product[x + I y - (a + I b), {a, -2, 2}, {b, -2, 2}]]], {y, -3, 3}, {x, -3, 3}]
