Have a look--here’s your kink, at π/4. I have no idea what you are plotting here. Your "fake" does not look like a _function_ of either axis, and it also doesn't have the symmetry of the sin/cos pairing of my code. So if it is neither a function in isolation nor the actual value pair, what is it? Care to show the program you are generating your plots with? -- David Kastrup -- cairo mailing list [email protected] https://lists.cairographics.org/mailman/listinfo/cairo
