Topic: suggestion for exception handling
Hi. I have using point series to plot a complex number such as 3 + 2i where I type 3 as the x value and 2 as the y values. I then decided to plot i + i^2 by typing in "i" as the x value and "i*i" as the y value (I have set "calculate with complex numbers"). The series name is displayed in the legend but nothing is drawn and no error message is produced. I think it might be useful to either allow this type of input to work, or to have an error message produce if you only want users to type in real numbers. Attached is an image of how I have done this.
