Plotting Complex Data in Mathcad

Watch out for complex numbers in your data, which can not be plotted in Mathcad. Imaginary parts in your numbers leads to either incomplete graphs or errors instead of plots. To work with complex numbers, you can plot the real and imaginary parts of your numbers separately, or reframe your data to calculate only the real part before plotting. Mathcad 2D plots skip numbers that have an imaginary part.

You can separate the real and imaginary parts before plotting using Mathcad's **Re** (returns the real part of a complex number) and **Im** (returns the imaginary part of a complex number) functions.

See the attached file for how to do this for both 2D plots and 3D plots.
