In the recent release of new 2019b version (R2 and above), Visualizer features have been extensively enhanced:
Now users can do the following changes
Line color (blue, green,red, Magenta etc)
Line style (-, --, :,-., etc)
X axis location (top, bottom)
Y axis location (left, right)
for real and imaginary data, by default they have the same color.
if you plot real and imaginary separately, they will have the same Y axis, and you can change the line style or others:
A note about the automatic color: Only when a data set has two or more attributes, then the automatic colors apply, such as the source fields: the “fields” dataset has E and H,
However, the component of an attribute, such as “E” dataset from a DFT monitor, its Ex,Ey and Ez cannot be automatically shown in different colors.
The following script creates a matrix dataset with three attributes: R,T, and A=1-R-T:
You can edit the visualizer to show the legends:
Similarly, the scattering, absorption and extinction cross-sections can be set in one dataset and then it can show them in different color.
