Hello Luan,
I understand you would like to plot a red/green line along with the Driving scenario plot to indicate empty/full driving spaces.
Once the scenario is plotted, you can use "hold on" and then plot a line of required colour. The “hold on” command retains the current plot so that any new plots added do not delete existing plots.
Please refer to the following documentation for more information on “hold on” function: https://in.mathworks.com/help/matlab/ref/hold.html
Hope this helps !
