Hi,
I am assuming that when you say inner axis labels, you mean the labels representing the constant frequency and constant damping grid lines. As of now, there is no direct way to do this but you can try this work-around:
- Run the following code.
P = pzoptions;
P.TickLabel.FontSize = 0.0001;
P.Grid = 'on';
pzplot(tf([1],[1 5 10.25]),P);
- As a result of setting the TickLabel.FontSize option to a very small value (0.0001). The tick labels along the X and Y axes will also shrink and seem invisible.
- To rectify this problem: Open the figure => Navigate to ‘Edit’ => Click on ‘Axes Properties’ => Go to ‘FONT’ and change FontSize to a bigger value (say, 14).
- Close the Property Inspector, changes should be reflected in your plot.
Please note, I am using MATLAB r2022b. I've attached my final plot.
