Hi Omar,
I understand that you wanted to add x-label and y-label in Simulink Data Inspector
As of now, it is not possible to add labels for x and y axes directly in Simulink Data Inspector.
The possible work around is taking the snapshot To MATLAB figure and then add labels.
You can do that with the below mentioned workflow.
- Right click on the plot for which you want to add labels.
- Click on Snapshot-> MATLAB Figure
- A MATLAB figure window will be opened.
- To add X Label, navigate to Insert->X Label and label the x axis.
- To add Y Label, navigate to Insert->Y Label and label the y axis.
You can also refer to the following MATLAB Answer for other work arounds.
