Hello Satyajit,
As per my understanding, you are experiencing an issue with the "More Properties" window in MATLAB R2018b on Ubuntu 18.06 LTS.
Please note that the black popup window you are seeing is likely a rendering issue. There are a few possible solutions you can try:
- Update MATLAB: Make sure you have the latest version of MATLAB installed. Updates often include bug fixes and improvements that may resolve the issue you are facing.
- Restart MATLAB: Sometimes, restarting the application can help resolve temporary glitches or rendering issues.
- Use alternative methods: If the "More Properties" window continues to show a blank popup, you can try accessing the desired options through alternative methods. For example, instead of using the "More Properties" window, you can directly modify the properties of the ellipse object using MATLAB commands. The rotate function, in particular, can be used to rotate the ellipse.
Here is an example of how you can rotate an ellipse using MATLAB commands:
% Create an ellipse
ellipse = imellipse(gca, [x y width height]);
% Rotate the ellipse by an angle (in degrees)
angle = 45; % Specify the desired rotation angle
rotate(ellipse, angle);
By using MATLAB commands, you can bypass the need for the "More Properties" window and achieve the desired rotation of the ellipse.
For more information related to rotate function you can refer to the following article:
I hope it helps.
