I have to put an arrow at a specific position on the figure. I am trying to change the position of the arrow using the property inspector. But an error is thrown out " ERROR SETTING PROPERTY "POSITION" OF CLASS LINE "NaN is not supported". This is the first time i came across the error. I am using MATLAB2020. Kindly help me to solve this.

I'd never used the function before -- but w/ R2020b I get same symptoms -- couldn't change anything in the position vectors.
Looks like a bug to me; submit service request to support@mathworks.com

Hi Naveen K S,
I understand that you are facing an error while trying to change the position of the arrow through property inspector and encountering an error.
This is a known issue and our team is working on it which may be resolved in the upcoming releases, in the mean time here is one of the possible work arounds which you can try:
You can get the object programmatically and access it using dot operator as follows:
1) Click on the object to select it with the Edit Plot tool (the white cursor icon)
2) Without clicking anywhere else in the figure, switch to the MATLAB Command Window
3) Enter the following commands to change a property
gcf
objectHandle = f.CurrentObject; % returns a handle to the selected object (here it will the arrow)
objectHandle.<property name> = [0.58 0.58]; % change any property programmatically
4) Switch back to the figure window
I hope the above-mentioned information resolves your issue!!
