Undefined function 'graphicsversion' for input arguments of type 'matlab.ui.Figure'.

Hello,

I just downloaded Matlab_R2019a. However, after I use the plot command and try to play with the plot manually the following warning/error appears, and prevents me from manipulating the plot:

Warning: Error occurred while executing the listener callback for event EnterObject

defined for class matlab.graphics.interaction.actions.Linger:

Undefined function 'graphicsversion' for input arguments of type 'matlab.ui.Figure'.

Error in uitools.uimodemanager (line 13)

if graphicsversion(hFig,'handlegraphics')

Error in uigetmodemanager (line 34)

mmgr = uitools.uimodemanager(hFig);

Error in matlab.graphics.interaction.uiaxes.DefaultAxesInteractionStrategy/isValidMouseEvent

Error in matlab.graphics.interaction.uiaxes.Datatips/lingerEnterCallback

Error in matlab.graphics.interaction.uiaxes.Datatips>@(o,e)hObj.lingerEnterCallback(o,e)

Error in matlab.graphics.interaction.actions.Linger/enterEvent

Error in matlab.graphics.interaction.actions.Linger/motionCallback

Error in matlab.graphics.interaction.actions.Linger

In matlab.graphics.interaction.actions.Linger/enterEvent

In matlab.graphics.interaction.actions.Linger/motionCallback

In matlab.graphics.interaction.actions.Linger

Any ideas of why is this happening?

Thank you in advance,

Hi Manuel,

I have the same problem. Did you find any solution for that?

Best,

Murat

The graphicsversion function was undocumented and was removed in MATLAB R2018a.

You should remove any use of the graphicsversion function from your code. If you need to switch behavior based on the new graphics system vs. the old graphics system, you can use the verLessThan command.

if verLessThan('matlab','8.4')
    % Old graphics system
else
    % New graphics system
end

Alternatively, you can check this MATLAB Answers post for other suggestions.

Actually, I looked a little closer at the error message you are getting, and it looks like you have an old copy of uigetmodemanager.m on your MATLAB path. This indicates that you are likely using a pathdef.m from an old copy of MATLAB, or your pathdef.m is otherwise corrupted.

You should see if running the restoredefaultpath command in MATLAB resolves your issue:

restoredefaultpath
rehash toolboxcache

Note that the effects of this command will be lost when you restart MATLAB. If that command helps, you need to check your path and make sure it is not corrupted. One option to lock-in the fix is to call savepath, but that will cause any personal customizations to that path to be lost.

If this doesn't help, you should contact MathWorks technical support, and they can help you fix your path.
