This "Copy to clipboard" feature is not present anymore in the upcoming Octave 5 release.

It may be reintroduced in the future, when Octave has a command line way to do that (e.g. the "-clipboard" print option).

Closinr report since it won't be reproducible.

I'm noticing a plotting issue when calling up script to generate plot values. It's acting like the x,y,z coordinates don't exist. I was using a basic temp example from a matlab script to confirm the issue.

Would calling out Plot fix the issue..? The script I wrote worked fine but seems all the scripts can't generate the image so it seems like logic issue in the script.

Maybe try making the decision process more simplify like matlab.

Do you see the same delay when saving a figure, for example with "print myplot.png"? If so, then this may be a duplicate of bug #46910, long delay when printing a figure to a file in a format that requires ghostscript.

using qt plot
when copying a graph from surf plot, and then pasting it when the data values are high or low, there seems to be a long delay, maybe due to the number of points but whether it is due to impatience on my part or the system taking a very long time.
This might be the system calculating and trying to get the data for the image, e.g. x,y,z is probably 10,000 + points in total.

When I print screen or paste the data is not pasted and the system takes a long time to respond so I have to close Octave and restart again.

Make a surf plot with 100x10x100 points, go to edit, then go to copy and try to paste it quickly in an email application.
I have many tabs open at present in google chrome and a lot of memory is being used too so this would also be an interesting thing to try out in repeating the problem.

Is this the same as the one below?
