Hi,
It is my understanding that you are trying to create an icon for plots on MATLAB, this can be done by using the ‘graphplot’ available on MATLAB and using the ‘waypoint’ trajectory for creating the trajectory of the plot.
For information on the ‘graphplot’ and ‘waypoint’ functions go through the documentation links below:
For creating an icon on images go through the function ‘implot’ available on the file exchange. The link for the function is given below
