Real Time plotting in MATLAB GUI

I have to plot scatter x-y coordinates on a GUI which will have a image loaded. The scatter plot is to be plotted on the image. I don't want the axis of the plot.

I have to receive the data from python code. The data will be coming at a rate of 60 samples persecond. I have to plot each scatter and also refresh the plot so that the previous points do not show up.

Please help me in this.

Hi,

You could point all the points in one iteration and change their locations in the next second. So suppose you plot 60 points in first second, then you could update the position of the first 60 points so that they match the next 60 points. You could do that by changing the XData and YData properties of the plotted points. For the second query, you could use the line "axis off" to make sure that axes aren't drawn on the image.

Refer to the following link for more information on plot properties

Use animatedline() with MaximumNumPoints https://www.mathworks.com/help/matlab/ref/animatedline.html#bud1f5d-1_sep_shared-MaximumNumPoints
