the streamline plot does not clear in an App while contour does. How do I clear the streamline plot?

[u,v] = gradient(phi);

[strx, stry] = meshgrid(xmin:0.4:xmax,ymin:0.4:ymax); % where to draw the streamline

streamline(app.UIAxes2,x,y,u,v,strx,stry);

title(app.UIAxes2,'Streamlines')

xlabel(app.UIAxes2,'x')

ylabel(app.UIAxes2,'y')

Add the following before creating your streamline plot.

cla(app.UIAxes2)
