I'm using a button as a tool to plot one linear fit over a curve and I would like to replace the plot of the fit whenever I push the button again. I'm not quite sure how to use the delete command in this case. Any help is appreciated :)

You could store the handle to the fitted line in the UserData of the figure and then retrieve it every time the button is hit and use it to replace the YData of the line with the new fitted YData (this "replaces" the old line). Greetings, David

hFig = figure(); hPlot = plot(cfit); hFig.UserData.hPlot = hPlot; % Code to add the button
% in your callback hFig.UserData.hPlot.YData = newYData;
