Merging two plots in matlab

votes

I am looking for a way to merge two Matlab plots. I have the figure files for each of them as fig1.fig and fig2.fig One figure contains a plot which runs for a certain range e.g 1 to 100 and the other figure contains the continuation of the first plot e.g 101 to 200. Each of these plots takes around 8 hours, so I do not want to replot them. Is there any simple way of merging these two plots?

It sounds like you want to join up your data, so you need to extract the x and y data from each of your plots. If you have a line plot, you can load the first .fig file

e.g.

enter image description here

and then type

a = gca
handles = findobj(a)
isLine = strcmp(get(handles, 'Type'), 'line')
XData1 = get(handles(isLine), 'XData')
YData1 = get(handles(isLine), 'YData')

That will extract the x and y data for your line, from your first plot.

Now close all your figures and load your second plot:

enter image description here

a = gca
handles = findobj(a)
isLine = strcmp(get(handles, 'Type'), 'line')
XData2 = get(handles(isLine), 'XData')
YData2 = get(handles(isLine), 'YData')

You can now plot your merged plot with:

figure
plot([XData1 XData2], [YData1 YData2])
title('mergedPlot')
