Length of a plotted line

Hi, I have plots like this:

I want to know, how I can get the length of the lines in the x axis in the plot. Is there a function or can anyone write a code for me ?

h=plot(2:6);

xlength = h.XData(end)-h.XData(1)

xlength = 4

Thanks for your interest. For this it worked well, but in my case there is not a continous line. The line has a lot of starting and ending points. I need a code for a automatically search after these points and than summation.

If you download the files from here, it's a simple modification

h=plot([2:4,nan,5:7]);

[start,stop]=groupLims(groupTrue(~isnan(h.YData)),1);

xLength=sum(  h.XData(stop)-h.XData(start) )

xLength = 4
