Hi Folks,
i have the following code.
int = A{:,4};
wl = A{:,1};
plot(wl-0.01,0,'b',wl,int,'b',wl+0.01,0,'b')
it reads in numbers from an imported excel sheet and plots it.
the numbers are read as double with 3 decimal places. i am adding 0 either side of the values to be adjusted at a later date.
the plotted line starts from the bottom of the y axis=0 and plots going up i.e. it plots going up. i want it to start at the x=0 point and plot the line going away in the x+ direction instead of the y+ direction. Any ideas how to do this?
Thanks,
Dave

%if
plot([wl-0.01,0],intt,'b',wl,intt,'b',[wl+0.01,0],intt,'b')
Use [] for adding elements and int is standard function in matlab. So i changed it to something like intt
