align graphs in columwise by allowing the X-scale of each plot in same length using multiplot

2
votes

I am trying to plot five graphs (a,b,c,d,e) in a column order as shown below.

The x-scale for each plot is different and they are not in a vertical line but graphs (c), (d) and (e) have almost similar x range values, that is 24.8.

When I plot these graphs in column order, I find graph labeled (a) and (b) are stretch and compressed respectively. However, graphs labeled (c), (d) and (e) are having a same scale length.

I have drawn a red line vertically to show how the x-scale of each graph is aligned. (Please see the attached figure)

enter image description here

The gnuplot script that I used is given below. 

#!/usr/bin/env gnuplot

unset multiplot

Can someone have a look into this issue and help me to get a multiplot as I shown but let the scale of each plot is align in vertical order?

It is OK if the graph size is small or big.

But I want the scale to be in line vertically.

Appreciate all your help.

Thank you.

If I edit the set xrange [-26.2:26.2] to be same for all, than I get something below.. which I dont want. I only want as how I shown in the first picture.

Just glancing over it I see that you are setting the xranges differently for each subgraph. Just sticking to one (probably the largest, [-26.2:26.2] )should solve your problem, if I understand it correctly. Without data no way to check. – vaettchen
Dear #vaettchen, I have reedited my post with making the xrange to be same to all plots. I get a graph as shown. I don't want any "down shoulder" both the side of all the plots. – Vijay

Basically you must adjust x-values of the plot size and origin such, that the widest plots keep their current size, and all others are shifted and squeezed according to their smaller ranges.

Since I don't have any data files and cannot test the whole script anyway, here is a sketch of what you need to do:

xsize(width) = 0.80 * width / width_max
ysize = 0.22
width_max = (2 * 26.2)
left_min = -26.2
xorigin(left) = 0.002 + (left - left_min) * xsize / width_max 
yorigin = 0.02
