Two Boxplots for one X position using gnuplot - graph

Question

I have 2 sets of data A and B, each with a y value for x=100, 200, 300. I want to create one graph which shows the difference between these two data sets. As such this means that for each x, there will be two boxplots(one for data A and one for data B).
for example, this is how the columns are organized in my data.
DataSet A
# x=100 200 300
1 2 3
1.1 2.1 3.1
1.2 2.2 3.2
1 2 3
1.01 2.01 3.01
DataSet B
# x=100 200 300
6 7 9
6.1 7.1 9.1
6.2 7.2 9.2
6 7 9
6.01 7.01 9.01
I was able to get two graphs out of this data using:
set style fill solid 0.25 border -1
set style boxplot outliers pointtype 7
set style data boxplot
set xtics ('100' 1, '200' 2, '300' 3)
plot for [i=1:3] "A.txt" using (i):i notitle
plot for [i=1:3] "B.txt" using (i):i notitle
However, I am facing issues when combining it into one.
Please help.

Answer 1

If you want to have them stacked above each other (in case they don't overlap), then you can just combine the two plot into one with
plot for [i=1:3] "A.txt" using (i):i notitle,\
for [i=1:3] "B.txt" using (i):i notitle
If they can overlap, you may want to put them side-by-side with
set boxwidth 0.3
plot for [i=1:3] "A.txt" using (i-0.15):i notitle,\
for [i=1:3] "B.txt" using (i+0.15):i notitle
Just to give two example of how you could combine those plots.
