gnuplot - How to rescale xaxis but using the same dataset

I have the following CSV data:

-140,0
-139,0
-138,0
...
-4,240
-3,609
-2,1426
-1,7352
+0,624209
+1,7269
+2,1376
+3,553
...
+138,0
+139,0
+140,0

And the following gnuplot command:

set terminal x11
set xrange [-10:10]
set auto y
set datafile separator ","
set xtics 1
plot 'histogram1min.csv'  using 1:2 title columnheader with boxes
pause mouse

This creates an histogram with x axis with values from -10 to +10 in steps of 1.

I would like to change xaxis so -10 is presented -0.0010, -9 is presented as -0.0009 etc. -i.e. instead of using -10 to +10 we scale xaxis dividing by 1000 but using the same dataset-.

So, just to further clarify, data point -0.001 will have value 7352.

When using column 1, just do the division there. You will have to get rid of the set xrange and set xtics lines or adjust those values.

plot 'histogram1min.csv'  using ($1/1000):2 title columnheader with boxes
