#528 — My own values on x/y axis?

Hello,
I've got a problem with gnuplot - maybe you could help me to solve
it.
I have got a set od data - like this:
372,333,315
306,301,294
01,288,309
, and want to make similar graph like http://gnuplot.sourceforge.net/demo_4.2/heatmaps.html,
using  command
splot '-' matrix with image


My problem is that I want different axis values (e.g. the minimal x-
value will be 123 instead of zero, the maximum will be lets say 200).
I tried the xrange command, but it doesn't solve my problem. It only
tells gnuplot which area of graph to plot.

Thank you for reply.

There are several ways to approach this, but you may need to update
to version 4.4 to use them.   Here's a relevant demo from 
the 4.4 collection:

Hi ,
thank you for your suggestion, but it doesn't solve my problem. In
fact I don't have three rows and three colmns like in the example I
gave in my recent post, but the datafile is much larger. So I find it
troublesome to re-label every tick manually.
Do you think there is any other simple way to increase value of every
tick by specific value? Or to be more specific I need to perform this
job:
ticks_new_value=ticks_old_value * const + offset

Bye

Please look more carefully at the example I pointed to.
It does exactly that, using the modifiers
   origin=(60,0) dx=0.5 dy=1.5 
to re-map the coordinates of the array as it is read in.

The tick labels are not really relevant to this.
You can label the ticks however you like, automatically or
manually.

Hi,
thank you for your reply, but it doesn't work for me. I think that
problem is that I want to plot a matrix instead of picture (as is
ploted in the mentioned demo example). I tried also commands set
origin and set scale, but it is not very helpful.

try the 'using' keyword:

set xrange [1000:1300]
set yrange [0:3]
plot '-' matrix using (($1+0.5)*100 + 1000):($2+0.5):3 with image
1 2 3
4 5 6
7 8 9
