[Gnuplot-info] two different x-ranges for the same plot

[<lyn...@fr...>]

Hello!


Is it possible with gnuplot to have two different xranges on for the same plot?
Eg. a function depending on a temperature  and  I  want  to  have  it  plotted
against  degrees  celcius  but  also  degrees farenheit for each shown celcius
value.
Would it also be possible to not use x2 for that but have both values (°C  and
°F) on the x1 axis?

Thanks for any help or hints

you plot the function against degree celsius. and you add a second
axis with degree fahrenheit.
for this purpose it is necessary to set the range for the first axis
and then set the according range for the second axis.

c2f(x)=x*9./5.+32.
set xrange [0:100]
set x2range [c2f(0):c2f(100)]
set xtics out nomirror
set format x "\n%g"
set x2tics axis
plot x

Thanks Johannes and Thomas for Your answers.
I'm  wondering  though,  if  it is possible in Thomas' idea to have the x2tics
only appear where there is an xtic. Can the xaxis' and  the  x2axis'  tics  be
correlated in such a way?

Thanks for Your answers and any further help or hints on this.

with fixed axis ranges and defined xtics increment, yes:

c2f(x)=x*9./5.+32.
set xrange [0:100]
set x2range [c2f(0):c2f(100)]
set xtics out nomirror
set xtics 10
set x2tics c2f(0),c2f(10)-c2f(0),c2f(100)
set format x "\n%g"
set format x2 "%g"
set x2tics axis
plot x
