alignmnet values xaxes and x2 axes

Show all headers | View raw

Hi all,
I use Gnuplot 4.6 on Linux with either x11 or wxt terminal.
I have a dataset consisting in 4 columns (analyzing workouts):
time run [sec], distanced run [m], pace [min/km], heart rate [-]
...
180, 500, 06:00, 140
---
360, 1030, 05:57, 145
...
540, 1555, 5:58, 144
...

Points are taken every 3 seconds.
I'd like to use 'time run' ans x1axes and 'distance run' as x2axes in 
such a way that when I position the mouse at e.g. x1=180 sec the info 
shall show x2=500, position at x1=360, the info shall show x2=1030. I 
didn't find the trick to get that in an exact manner. With some minor 
deviation it is achievable when set x1range and x2range to the respective 
min/max values. Autoscale will bring some larger deviation.

Is there any other trick to align the two x-axes to the values of the 
datafile?

Thanks,
Klaus
