Default XY plot minimum?

Hi! I am modelling a particle combustion (drying, devolatilisation, char combustion). I inject one particle with a 200e-6 diameter in a 2D domain (laminar flow, finite rate chemistry).

When I try to XY plot (in the particle tracks window) the DPM Evaporation/Devolatilisation in terms of time, I get a straight horizontal line. I wrote the data into a file and I processed them using Excell. The evaporation/devolatilisation curve is now OK. Then I noticed that the problem was the maximum limit of the XY plot in Fluent. The limit was 1e-8, so the devolatilisation rate which was on the order of 1e-11 was not clearly depicted. I tried to change the maximum-minimum range in the axes panel but there was no result. The ranges changed (max=1e-11 and min=0) but in the plot window max was 1e-8 and min=-1e-8.

Does anybody knows if can I reduce this values?

/plot/solution-set> auto-scale Auto-scale x-axis? [yes] no Minimum x-axis value [0] .0000001 Maximum x-axis value [0] 100000000000000 Auto-scale y-axis? [yes] no Minimum y-axis value [0] Maximum y-axis value [0]

i think this series of command would serve the purspose

The series of command you propose, does exactly the same with the Range-Maximum change in the Axes-Particle Track panel. Imagine that when I use the the commands to change the axes range, the same time the range is automatically changed in the panel.

Thank you anyway for your help.
