Difficulty seeing full time plot for probe data

I've been working with some wave propagation in the structural mechanics module. I've set some of the solutions with a lot of time steps (>100,000 steps). The solution runs fine (takes a while), and I have set up a few Domain probe points on the surface of the medium the wave propagates through to see the displacement. The Study generates the plots of the probes, but it seems to only keep a portion of the data once it has chugged through a lot of time steps. I can't zoom out to see the previous timesteps, and am having trouble finding the data in the Data sets and results log. The 2D surface stress plot COMSOL makes for me however, seems to have all the data available to go back and look at.

Is there some limit on the number of points displayed in plots? Is there a limit to the number of points stored for a probe point?

Thanks for any help, hoping it's just some option for plots I am missing at the moment.

Hi

the plot length are probably limited by the Java heap size (check the KB on how to increase the Java heap)

but if you have waves, have you considered the harmonic solvers? , in some cases there are also the harmonic - transient solvers (new in 4.2a I believe, but not, by default, for all physics)

Good luck
