Status: Answered => Solved
Eugen Kubowsky confirmed that the question is solved:
@bruno: done ;) berlin is listed as user location. Are you sure about the wiki?
what have you done to fix stability issues?
@Anton: Yes, I know how to observe the batch status using webbrowser of the
simulating computer localhost:9080 by defaut. But thanks for asking ;) this is
an amazing feature of Yade btw.
I solved my problem. The problem was at an other part of the code.
So it is indeed possible to use plot.addData() multiple times for your plots.
Heres an example of the saveGnuplot-Output of my data.
t, t_perf, and t_xyz represent simulated time (so called virtPeriod).
t and t_xyz are the same. I just added t_xyz because I want Fx,Fy and Fz be
plotted in a diffrent window than Fmess and Fn.
You're right Bruno, the columns of the global yade plot table have to
have the same length. But calling plot.addData() will take care of it by
inserting 'nan' to all columns which are not specified inside the
brackets of addData().
# Fmess Fn Fx Fy Fz
speed t t_perf t_xyz
nan nan nan nan nan 46.1 nan 1.0 nan
nan nan nan nan nan 43.5 nan 2.0 nan
nan nan nan nan nan 39.5 nan 3.0 nan
nan nan nan nan nan 39.4 nan 4.0 nan
nan nan nan nan nan 39.9 nan 5.0 nan

so it is possible to create to Engines that plot different data at different
times.
Here's an example, maybe we can add it at the plot.addData documentation?
O.engines+=[ PyRunner(iterPeriod=1,command="myAddPlotData()",
label='plotPlotter', dead=False),
PyRunner(iterPeriod=2000,command="updatePerformancePlot()",
label='performancePlotter', dead=False)]
#...data producing part
# In some cases it is useful to set the "dead" flag of one or both of the
"plotengines" to True. Doing this you can start plotting at a certian time or
iteration by changing the flag by e.g. plotPlotter.dead=True
plot.plots={'t':('Fn', 'Fmess',), 't_xyz':('Fx', 'Fy', 'Fz',),
't_perf':('speed',)} #creates 3 different plots
fig=plot.plot(noShow=True)#because I use batch mode I dont need the plots to be
plotted, besides it will raise a warning
O.run(10000) #run 10000 iterations
O.wait()
plot.saveGnuplot(baseName='savedPlot')
def myAddPlotData():
force=plot.addData(t=O.time, t_xyz=O.time,Fn=normalforce, Fmess=Fm,
Fx=Fx,Fy=Fy,Fz=Fz)
def updatePerformancePlot():
plot.addData(t_perf=O.time, speed=speeddata)
