Main issue is Matplotlib's performance. I'm trying to plot a current
trace from a physics experiment, containing about 300,000 data points.
In LabVIEW, one can easily browse through a data set like this, but I
haven't been able yet to get such a good performance with
I agree that exploration of large data sets is an important application,
and that we need to speed it up. A couple days ago I added automatic
subsetting (but not decimation--although this could be added easily) to
image drawing, and that made a big difference for panning and zooming
using
JH Note that with the clipped line approach I suggested, you can have the
JH best of both worlds. Downsampl when N2 or some appropriate
JH number, and plot the full data when you zoom.
Hm.. Good point. I'll try to implement that. Thanks!
Best regards,

You may find this off topic, since you seem to mean by plot
a current trace something different than I'm familiar with.
Suppose I have
Hi everyone,
Quite recently I started out with learning Python, IPython, SciPy and
Matplotlib, to try see if I could replace some data analysis software
that was previously written in LabVIEW. Slowly I'm getting sort-of the
hang of it, but I've run into a few problems, and I'm now looking
around

downsampling would be a good thing to do. However, in this case, it's
really about the tiny details in the trace, so I'd like to zoom in on
