For the current plot type (where data points are connected by lines), certainly. It would probably be possible to plot denser data sets by a point cloud type plot, but that would make denser data series harder to read. > I guess even if not, eventually at a low enough interval the round > trip and plotting intervals would need to be decoupled, no matter what > plot type is used.

Hmm, seeing as we probably want to keep all the data points in the Flent data file anyway, I think we might as well do the sub-sampling in Flent. Just thinning the plots is a few lines of numpy code; just need to figure out a good place to apply it. Handling loss is another matter, but one that I need to deal with anyway. Right now I'm just throwing away lost data points entirely, which loses the lost_{up,down} information. Will fix that and also figure out the right way to indicate losses. -Toke -- You are receiving this because you commented.
