I would like to plot long time histories of data.  A typical hdf5 file would have 100 columns and 100 million rows. I would like to plot maybe 2 or 3 of these columns ( different colour lines for each column)  against  time on the x-axis. The equivalent plot type In matplotlib would be similar to  the plt.plot(x, y, linestyle='-') . I would also like to create virtual channels with the data (statistics, sum, mean, rolling mean etc etc) .   I have been down sampling the data to plot it in jupyter  but it would be nice for the user to be able to zoom into the data interactively. Because the data set cannot fit into memory, I thought maybe Vaex or Dask/Datashader/Holoviews technology could be a good solution. Would Vaex be suitable for this type of application?\r\n\r\nDoug"}}
