There are a few things that visdom currently lacks & some fixes:
You can't download images from environments with code. You can only use the interface to manually save images. And if you plot values, you can't recover the values in the plot - you can only download the .png of the plot. Fix: If possible, write functionality that takes the log of the environment and saves the images/plot values into directories as .npy files.
you can't merge two environments. You can only plot one at a time. To resolve, use solution to bullet point #1 to get the data from two environments, and then create a new log file that takes in the two environments' data
This is probably not possible given huge rant in visdom github thing but people are hoping that you can code up the layout of the plots you are generating in a given environment. Right now you can only use the GUI to click & drag & rearrange your plots.
