Just getting into Dash… so far I’m finding it lets me develop better data visualisation GUIs in a fraction of the time it used to take me (with matlab or IDL) despite the fact that I’m just starting up the learning curve. So, thanks!
Are there any dreams or possibilities to get this going without the overhead of passing the data through a string datatype at some point in the future? Or maybe there is a keyword/flag that I’m missing and it already does this somehow?
It’s much cleaner to have all that hidden div stuff outside of my program, but the fact that it still happens under the hood makes a big difference. In my case (started using larger data sets) I started using a store to keep a downsized copy of a downsampled/averaged portion of data I’m actually visualising. This made it possible for the code to actually execute… but a variety of callbacks all use it, and converting it to/from strings to lists (and then, inside the callbacks, a numpy array) really slows things down. A few benchmark operations take > 2 minutes using a dash store, and < 15 seconds using a global variable.
