Increase performance of dash apps

I have build a dashboard using dash in python. On initial load all graphs are empty. Graphs are then updated through call backs.

Now I am facing few performance issues with graphs :-

  1. I want to increase load time and in general performance while user is interacting with these graphs. What are possible approaches I could follow.

  2. Plotting large data sets. There are few bar & pie graphs which are getting lot of data. That means bars are very thin lines bc of lot of data on x-axis. I general how can I handle visualise graphs with lot of data.

Hi @ravi did you find a solution to this? I have a similar issue where I am facing poor performance with large datasets being plotted as a horizontal bar chart. I hoped that there was an equivalent to Scatter GL for bar charts but this doesn’t look to be the case.

hey this post is old and i think u would have foind a fix to this. Please share the solution if you have it. thanks
