Unable to get data from multiple topics easily #598

Open rickyleal2 opened 3 years ago

rickyleal2 commented 3 years ago

I am trying to display data from multiple topics in plot panels and then download all the data in CSV files. I have over 30 topics

I tried using a Tab Panel containing multiple Plot panel per topic but switching tabs erase previous data on the panels. I also tried using independent Plot panels but having too many plot panels does not allow me to visualize the data properly. I also tried having a single plot panel with all the topics but this is not ideal. Moreover, there is a point where I can't add more topics to the plot as the list of topics gets too long to fit on the screen.

Is there any way I can keep the data on the plots after switching tabs?

You could try using Node Playground to take multiple topics and merge into one before publishing: https://github.com/cruise-automation/webviz/blob/master/packages/webviz-core/src/panels/NodePlayground/index.help.md#using-multiple-input-topics

We tried using Node Playground but that approach did not solve my problem. What would solve my problem is data persistence when swapping between tabs
