Fairly new to using Dash. I’ve gone through the user guides and basic tutorials provided as well as finished a demo project to create a simple dashboard that plots stock price changes over time using a single drop down menu to filter stocks on/off.
I’m now trying to build a more custom dashboard for a data set of mine and looking essentially to create a heat map using a csv file that I read into a pandas data frame. However, I need to apply some python logic (aggregation/sums) to the original data frame A in order to produce data frame B which is used in the heat map and I hope that any time the filters in the dashboard are updated - it will trigger and re-create data frame B.
What is the best way to handle this or things to keep in mind? I obviously could load in just data frame B but I’d rather maintain the original data frame A as it contains more information that I need to present and then it wouldn’t be as easy to filter things off and on. Any input or advice is appreciated.
