Implement downsampling in dimension reduction plots
Goal / Use case
The goal is to speed up loading and display of the dimension reduction and gene view pages.
Tasks / Implementation
- Implement a downsampling approach: The creator of the page can set a percentage of samples to be shown. These samples will be drawn randomly, other samples will be discarded.
- Check how severe a downsampling approach distorts the statistics from linked charts. Do the gains in speed enhance the user experience drastically? Decide if it is worth to omit a certain number of samples for a speed-gain!
- Check if downsampling can be implemented for viewing only, but statistics and download are still full data sets. How is the speed-up now?
