Custom fonts in graphs and Graph Drill Down

Hi,

  1. I would like to use custom fonts for the graph, but i couldn’t see any methods to do this from the panel. Is it possible to do it by editing the redash source code (for self hosted account). What do you think?
  2. I would like to create drill down graphs, ie, when we click on a bar or line in graph, it should show another graph with more details about that particular item that we clicked. I couldn’t see any methods to do this from the panel. Is it possible to do it by modifying the source code?
  3. I would like to export widgets in a dashboards as a pdf, is it possible?
