vylc opened a new issue #4752: [Calendar Heatmap] Improvements to make this usable
URL: https://github.com/apache/incubator-superset/issues/4752
 
 
   Calendar heatmap is a powerful visualization to show trends by week, hour, day, etc., but it is currently not very useful.
   Improvements:
   (1) Add legend to show grain of calendar. For example, if x-axis is day and y-axis is hour, show actual date values as well as hours
   
   (2) Show actual metric value in box or as a tooltip when hovering over box
   
   (3) Current heatmap is fixed and is determined by time range. Stretch to fit size of available space.
   Particularly around hourly cuts by day, trends are hard to spot when hours wrap and start a new column
   
   (4) Ability to define spectrum colors & grain
   (a)Preset colors (orange/blue, red/green, should also be color blind safe - will add in options shortly
   (b)Color picker to choose custom colors for range
   (c) Choose how many buckets to show. Current widget is defaulted at 5 (this is okay, doesn't need to change)
