An important analytical technique is to look at the rate of change over time. An easy graph to investigate this is a bar chart with the period over period change in percent or value. In this snippet, you can calculate the change for various time periods leveraging the built-in aggregation functions. If the user wants to use the aggregation filter, they can pass “aggregation” in the aggregation parameter. The “direction” field is for series to allow red/green or other types of color schemes to quickly indicate positives and negatives.
Base: Bar Chart
  • With period_over_period_direction as series
    • ‘positive’ color = #b5ca92
    • ‘negative’ color = #df5c5c
