Best Practices

Bump Charts are useful for showing relative positions of different entities across multiple time periods. It also allows for easy comparison of position, performance, or rankings of multiple items in respect to each other, rather than focusing on values.

For best results, make sure you add padding in the Left Value Axis panel and remove it from the Date/Category Axis panel. This ensures the lines are continuous across and the numbers easy to read.

Quick Build Notes

  1. Select a bump chart as the Visualization Type (note that as of September 2024, there is not a bump chart tile, select a bar chart on this screen)
  2. Upload your data.
  3. Change the dropdown for Chart Type to Bump Chart in the General panel.
  4. Type in the title and other text fields in the General panel.
  5. Select your Data Series.
  6. Add padding to the value axis in the Left Value Axis panel.
  7. Set the Date/Category Axis and remove the padding.
