Dot Plots ui design product uptime graph chart data visualization dashboard dot plot

Dot Plots are an adaptation of the Bar Graph which are specifically useful for comparing values outside of a zero baseline. By eliminating the need to show the full value range of a number, you can begin to see the very small differences in values of a small range.

For example, here I’m depicting the ‘Top Test Scores’ which range from 80 to 90. If I had used a bar chart showing the full 0–100 range, these subtle differences between the scores would be nearly invisible. However, when you scale the x-axis values as I’m showing here, the differences are much more visible. By using dots instead of bars we also eliminate the possibility of user’s assuming a zero-based axis and dramatizing the chart’s subtle differences.

They’re also useful to reduce the visual weight of a chart on a dashboard. By using dots instead of bard, the ink/data ratio goes down and our heavy bars demand less of the user’s visual attention.
