Run Chart¶
Plot data points in sequence to visualize trends, shifts, and patterns over time.
What is a Run Chart?¶
A run chart is a simple line plot that displays data points in sequential order, connected by lines. It shows how a measurement changes over time or across observations. The X-axis can be a time column, an index column, or auto-generated observation numbers if no X column is selected.
When you have multiple data columns, they can be overlaid on the same chart for easy comparison, with each series shown in a different color.
When to Use a Run Chart¶
- When you want to track a measurement over time
- When you need to spot trends, shifts, or unusual patterns visually
- When you want a quick visual check before formal SPC (Statistical Process Control) analysis
- When you want to compare multiple series on the same chart
Example Output¶
A typical run chart shows data points connected by lines along a time or observation axis. Multiple series appear in different colors with a legend identifying each one.
