Description:
This example shows how to create run chart to check the pattern of subgroups.
A Run Chart, also known as a run-sequence plot, is used to study collected data for trends or patterns over a specific period of time or an ongoing process. You can use it to monitor data over time to detect trends, shifts, or cycles, to analyze evidence of special-cause variation in your process.
Origin's Run Chart plots the collected data by specified subgroups; each subgroup contains the observed data from the same time. All observed data will be plotted as vertically arranged dots by subgroups, and the mean or median of each subgroup will be plotted as Line+Scatter plot against the time series. A horizontal dash line at mean or median of whole input data will be added as the reference line.
