Options¶
The Run Chart dialog ("Run Chart Analysis") has a single Data tab; there are no separate analysis settings. Everything you control is which columns play which role.
Data Tab¶
- Excel / GroupBy: analyze flat Excel columns (default), or split the data by one or more GroupBy columns so each group gets its own chart
- Data Types: a per-column dropdown to reclassify any column if it was detected wrong
- X Column (Optional): at most one column supplying the horizontal axis values (Continuous, Integer, Count, or DateTime). With no X column, observations are numbered 1, 2, 3, ... and the axis is labeled "Observation". DateTime X values are shown as dates.
- Y Columns: the series to plot (numeric columns only; DateTime cannot be a Y). All eligible columns start selected; each Y column becomes a series.
- Overlay Datasets on a Single Chart: on by default; combines the Y series into one chart with a legend. Available when two or more Y columns are selected or a GroupBy column is used; otherwise each Y gets its own chart.
- GroupBy (visible in GroupBy mode): pick and order the grouping columns, with time buckets for DateTime columns
A column can hold only one role: choosing it as X grays it out in the Y and GroupBy lists (with a tooltip explaining why), and so on.
What the chart shows¶
The run chart is a direct plot of your data in time order: a line with markers per series. Points with missing values are skipped, and a series needs at least two points to be drawn.
No statistical tests
Quantum XL's Run Chart draws the data as-is. It does not add a median or center line and does not run pattern tests. For control limits and out-of-control tests, use the Control Charts.
There is no task pane for Run Chart; to change anything after creation, run the tool again. A maximum of 100 charts is produced per run.
