Home / Statistical Tools / Analysis Tools / Dotplot / Options
Options¶
The Dot Plot dialog ("Dot Plot Analysis") has a single Data tab; there are no separate analysis settings. Everything you control is how the data is selected and grouped.
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 dot plot
- Data Types: a per-column dropdown to reclassify any column (Continuous, Integer, Count, DateTime, Nominal) if it was detected wrong
- Data Columns: the columns to plot. Continuous, Integer, Count, and DateTime columns are allowed; Nominal columns cannot be dot-plotted.
- Frequency Data (Optional): a Count column whose values act as repeat counts for each row. Each selected frequency column produces its own set of charts.
- Overlay Datasets on a Single Chart: combines the selected columns onto one chart with a shared scale (off by default)
- GroupBy (visible in GroupBy mode): pick and order the grouping columns; a DateTime grouping column additionally offers a time bucket (Year, Month, Week, Day, and finer)
Automatic behavior worth knowing¶
- Dot size and bins are automatic. Quantum XL computes one shared bin interval across all selected columns so their dots align; there is no manual bin setting. See Math Details for the exact rule.
- Dot scaling on large data: when the data would need too many dots, one dot represents several observations and the chart shows a red note, "Note: Dots are scaled. Single dot represents maximum N observations."
- A maximum of 100 charts is produced; selections that would exceed that stop with a message.
There is no task pane for Dot Plot; to change anything after creation, run the tool again.
