PURPOSE
Create Stem-and-Leaf Plot
INSTALLATION
Download the Stem_and_Leaf_Plot.opx, and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps Gallery window.
OPERATION
Follow the steps below to set up and create your graph:
- Input Data: Enter one numeric column to plot.
- Group (Optional): Enter a column of data that defines groups. Origin will display a separate plot for each unique value in the Group column.
- Leaf Unit (Optional): Enter a value to specify which decimal place the leaf values represent. If no value is specified, Origin will calculate and select an appropriate one.
- Auto Split Stem: Select this option to introduce a break in the leaves at 5 automatically. This will help create a stretched stem-and-leaf plot when needed.
- Max Number of Leaves per Stem: Specify the maximum number of leaves (default = 50) to be displayed for any given stem.
- Auto Trim Outliers: Select to remove outliers from the main plot. Outlier values are shown on lines labeled Outliers. Origin defines Outliers > 1.5 * IQR.
- Show Matching Histogram: Select to generate a histogram that matches the stem-and-leaf plot.
- Output Report: Specify the output location for the stem-and-leaf plot.
