9.6.1 The (Plot Details) Box TabPDDialogBoxTab
Type
Choose from Box, Data, Box + Data Overlap, Box(Right) + Data(Left), Box(Left) + Data(Right), Bar, Bar + Data Overlap, Bar(Right) + Data(Left), Bar(Left) + Data(Right), Half Box(Right) + Data(Left) or Half Box(Left + Data(Right) in the Type dropdown List.
By default, the box chart displays only a Box  not the (binned) Data. You can display the box and binned data, or only the binned data. The binned data is saved in a Binn worksheet. This worksheet contains the bin centers, counts, cumulative sums, and cumulative probability.
 To access the Binn worksheet, rightclick on the box chart and select Go to Bin Worksheet from the shortcut menu.
Note that when you select a display that includes the binned data, the Plot Details Data tab becomes available for editing the bins and overlaying a distribution curve.

 No Box
 Box
 Ishaped Box: Just show horizontal lines for the box.
 Diamond Box: Show the box shape as a diamond.
 Notched Box: This is a useful variation of the boxandwhisker chart. Notches on the box represent the confidence interval about the median value. If notches of two box plots do not overlap, we can assume that the two median values differ at the 95% confidence level (McGill, R., J.W. Tukey, and W.A. Larsen. 1978. Variations of Box Plots. The American Statistician. 32. 12).
 95% LCI of Median: Median  1.58 * (IQR/sqrt(n))
 95% UCI of Median: Median + 1.58 * (IQR/sqrt(n))

Range

 SE (standard error)
 SD (standard deviation)
 Perc 25, 75 (25/75th percentiles),

Note: When the box Style is set to No Box or Notched Box, the Range dropdown list will be grayed out .

Coef

Select or type in a factor by which to expand the box (default is 1). This can be useful, for instance, in combination with the SD option in the Range dropdown list to show how data points are distributed within 2 or 3 standard deviations of the mean.
Note: When the box Range is set to Perc 25, 75 and Perc 10, 25, 75, 90, the Coef combo box will be grayed out.

P

Specify percentiles value for box range in this combo box. The P value can be set between 0 to 100. When it is set to 30, that means the box range is 30% to 70%.
Note: P combo box is only available when Custom Percentile <P, 100P> is selected in Range dropdown list.

Box Width by Parameter

Specify whether to control the box width by the column label row in the source column. Choose the parameter in the Box Width(%) list.

Box Width(%)

Select or type a factor to control the box width in the combo box. This is a percent and only values from 0 to 100 are acceptable.
When the Box Width by Parameter check box is selected, the box width is controlled by the column label row listed in this dropdown. The parameters include: Long Name, Units, Comment, Sampling Interval and Parameter.

Scaling Factor

Type or select a value by which to scale the associated parameters (default is 1). For example, select 0.25 to scale each parameter value by a factor of 1/4.

Whisker
Range

Use the Range dropdown list to determine the quantity displayed by the whiskers (or choose No Whiskers).
Choose from No Whiskers, 1090th, 595th, 199th, SD (standard deviation), SE (standard error), Outlier, MinMax, Constant, Custom Percentiles <P, 100P> or Confidence Interval.

P

Specify percentiles value for whisker range in this combo box. The P value can be set between 0 to 100. When it is set to 30, that means the whisker range is 30% to 70%.
Note: P combo box is only available when Custom Percentiles <P, 100P> is selected in Range dropdown list.

Probability(%)

Specify the confidence levels for which the confidence intervals will be computed in this combo.
Note: Probability combo box is only available when Confidence Interval is selected in Range dropdown list.

Coef

Select or type a value n into the Coef combo box to expand the whisker by a factor of n.

Direction

This option is only available, when Box Style = No Box.
Specify how to show the whisker on the plot.
 Plus: Only show the upper whisker.
 Minus: Only show the lower whisker.
 Both: Show both upper whisker and lower whisker.

Note that if you select Outlier from the Range dropdown list and accept the default Coef value of 1.5, whisker length will be determined by the outermost data point that falls within upper inner and lower inner fence (a Coef = 3 would be determined by the outermost data point that falls within the upper outer and lower outer fences).
Upper Inner Fence = 75th Percentile + (1.5 * Interquartile Range)
Lower Inner Fence = 25th Percentile  (1.5 * Interquartile Range)
Bar
Represent

Specify the value that the height of the bar represents.
Choose from Mean, N(number of data), Median, Min, Max, Sum, SD (standard deviation), SE (standard error).

Bar Width by Parameter

Specify whether to control the box width by the column label row in the source column. Choose the parameter in the Box Width(%) list.

Bar Width(%)

Select or type a factor to control the box width in the combo box. This is a percent and only values from 0 to 100 are acceptable.
When the Box Width by Parameter check box is selected, the box width is controlled by the column label row listed in this dropdown. The parameters include: Long Name, Units, Comment, Sampling Interval and Parameter.

Scaling Factor

Type or select a value by which to scale the associated parameters (default is 1). For example, select 0.25 to scale each parameter value by a factor of 1/4.

Error Bar
Range

Specify whether link the Xaxis to a real scale. By default, it set to Auto that does not link to the real axis scale. In this dropdown list, these column labels can choose as the parameter to control the scale: Long Name, Units, Comment, Sam
Data and Whisker Drawing Options
Draw Data on Top of Box/Bar

This option available for Box + Data Overlap or Bar + Data Overlap options. Data symbols will be drawn overlaying the box or bar.

Draw Whisker/Error Bar on Top of Data

This option is available when the previous option Box + Data Overlap or Bar + Data Overlap is selected. This option and the Draw Data on Top of option above, interact as in the following example:

Outliers

Data points that lie outside of the whiskers are considered to be outliers. Subsequently, selecting the Outliers check box will display these outliers with individual data points being represented using the settings on the Symbol tab.

Outliers in Line

Specify whether the outliers of box plot align in a line in the center of the box plot.

Labels
Box

Show the labels of the top, the median and the bottom lines mext to the box plot.
For example, when you select Perc 25, 75 from the Range list for Box, the labels for the 75th percentile, median and 25th percentile, will display in the graph.

Whisker

Show the label of upper and lower whisker next to the box plot.

Mean

Show the label of mean next to the box plot.
The location of the mean can be marked by symbols (Percentile tab) and/or horizontal lines (Lines tab). You must enable mean display on at least one of these tabs before you can choose to label the mean.
Beginning with Origin 2020, you can mark the location of the mean using a horizontal line, without showing a box (e.g. on the Box tab, set Type = Data) but you will have to enable Type = Box momentarily, in order to check the Labels boxes. Once checked, you can disable box display and your horizontal line will remain labeled.

Median

Show the label of median next to the box plot.
The location of the median can be marked by symbols (Percentile tab) and/or horizontal lines (Lines tab). You must enable median display on at least one of these tabs before you can choose to label the median.
Beginning with Origin 2020, you can mark the location of the median using a horizontal line, without showing a box (e.g. on the Box tab, set Type = Data) but you will have to enable Type = Box momentarily, in order to check the Labels boxes. Once checked, you can disable box display and your horizontal line will remain labeled.

Show

Specify to show the Value, Percentile or both for the Box/Whisker/Mean Value Labels.

The labels format can be customized in the Label tab .
