188.8.131.52 The (Column Properties)Categories Tab
The Categories tab of the Workbook Column Properties dialog allows you to customize the categorical properties of a particular column. It is only accessible when current column is Set As Categorical.
And the same controls in this tab can be accessed by double clicking on the Categories column label row.
If the column is Set As Categorical, the Missing Values by default will be excluded from the categorical map. To include missing values as categories, you have to set system variable @cats=0 first and then right click on that column and uncheck Set As Categorical. Right click on that column again to check Set As Categorical so that missing values will be taken into account now.
Customize Categories (Add, Delete, Set Arbitrary Order)
Checking this box allows you to customize categories: Add, delete or arbitrarily order categories. When cleared, categories are dynamically generated from column data.
Available when the Customize Categories (Add, Delete, Set Arbitrary Order) check box is cleared.
Categorical order determined by order of first appearance in column.
Sort categories in ascending order.
Sort categories in descending order.
Notes on Sort Order
Sort order determines plotting order. In the following two examples, column B(Y) contains numeric data and column A(x) is Set as Categorical and sorted in Ascending order. Note that sorting does not sort worksheet data; rather it sorts categories for plotting.
Prior to Origin 2017 SR1, categories in the second example (strictly numeric data) would have been sorted alphabetically, resulting in a different plotting order as seen in the following:
Display the category elements in current worksheet column and its current order.
The Category Index is assigned according to category sort order, or if unsorted, by the order in this Category list.
Beginning with Origin 2020b, you can toggle between display of Category and Category Index in the worksheet column by clicking the Show Category Indices button on the worksheet page-level Mini Toolbar.
