Summary Panel
The summary panel displays a vertical scrolling list of all of the column names and an icon representing their respective type. It displays a sparkline histogram or frequency table of that column’s data, and also displays the amount of missing data as both an inline bar graph and an increasing percentage. If you click on the caret symbol for a column, it will expand to show additional summary statistics and a larger sparkline.
Depending on the size of the dataset, when first opening the Data Explorer or using its features (like scrolling, filtering, or sorting), you may see loading indicators in the summary pane and in the bottom left corner of the window:
The summary sparkline charts and missing data indicator display tooltips when hovered over:
If you hover over the data type indicator next to the column name, you will see a tooltip showing the name of the column’s data type:
If the column is labelled, the tooltip will include the label.
Double clicking on a column name will also bring the column into focus in the data grid, allowing for quickly navigating wider data.
The summary panel can be collapsed by dragging the grid and summary panel divider to the edge or by clicking on the collapse button after hovering over the divider.
The summary panel can also be placed on the left or right side of the Data Explorer via the Layout control.
You can change the default settings for either dataExplorer.summaryCollapsed or dataExplorer.summaryLayout in Positron’s settings:
