Select tooltip columns
Select columns that should be put on a tooltip when the mouse cursor is over a data point. By default, all columns are shown, if the table contains less than 21 columns, and no columns are shown, if a table contains 21 columns or more.
One of the unique exploratory data analysis-related features of Datagrok is the ability to interactively visualize group of rows on an arbitrary viewer when the mouse is over a visual that represents multiple rows.
Here are some examples of such visuals:
- Bars in a histogram
- Bars in a bar chart
- Segments and legend items in a pie chart
- Category labels in a trellis plot
- Rectangular areas in a tree map
- Nodes and edges in a network diagram
- Words in a word cloud
- Categories and histogram bins in a filter
You can choose any viewer as a tooltip for the so-called "mouse-over rows". To do that, add a viewer of interest (such as scatter plot), customize the settings accordingly, and then select Tooltip | Use as group tooltip. After that, once a mouse cursor gets over the segment that represents multiple rows, a scatter plot containing only mouse-over rows will be shown in a tooltip.
"Reset group tooltip" removes group tooltip.
