Displays an interactive histogram view with different viewing options.The interactive histogram supports hiliting and the changing of the x axis and aggregation column on the fly.
The user can change the following view properties on the fly:
The Invalid_values bin contains values that can not be assigned to a regular bin e.g. NaN for a double value. The bin is displayed by default if the selected binning column contains an invalid value in the input table. To hide it go to the "Bin settings tab" of the node view and deselect the "Show invalid value bin" option.
All automatically created bins, with exception to the first one, are left open intervals (a,b] where a is excluded and b is included in the interval. To cover all values the first interval is a closed interval [a,b] where a and b are included. In order to provide nicer bin intervals the left border is set to 0 if possible.
Please note: This node caches all data in the main memory to provide interactive functions. If you plan to visualize extremely large datasets the non interactive "Histogram" node may be better suited.
Only columns with a valid domain are available in this view. To set the domain use the DomainCalculator or ColumnFilter node!
