Histogram (legacy)

Displays a histogram view with different viewing options.

The user can change the following view properties on the fly:

1. Aggregation method (count, summary, average)
2. Bar size
3. Show empty intervals
4. Show missing value bar
5. Layout
6. Zooming
7. ...

The bars are colored in proportion to the aggregation value. Hiliting is not supported.

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, except 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.

This view is particularly well suited for extremely large datasets. For more interaction and hiliting support use the "Interactive Histogram" node.

Only columns with a valid domain are available in this view. To set the domain use the DomainCalculator or ColumnFilter node!
