Line Plot

The view can be accessed either via the “Open view” action on the executed node or on KNIME Hub.

In the node configuration, you can choose the size of a sample you want to display and enable certain controls, which are then available in the view.
This includes the ability to choose different columns for x and y or the possibility to set a title.
The configuration also offers a preview of the view, which should help to get the line plot in the desired shape quickly.

Since missing values as well as NaN (not a number) or infinite values cannot be displayed in the view, they will be omitted.

Title
The title of the graph shown above the generated image. If left blank, no title will be shown.
Value axis limits
Choose if the axis range of the value axis should be calculated automatically by the charting framework, taken from the domain range or set manually. You might need to use a Domain Calculator or Edit Numeric Domain node before this node.

Vertical axis label
The label for the vertical axis. If left blank, no label will be shown.
Vertical axis scale
Choose if the vertical axis should be displayed in linear or logarithmic scale.
