Line Plot (Labs)

A line plot visualization node. The view can be accessed either via the “interactive view” action on the executed node or on KNIME WebPortal.

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 fast in the desired shape.

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

Note, this node is currently under development. Future versions of the node might have improved or changed functionality.

Options

Horizontal dimension

Defines the column that contains the values for horizontal dimension.

Vertical dimension

Defines the columns that contain the values for vertical dimension.

Max rows

Numerical value that restricts the number of rows used for this visualization.

Title

The title of the graph shown above the generated image. If left blank, no title will be shown.

Horizontal axis label

The label for the horizontal axis. If left blank, no label will be shown.

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.

Line thickness

Numeric value that defines the line size.

Show data point markers

When checked, markers show the location of each data point.

Marker size

Numeric value that defines the marker size.

Date & time format

Format that determines how date & time values should be displayed. At the moment only local date & time and local date types are supported. In general it is done with putting string templates of the individual pieces in curly brackets like '{yyyy}-{MM}-{dd}'. Refer to the echarts documentation for further information on how to format the values.

Enable image download

When checked, an image of the chart can be downloaded by clicking the image download button in the view.

Enable data zoom

When checked, zooming in the chart is enabled.

Show tooltip

When checked, hovering over a line will show information about the data.

Use axis range from

Choose if the axis range of the value axis should be calculated automatically by the charting framework or the domain range should be used. You might need to use a Domain Calculator or Edit Domain node before this node.

Enable animation

When checked, the animation of the graph is active.
