PMI Triangle Scatter Plot

Vernalis PMI-extension for KNIME Workbench version 1.28.2.v202101281353 by Vernalis (R&D), UK

This node plots a basic PMI Triangle scatter plot, in which each input row is represented by a symbol on the plot within the PMI Bounds box. The symbol shape, size and colour can be controlled by the appropriate 'Manager' nodes applied to the input table.

This node was developed by Vernalis Research. For feedback and more information, please contact knime@vernalis.com

General Plot Options

Type of Image
The type of the created image can either be png or svg. PNGs are mostly smaller, SVGs provide details about plot and the possibility to be changed individually
Title of Graph
The title of the graph shown above the generated image. If the title is not activated, no title will be shown
Width of Image (in pixel)
The width of the generated image, not the plot width
Height of Image (in pixel)
The height of the generated image, not the plot height
Background Colour
The color of the background of the plot. Hence this color is used for the empty space in a plot
Plot background Alpha
The transparency of the plot background can be modified using an additional alpha value. An alpha value of 1 does not change the background transparency. Decreasing the alpha value will increase the plot background transparency
Scale Font Size
Factor changes the font sizes within the JFreeChart view. A value greater the 1 increases all view fonts, a value between 0 and 1 decrease them

Input Ports
