2D Density Plot (Plotly)

A 2D Density plot with optional axis-based histograms built with the Plotly.js library. This plot is useful for exploring the distribution and density in a dataset. You can compare two features at a time and optionally display histograms with the linear distribution of each feature along the axis.

The node supports custom CSS styling. You can simply put CSS rules into a single string and set it as a flow variable 'customCSS' in the node configuration dialog. Current KNIME classes are NOT YET supported, so class names will have to be deduced from the view itself. We are hoping to support standard KNIME classes in an upcoming update.

Please note: the Plotly.js KNIME extension is currently in Labs. It is recommended that you handle missing values and normalize your data before using visualization nodes in this extension to improve performance. Please feel free to leave feedback and suggestions on our community forum here .
