Violin Plot (Plotly)

A Violin plot built with the Plotly.js library. This plot is used to visualize multiple plots simultaneously across various categories or group-memberships. The plot displays a traditional boxplot with quartile notations for each group as well as single points for outliers in the data set. It also conveniently displays a histogram of the data distribution. This node also provides real time statistic values when you "hover" over a particular violin, such as mean, median, and more.

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 .
