Color Histogram JavaScript Color

[mauuuuu5]

Hi everyone, I am trying to add color categories to the JavaScript Histogram but I am unable to do so. The node “Interactive Histogram Local” can add the colors based on a nominal column but due to the “real” data characteristics I need to bin based on Sample quantiles.

Thank you

Hello @mauuuuu5,

don’t think this is done automatically as in Interactive Histogram Local node. However workaround using Bar Chart node with logic outlined in this topic will hopefully be good enough:

How to Create Stacked Bar Chart

I have the following data. [image] How do I create a stacked bar chart, and customise the colour so that it looks like this? (Tried using Bar Chart node, but couldn’t figure out how.) [image] Attached data. Thanks. data.xlsx (10.5 KB)

Additional action for you to take is to use Auto-Binner node to get your bins based on sample quantiles as desired. This column will then be Category column in Bar Chart node’s configuration. Take a look, give it a try and if you’ll need workflow example drop me a message.

Hi Ivan thank you for your help, I managed to make a some kind of group chart not an histogram, but still I want to share the workflow

Thank you

Hello @mauuuuu5,

great! You can also share/upload workflows to KNIME Hub if you think others might benefit from it as then there are easier to find and more accessible.
