@aliciaxuu welcome to the KNIME forum. You could take a look at this example and see if you can adapt it:

Barchart with Labels

@masgo I do not think there is a KNIME node you can use out of the box. But since the KNIME Python extension has matplotlib (and seaborn) integrated you can easily employ ChatGPT to let it write a suitable code. You could also warp that with a data app in order to make it interactive. It will require a little bit back an forth with the code but in the end it should work: [image] kn_example_python_graphic_bar_chart_percentage_change.knwf (131.4 KB)
