Hi @Tengxiao ,

Welcome to the Forum!

Could you please confirm which node you are using to display the bar chart?

I tried creating a workflow using the Bar Chart node, with some dummy data and was able to visualize both negative and positive values on the chart. I have attached the workflow for your reference. Please let me know if this resolves your issue.

hi @k10shetty1 ;
Thank you for your reply;
First, i use the node Bar chart which belongs to JavaScript. And i found your workflow was using the node bar chart which was from KNIME labs.
Second, how can we configure the node(KNIME labs) to visualize values on the chart. i don’t found the option.

hi @k10shetty1 ；
I think it was the KNIME version issues, i have solved this problem by update the KNIME to V4.7.8
Thank you very much.
