JFreeChart Bar

KNIME Analytics Platform
1

Hello, I have problems using Bar Chart (JFreeChart).I have already solved some minor issues with Knime but still beginning.

When I use columns as sex or departement everything works fine. But when I use columns as: ZIP-code or ICD-codes ( international classification of diseases, which looks e.g. M72.0) it doesn't work. Are there limitations in maximum number of values, which could be counted, in one column ? Cannot find any limitations in the Node Description,

Thanks for your help

Hi Peter,

 

this is most probably a problem in the domain. The bar chart uses the previously calculated set of possible values. This is automatically limited to 60.

You can add the "Domain Calculator" node before the Bar Chart view, in this node you can change the number of possible values.

 

Best, Iris
