Line Chart (JFreeChart) Flow Variables

KNIME Analytics Platform
1

I am passing to the Line Chart (JFreeChart) node an array of strings of table column names the data for which I want to plot.  The column selection is made via a Column Filter quick form.

 

I am puzzled how I am to configure the Line Chart node to Include for graphing only the columns identified in the input flow variable containing the array of strings.  Which setting in the Flow Variable tab of the Line Chart node is to be changed to include the variable name for the array?

Hi Bradley,

unfortunately it is not possible to use an array as a flowvariable. 

However the outport of the column filter quickform only contains the remaining columns. Is this what you are looking for.

Best, Iris
