Hi,
I have a R View plotting the graph in the output port.
How do I render that output port in web portal?
Is Quick Form File Download node the correct node to use to display something at the web portal?
What is the input? We have to transform the knime.out variable to a filepath variable first?
Thanks,
Simon
Hi Simon,
for this you need to add the Image Output node after the R-View node.
This can be directly connected to the R View node.
Best, Iris
Hi Iris,
Thanks for your reply!
I did exactly that - but the image doesn't show in the web portal.
KNIME client 3.4
KNIME server the latest version - 4.4.1
Attached is the workflow.
Please help.
Simon
