I am unable to execute the java script based pie and stacked charts, shows the attached error.
I am running a windows version of Knime latest version through Wine and I suppose my browsers are configured to run directly using Ubuntu dependencies whereas Knime is using Windows features through Wine.
The error shows “Retrieving image from view failed: Error retrieving image: Chrome driver was not initialized. Could not retrieve image.”
Also you could try and convert the image to PNG and try to save that since the default outcome seems to be SVG (of course if that is not working the conversion will also not work).
