If I click a mark on the chart after deploying the chart to the web portal, can I link the charts so that the information of the clicked mark is filtered from other charts? like tableau
Hello Isj,
Thank you for your question. Yes, it is easily possible to create an interactive dashboard in KNIME using JavaScript views. You have to select the option “Subscribe to selection events” in the interactivity tab of the JavaScript based view. If checked, the view reacts on notifications from other interactive views that the selection has been changed. You can also find more information in this video: https://www.knime.com/knime-introductory-course/chapter5/section3/composite-views
Have fun creating interactive dashboards,
Jeany
