There are times where based on certain variables A user would like to see/not see certain objects in Canvas.
For eg. a pie chart showing revenue distribution by products across 12 months is shown on canvas, but the user wants to look at a detailed drilldown on a particular month across multiple product categories in a bar chart. He would like to replace the pie chart with the new detailed bar chart.
Currently Canvas can show only one object in the allotted frame and cannot dynamically change the object based on user input.
Thanks for the idea. We have recently shipped this in the latest release of Jedox. Please check it out and tell us what you think!
