Re: How to change the chart type on click of the button
I'm not sure how to achieve your requirement. In Qlikview we can do it by Fast Change option or also by assigning Buttons which has actions for show and hide object based on object ID.
In Qlik Sense we're limited with Conditional expression.
The screenshot which you provided doesn't explain how it can be achieved (after doing extensive research many of the developers and experts here say it cannot be achieved, can't hide an object).
We do not have this feature in Qlik Sense. I've already tried show/hide using object ID and it doesn't work. So your best option is use as a container as I've said previously. Qlik Sense is more User friendly and for developers not everything is same as Qlik View, we're limited.
Maybe it can be achieved by Mashups? I'm not sure... You can try that.
