This is for filter or list box. But my client asking for the below
This has to be appear in the graphs of the dashabord. For example I have Bar Chart and Pie Chart in a dashboard. If I select one bar in the bar chart other bars should fadeout and the corresponding slice of pie should be shown in the pie chart. I want the same funda in viseversa.
I dont know about Qlik Sense - but in QlikView it could be possible in some cases but might be a bit tricky.
E.g. the basic QV logic is: if you select something - it filters the datamodel in the background - so its not simply showing/not showing bars - its actually filtering out. If you click on a piece of pie chart showing 15% - it will most probably show 100% afterwards as you filtered on these particular cases.
Once I read here somewhere about a clever approach where you actually use a listbox to highlight certain bars. The idea was that you have a background color condition: e.g. you click on listbox value 'March 2015' and then the backgroundcolor of all the other bars turn white (invisible) or grey and the particular bar is shown in bright green...that might be a way to solve this without overcomplicating the expressions/dimensions in your chart.
You can try this by using the Background Color of the Expression, use GetFieldSelections() to get the selected values and give different background color for the remaining bars which are not selected conditionally.
Or you can use the Set Reference option which comes with the default qlikview app.
Right click on the chart and click on Set Reference option, now whatever the values you selected it will be shown other values are fadeout.
