For passing the input parameters on the dashboard to the child report, you need to pass the values of dashboard variables in the URL of the child report along with the parameter from the chart.
For this, at the report level in the JS Editor, use the below given script. Here what we have written is that we have specified the dashboard variables and on-click even the child reports opens. All the multiple dashboard variables gets added to the child report in URL so that it shows data for all the filtered value. Herein we are referencing Dashboard.getVariable and this API only works at dashboard level, so when you use this at dashboard you will see:
var viz_Options = c.get("viz_Options");
onclick: function (d, i)
var start = Dashboard.getVariable('StartDate');
var end = Dashboard.getVariable('EndDate');
var users = Dashboard.getVariable('userstats_UserID');
var lead = d.name;
Replace the variable names in the above code with the variable names that you are using on your dashboard.
Also, the above code will open the child report in new tab. If you want to open it in the same frame, replace ‘_blank’ by ‘_self’.
