How to display Hiding or Minimizing Chart

[madhubabum]

Hi all

I have declared 2 Variables Like

LET vMinDate = NUM(Date#('2014-01-01', 'YYYY-MM-DD'));    //FY13 and onward

LET vMaxDate = NUM(Date#('2016-12-31', 'YYYY-MM-DD'));   

Note : If i give LET vMaxDate = NUM(Date#('2015-12-31', 'YYYY-MM-DD')); 

Then the chart will be displayed other wise the chart will be minimized (Hiding)

So , How can we display the chart
