Trying to create a Indicators on screen Show/hide buttons. Please help

[BearIng.Virgin]

I tryin to easy show/hide indicators on the chart window, better that switch templates, I think. I did the interface and the buttons for each one, this example is with easy moving averages, but I think can be used for Ichimoku, BBands, etc, please check on the screen shot.

I have the buttons done, but my problem is the linking Boolean variables to define the show/hide, as well as the logic to execute it. Please check on my code, I tied with some variables but cant get linked batwing OnCalculate and OnChartEvent

Thank you

Try as follows;

for (int i = limit - 1; i >= 0; i--)
{
   //Calculates each MA
   Label1Buffer[i] = iMA(NULL, 0, 14, 0, 0, 0, i);
   Label2Buffer[i] = iMA(NULL, 0, 28, 0, 0, 0, i);
}

if (id == CHARTEVENT_OBJECT_CLICK && sparam == "MA14Button")
{
   SetIndexStyle(0, DRAW_LINE, STYLE_SOLID, 1, clrWhite);
   SetIndexStyle(1, DRAW_NONE, STYLE_SOLID, 1, clrNONE);
}

if (id == CHARTEVENT_OBJECT_CLICK && sparam == "MA28Button")
{
   SetIndexStyle(1, DRAW_LINE, STYLE_SOLID, 1, clrRed);
   SetIndexStyle(0, DRAW_NONE, STYLE_SOLID, 1, clrNONE);
}

You are awesome!!!

 I wanted to show both of them if the case, not only switch one to other, I took your advise and got this. works awesome 

Thank you!!

 if (id == CHARTEVENT_OBJECT_CLICK && sparam == "MA14Button")
            { switch (MA14_Ind)
            {   case (true):  SetIndexStyle(0, DRAW_LINE, STYLE_SOLID, 1, clrRed); MA14_Ind=false; break;         
                case (false): SetIndexStyle(0, DRAW_NONE, STYLE_SOLID, 1, clrNONE); MA14_Ind=true; break;
            } 
            }

   if (id == CHARTEVENT_OBJECT_CLICK && sparam == "MA28Button")
             { switch (MA28_Ind)
            {   case (true):  SetIndexStyle(1, DRAW_LINE, STYLE_SOLID, 1, clrWhite); MA28_Ind=false; break;         
                case (false): SetIndexStyle(1, DRAW_NONE, STYLE_SOLID, 1, clrNONE); MA28_Ind=true; break;
            } 
            }
