Try something like:

   Vars: StartDay(0), RSI_Val(0);

   if CurrentBar = 1 then begin
      StartDay = JulianToDate(LastCalcDate - 20);
   end;

   RSI_Val = RSI(Close, Length);

   if Date >= StartDay then begin
      Plot1(RSI_Val, "1");     
      Plot2(.... , "2");     
      Plot3(.... , "3");
   end;

Be sure to use variables to calculate the value of RSI, etc., outside
the plotting conditional code to make sure the values are properly
initialized.

You will need to plot points rather than lines if you only want it to
plot during the above interval.
