MQL5 - using indicator without graphical representation

 

i want to use iBands in my EA without drawing results on the chart. I want to do that because i already programmed keltner function inside the EA and im handling drawing of the gfx myself. I want the same exact for bollinger, but since iBands is already here i would like to use it and handle drawing in exact same way as with keltner (my own graphics function, so that drawing of both indicators is done the same way). is there an easy way to disable automatic drawing of i-indicators?
