Please help me. I want to show all at one place.

You can't accomplish what you are trying to do. Especially with scale = scale.none . Your BB will not match the chart candles because of this and because the volume will establish the range of the script's scale which won't remotely line up with your candles. You will need to have them as separate scripts with separate scales. The BB/MA using the chart's scale and another script with scale.none to put your volume on the bottom of the chart.
