Thanks @plagun98.
Having a look at your provided code sample I can't see anything that you've done incorrectly, and I can see the same behaviour as you show in the screenshot.

We would need to investigate further but I would assume that we are leaving space under the series because there might be a marker that we could want to drawn in that space. So the library might need a ignoreMarkersDuringAutoScaling option added to the PriceScaleOptions.

I'll mark this as a bug for now.

I met the same case, when I applied MACD histogram to candle chart in a single chart object, there came some gaps in both histogram and candle area.
