ChartScale

Controls how chart series are positioned horizontally and vertically. Other configurations like: inverse, lockRatio etc.

Property	Description	Type
auto	Auto scale will always fit whole chart series in viewport.	boolean

inverse	Inverses the Y scale vertically.	boolean
autoScaleOnCandles	Do auto scale (even if it's not enabled in config) after instrument change.	boolean
autoScaleDisableOnDrag	When dragging chart under specific angle - will automatically disable auto-scale.	AutoScaleDisableOnDrag
zoomSensitivity	0..1 ratio of full viewport; 0.5 = middle, 0.75 = 3/4 of viewport	number
defaultViewportItems	Defines how much items (candles) will be in viewport when chart applies basic scale	number
keepZoomXOnYAxisChange	Adjust x viewport when y-axis width is changed, so x zoom remains the same	boolean

When dragging chart under specific angle - will automatically disable auto-scale.

Property	Description	Type
enabled		boolean
edgeAngle	The angle of mouse movement. Default - Math.PI / 9.	number
