Allows you to set the starting point of the arrow to either a predetermined [x, y] coordinate on the chart, or to a charted value.

Attribute	Type	Info
hook	String	Demo Sets the arrow's starting point to that of a charted value. The plot value refers to the set of values in a series, and the index refers to the specific value within that series. For example, `node:plot=0,index=10` sets the starting point of the arrow at the 11th value within the 1st set of values in the series. Note that 0 refers to the first value or set of values, with 1 being the second value or set of values, and so on. "node:index=4" \| "node:plot=0,index=1" \| ...
