Reference line

This tutorial describes how to create and connect ReferenceLine to TimeSeriesWidget and apply it in various use cases.

# Create ReferenceLine

This example shows how to create a basic ReferenceLine and connect ReferenceLine to an axis associated with a curve (TimeSeriesLine) or TimeSeriesObject.

The Reference line value is defined as a y axis number.

# ReferenceLine with Fills

This example shows how to create and use ReferenceLine alongs with addFill in TimeSeriesWidget to add fills below or above a curve.

ReferenceLine can be created before hand, then connect with a curve (TimeSeriesLine) or TimeSeriesObject.

When a value passed as reference line value when calling addFill, TimeSeriesWidget automatically find the first connected ReferenceLine with the same value and fill up to the reference line.

# ReferenceLine with Groups

This example shows how to use ReferenceLine in TimeSeriesObjectGroup.

Just like connecting ReferenceLine with a curve (TimeSeriesLine) or TimeSeriesObject.
It works similarly as long as we connect the reference line with one of the curve added in TimeSeriesObjectGroup.
