Properties
- boundedDates ↔ List
-
Values for use with panEdgeFraction, which limit how far outside the
graph's data boundaries it can be panned (
[minDate, maxDate]).getter/setter pair - boundedValues ↔ List
-
Values for use with panEdgeFraction, which limit how far outside the
graph's data boundaries it can be panned (
[minValue, maxValue]).getter/setter pair - cancelNextDblclick ↔ bool
-
Disable zooming out if panning.
getter/setter pair
- dateRange ↔ num
-
The range in second/value units that the viewport encompasses during a panning operation.
getter/setter pair

getter/setter pair
- dragDirection ↔ num
-
Indicates the current drag direction.
getter/setter pair
- dragEndX ↔ num
-
Drag start X-axis pixel coordinates.
getter/setter pair
- dragEndY ↔ num
-
Drag end Y-axis pixel coordinates.
getter/setter pair

getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- initializeMouseDown ↔ InteractionModelFunc
-
We cover iframes during mouse interactions.
getter/setter pair
- initialLeftmostDate ↔ num
-
The value on the left side of the graph when a pan operation starts.
getter/setter pair
- is2DPan ↔ bool
-
If so, is that pan 1- or 2-dimensional?
getter/setter pair
- isPanning ↔ bool
-
Is this drag part of a pan?
getter/setter pair
- isZooming ↔ bool
-
Tracks whether the mouse is down right now
getter/setter pair
- prevDragDirection ↔ num
-
Previous drag direction.
getter/setter pair
- prevEndX ↔ num
-
Previous drag end X-axis pixel coordinates.
getter/setter pair
- prevEndY ↔ num
-
Previous drag end Y-axis pixel coordinates.
getter/setter pair
- px ↔ num
-
Top corner of the canvas, in DOM coords.
getter/setter pair
- py ↔ num
-
Left corner of the canvas, in DOM coords.
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- tarp ↔ DygraphIframeTarp
-
We cover iframes during mouse interactions.
getter/setter pair
- xUnitsPerPixel ↔ num
-
The number of units each pixel spans (this won't be valid for log scales).
