Field Detail

AxisLabelFormatter

Defined in: dygraph-internal.externs.js.

DRAG_EDGE_MARGIN

You can drag this many pixels past the edge of the chart and still have it be considered a zoom. This makes it easier to zoom to the exact edge of the chart, a fairly common operation.
Defined in: dygraph-interaction-model.js.

DygraphDataArray

Defined in: dygraph-internal.externs.js.

DygraphInteractionContext

Defined in: dygraph-types.js.

OPTIONS_REFERENCE

Defined in: dygraph-options-reference.js.

PREFERRED_LOG_TICK_VALUES

This is a list of human-friendly values at which to show tick marks on a log scale. It is k * 10^n, where k=1..9 and n=-39..+39, so: ..., 1, 2, 3, 4, 5, ..., 9, 10, 20, 30, ..., 90, 100, 200, 300, ... NOTE: this assumes that utils.LOG_SCALE = 10.
Defined in: dygraph-tickers.js.

TICK_PLACEMENT

The value of datefield will start at an even multiple of "step", i.e. if datefield=SS and step=5 then the first tick will be on a multiple of 5s. For granularities <= HOURLY, ticks are generated every `spacing` ms. At coarser granularities, ticks are generated by incrementing `datefield` by `step`. In this case, the `spacing` value is only used to estimate the number of ticks. It should roughly correspond to the spacing between adjacent ticks.
Defined in: dygraph-tickers.js.

Ticker

Defined in: dygraph-tickers.js.

TickList

Defined in: dygraph-tickers.js.

ValueFormatter

Defined in: dygraph-internal.externs.js.

Method Detail

annotations()

Current bits of jankiness: - Uses dygraph.layout_ to get the parsed annotations. - Uses dygraph.plotter_.area It would be nice if the plugin didn't require so much special support inside the core dygraphs classes, but annotations involve quite a bit of parsing and layout. TODO(danvk): cache DOM elements.
Defined in: annotations.js.

axes()

Draws the axes. This includes the labels on the x- and y-axes, as well as the tick marks on the axes. It does _not_ draw the grid lines which span the entire chart.
Defined in: axes.js.

chart_labels()

Defined in: chart-labels.js.

distanceFromChart(event, g)

Returns the number of pixels by which the event happens from the nearest edge of the chart. For events in the interior of the chart, this returns zero.
Defined in: dygraph-interaction-model.js.

Parameters:
event
g

{number} numDateTicks(start_time, end_time, granularity)

Compute the number of ticks on a date axis for a given granularity.
Defined in: dygraph-tickers.js.

Parameters:
{number} start_time
{number} end_time
{number} granularity: (one of the granularities enumerated above)

Returns:: {number} (Approximate) number of ticks that would result.

{number} pickDateTickGranularity(a, b, pixels, opts)

Determine the correct granularity of ticks on a date axis.
Defined in: dygraph-tickers.js.

Parameters:
{number} a: Left edge of the chart (ms)
{number} b: Right edge of the chart (ms)
{number} pixels: Size of the chart in the relevant dimension (width).
{function(string):*} opts: Function mapping from option name -> value.

Returns:: {number} The appropriate axis granularity for this chart. See the enumeration of possible values in dygraph-tickers.js.
