- default: 18
- desc: Width of the div which contains the y-axis label. Since the y-axis label appears rotated 90
- degrees, this actually affects the height of its div.
- tags:
- - chart labels
-
-- name: ylabel
- type: String
- default: null
- desc: Text to display to the left of the chart's y-axis. You can supply any HTML for this value, not
- just text. If you wish to style it using CSS, use the 'dygraph-label' or 'dygraph-ylabel' classes.
- The text will be rotated 90 degrees by default, so CSS rules may behave in unintuitive ways. No
- additional space is set aside for a y-axis label. If you need more space, increase the width of
- the y-axis tick labels using the yAxisLabelWidth option. If you need a wider div for the y-axis
- label, either style it that way with CSS (but remember that it's rotated, so width is controlled
- by the 'height' property) or set the yLabelWidth option.

-- name: connectSeparatedPoints
- type: Boolean
- default: false
- desc: Usually, when Dygraphs encounters a missing value in a data series, it interprets this as a

+ type: Integer
+ desc: When displaying numbers in normal (not scientific) mode, large numbers will
+ be displayed with many trailing zeros (e.g. 100000000 instead of 1e9). This
+ can lead to unwieldy y-axis labels. If there are more than maxNumberWidth
+ digits to the left of the decimal in a number, dygraphs will switch to scientific
+ notation, even when not operating in scientific mode. If you'd like to see
+ all those digits, set this to something large, like 20 or 30.
- name: sigFigs
- type: Integer
- default: null
- desc: By default, dygraphs displays numbers with a fixed number of digits after the decimal point.
- If you'd prefer to have a fixed number of significant figures, set this option to that number
- of sig figs. A value of 2, for instance, would cause 1 to be display as 1.0 and 1234 to be displayed
- as 1.23e+3.

- name: valueFormatter
- type: function(num or millis, opts, dygraph)
- default: null
- desc: Function to provide a custom display format for the values displayed on mouseover. This does
- not affect the values that appear on tick marks next to the axes. To format those, see axisLabelFormatter.
- This is usually set on a per-axis basis. For date axes, you can call new Date(millis) to get a
- Date object. opts is a function you can call to access various options (e.g. opts('labelsKMB')). Default
- formatter will depend on the type of your data.
