Sets the coordinate values corresponding to the rangebreaks. An alternative to `bounds`. Use `dvalue` to set the size of the values along the axis.

Sets the size of each `values` item. The default is one day in milliseconds.

Determines where ticks and grid lines are drawn with respect to their corresponding tick labels. Only has an effect for axes of `type` *category* or *multicategory*. When set to *boundaries*, ticks and grid lines are drawn half a category to the left/bottom of labels.

Determines where tick labels are drawn with respect to their corresponding ticks and grid lines. Only has an effect for axes of `type` *date* When set to *period*, tick labels are drawn in the middle of the period between ticks.

Determines if the axis lines or/and ticks are mirrored to the opposite side of the plotting area. If *true*, the axis lines are mirrored. If *ticks*, the axis lines and ticks are mirrored. If *false*, mirroring is disable. If *all*, axis lines are mirrored on all shared-axes subplots. If *allticks*, axis lines and ticks are mirrored on all shared-axes subplots.

Determines whether long tick labels automatically grow the figure margins.

Determines whether or not spikes (aka droplines) are drawn for this axis. Note: This only takes affect when hovermode = closest

Sets the spike color. If undefined, will use the series color

Sets the width (in px) of the zero line.

Determines the drawing mode for the spike line If *toaxis*, the line is drawn from the data point to the axis the  series is plotted on. If *across*, the line is drawn across the entire plot area, and supercedes *toaxis*. If *marker*, then a marker dot is drawn on the axis the series is plotted on

Determines whether spikelines are stuck to the cursor or to the closest datapoints.

Sets the hover text formatting rule using d3 formatting mini-languages which are very similar to those in Python. For numbers, see: https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#d3_format And for dates see: https://github.com/d3/d3-time-format#locale_format We add one item to d3's date formatter: *%{n}f* for fractional seconds with n digits. For example, *2016-10-13 09:15:23.456* with tickformat *%H~%M~%S.%2f* would display *09~15~23.46*
