Specifies the maximum number of ticks for the particular axis. The actual number of ticks will be chosen automatically to be less than or equal to `nticks`. Has an effect only if `tickmode` is set to *auto*.

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

If "true", even 4-digit integers are separated

If *all*, all exponents are shown besides their significands. If *first*, only the exponent of the first tick is shown. If *last*, only the exponent of the last tick is shown. If *none*, no exponents appear.

Determines whether or not the tick labels are drawn.

If *all*, all tick labels are displayed with a prefix. If *first*, only the first tick is displayed with a prefix. If *last*, only the last tick is displayed with a suffix. If *none*, tick prefixes are hidden.

Same as `showtickprefix` but for tick suffixes.

Sets the thickness of the color bar This measure excludes the size of the padding, ticks and labels.

Determines whether this color bar's thickness (i.e. the measure in the constant color direction) is set in units of plot *fraction* or in *pixels*. Use `thickness` to set the value.

Sets the placement of the first tick on this axis. Use with `dtick`. If the axis `type` is *log*, then you must take the log of your starting tick (e.g. to set the starting tick to 100, set the `tick0` to 2) except when `dtick`=*L<f>* (see `dtick` for more info). If the axis `type` is *date*, it should be a date string, like date data. If the axis `type` is *category*, it should be a number, using the scale where each category is assigned a serial number from zero in the order it appears.

Sets the angle of the tick labels with respect to the horizontal. For example, a `tickangle` of -90 draws the tick labels vertically.

Sets the tick label formatting rule using d3 formatting mini-languages which are very similar to those in Python. For numbers, see: https://github.com/d3/d3-format/tree/v1.4.5#d3-format. And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: *%h* for half of the year as a decimal number as well as *%{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*
