Reverses the color mapping if true. Has an effect only if in `marker.color`is set to a numerical array. If true, `marker.cmin` will correspond to the last color in the array and `marker.cmax` will correspond to the first color.

Determines whether or not a colorbar is displayed for this trace. Has an effect only if in `marker.color`is set to a numerical array.

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

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

Sets the length of the color bar This measure excludes the padding of both ends. That is, the color bar length is this length minus the padding on both ends.

Sets the x position of the color bar (in plot fraction).

Sets this color bar's horizontal position anchor. This anchor binds the `x` position to the *left*, *center* or *right* of the color bar.

Sets the amount of padding (in px) along the x direction.

Sets the y position of the color bar (in plot fraction).

Sets this color bar's vertical position anchor This anchor binds the `y` position to the *top*, *middle* or *bottom* of the color bar.

Sets the amount of padding (in px) along the y direction.

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

Sets the width (in px) or the border enclosing this color bar.

Sets the tick mode for this axis. If *auto*, the number of ticks is set via `nticks`. If *linear*, the placement of the ticks is determined by a starting position `tick0` and a tick step `dtick` (*linear* is the default value if `tick0` and `dtick` are provided). If *array*, the placement of the ticks is set via `tickvals` and the tick text is `ticktext`. (*array* is the default value if `tickvals` is provided).

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*.
