Sets this color bar's title font. Note that the title's font used to be set by the now deprecated `titlefont` attribute.

Determines the location of color bar's title with respect to the color bar. Defaults to *top* when `orientation` if *v* and  defaults to *right* when `orientation` if *h*. Note that the title's location used to be set by the now deprecated `titleside` attribute.

Sets the title of the color bar. Note that before the existence of `title.text`, the title's contents used to be defined as the `title` attribute itself. This behavior has been deprecated.

Sets the x position of the color bar (in plot fraction). Defaults to 1.02 when `orientation` is *v* and 0.5 when `orientation` is *h*.

Sets this color bar's horizontal position anchor. This anchor binds the `x` position to the *left*, *center* or *right* of the color bar. Defaults to *left* when `orientation` is *v* and *center* when `orientation` is *h*.

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

Sets the y position of the color bar (in plot fraction). Defaults to 0.5 when `orientation` is *v* and 1.02 when `orientation` is *h*.

Sets this color bar's vertical position anchor This anchor binds the `y` position to the *top*, *middle* or *bottom* of the color bar. Defaults to *middle* when `orientation` is *v* and *bottom* when `orientation` is *h*.

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

Sets the colorscale. The colorscale must be an array containing arrays mapping a normalized value to an rgb, rgba, hex, hsl, hsv, or named color string. At minimum, a mapping for the lowest (0) and highest (1) values are required. For example, `[[0, 'rgb(0,0,255)'], [1, 'rgb(255,0,0)']]`. To control the bounds of the colorscale in color space, use`cmin` and `cmax`. Alternatively, `colorscale` may be a palette name string of the following list: Blackbody,Bluered,Blues,Cividis,Earth,Electric,Greens,Greys,Hot,Jet,Picnic,Portland,Rainbow,RdBu,Reds,Viridis,YlGnBu,YlOrRd.

Reverses the color mapping if true. If true, `cmin` will correspond to the last color in the array and `cmax` will correspond to the first color.
