If *array*, the heatmap's y coordinates are given by *y* (the default behavior when `y` is provided) If *scaled*, the heatmap's y coordinates are given by *y0* and *dy* (the default behavior when `y` is not provided)

Picks a smoothing algorithm use to smooth `z` data.

Determines whether or not gaps (i.e. {nan} or missing values) in the `z` data have hover labels associated with them.

Determines whether or not gaps (i.e. {nan} or missing values) in the `z` data are filled in. It is defaulted to true if `z` is a one dimensional array and `zsmooth` is not false; otherwise it is defaulted to false.

Sets the horizontal gap (in pixels) between bricks.

Sets the vertical gap (in pixels) between bricks.

Sets the hover text formatting rule using d3 formatting mini-languages which are very similar to those in Python. See: https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#d3_format

Determines whether or not the color domain is computed with respect to the input data (here in `z`) or the bounds set in `zmin` and `zmax`  Defaults to `false` when `zmin` and `zmax` are set by the user.

Sets the lower bound of the color domain. Value should have the same units as in `z` and if set, `zmax` must be set as well.

Sets the upper bound of the color domain. Value should have the same units as in `z` and if set, `zmin` must be set as well.

Sets the mid-point of the color domain by scaling `zmin` and/or `zmax` to be equidistant to this point. Value should have the same units as in `z`. Has no effect when `zauto` is `false`.

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`zmin` and `zmax`. Alternatively, `colorscale` may be a palette name string of the following list: Greys,YlGnBu,Greens,YlOrRd,Bluered,RdBu,Reds,Blues,Picnic,Rainbow,Portland,Jet,Hot,Blackbody,Earth,Electric,Viridis,Cividis.
