Sets the marker symbol type. Adding 100 is equivalent to appending *-open* to a symbol name. Adding 200 is equivalent to appending *-dot* to a symbol name. Adding 300 is equivalent to appending *-open-dot* or *dot-open* to a symbol name.

Sets a maximum number of points to be drawn on the graph. *0* corresponds to no limit.

Has an effect only if `marker.size` is set to a numerical array. Sets the scale factor used to determine the rendered size of marker points. Use with `sizemin` and `sizemode`.

Has an effect only if `marker.size` is set to a numerical array. Sets the minimum size (in px) of the rendered marker points.

Has an effect only if `marker.size` is set to a numerical array. Sets the rule for which the data in `size` is converted to pixels.

Sets the width (in px) of the lines bounding the marker points.

Sets themarker.linecolor. It accepts either a specific color or an array of numbers that are mapped to the colorscale relative to the max and min values of the array or relative to `marker.line.cmin` and `marker.line.cmax` if set.

Determines whether or not the color domain is computed with respect to the input data (here in `marker.line.color`) or the bounds set in `marker.line.cmin` and `marker.line.cmax`  Has an effect only if in `marker.line.color`is set to a numerical array. Defaults to `false` when `marker.line.cmin` and `marker.line.cmax` are set by the user.

Sets the lower bound of the color domain. Has an effect only if in `marker.line.color`is set to a numerical array. Value should have the same units as in `marker.line.color` and if set, `marker.line.cmax` must be set as well.

Sets the upper bound of the color domain. Has an effect only if in `marker.line.color`is set to a numerical array. Value should have the same units as in `marker.line.color` and if set, `marker.line.cmin` must be set as well.

Sets the mid-point of the color domain by scaling `marker.line.cmin` and/or `marker.line.cmax` to be equidistant to this point. Has an effect only if in `marker.line.color`is set to a numerical array. Value should have the same units as in `marker.line.color`. Has no effect when `marker.line.cauto` is `false`.
