Sets the text elements associated with the cones. If trace `hoverinfo` contains a *text* flag and *hovertext* is not set, these elements will be seen in the hover labels.

Sets the x components of the vector field.

Sets the hover text formatting rulefor `u`  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.By default the values are formatted using generic number format.

Sets the source reference on Chart Studio Cloud for `u`.

Sets the y components of the vector field.

Sets the hover text formatting rulefor `v`  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.By default the values are formatted using generic number format.

Sets the source reference on Chart Studio Cloud for `v`.

Sets the z components of the vector field.

Sets the hover text formatting rulefor `w`  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.By default the values are formatted using generic number format.

Sets the source reference on Chart Studio Cloud for `w`.

Sets the x coordinates of the vector field and of the displayed cones.

Sets the y coordinates of the vector field and of the displayed cones.

Sets the z coordinates of the vector field and of the displayed cones.

Sets the hover text formatting rulefor `z`  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*By default the values are formatted using `zaxis.hoverformat`.
