Sets the shapes's sizing mode along the x axis. If set to *scaled*, `x0`, `x1` and x coordinates within `path` refer to data values on the x axis or a fraction of the plot area's width (`xref` set to *paper*). If set to *pixel*, `xanchor` specifies the x position in terms of data or plot fraction but `x0`, `x1` and x coordinates within `path` are pixels relative to `xanchor`. This way, the shape can have a fixed width while maintaining a position relative to data or plot fraction.

Only relevant in conjunction with `xsizemode` set to *pixel*. Specifies the anchor point on the x axis to which `x0`, `x1` and x coordinates within `path` are relative to. E.g. useful to attach a pixel sized shape to a certain data value. No effect when `xsizemode` not set to *pixel*.

Sets the shape's starting x position. See `type` and `xsizemode` for more info.

Sets the shape's end x position. See `type` and `xsizemode` for more info.

Sets the shapes's sizing mode along the y axis. If set to *scaled*, `y0`, `y1` and y coordinates within `path` refer to data values on the y axis or a fraction of the plot area's height (`yref` set to *paper*). If set to *pixel*, `yanchor` specifies the y position in terms of data or plot fraction but `y0`, `y1` and y coordinates within `path` are pixels relative to `yanchor`. This way, the shape can have a fixed height while maintaining a position relative to data or plot fraction.

Only relevant in conjunction with `ysizemode` set to *pixel*. Specifies the anchor point on the y axis to which `y0`, `y1` and y coordinates within `path` are relative to. E.g. useful to attach a pixel sized shape to a certain data value. No effect when `ysizemode` not set to *pixel*.

Sets the shape's starting y position. See `type` and `ysizemode` for more info.

Sets the shape's end y position. See `type` and `ysizemode` for more info.

For `type` *path* - a valid SVG path with the pixel values replaced by data values in `xsizemode`/`ysizemode` being *scaled* and taken unmodified as pixels relative to `xanchor` and `yanchor` in case of *pixel* size mode. There are a few restrictions / quirks only absolute instructions, not relative. So the allowed segments are: M, L, H, V, Q, C, T, S, and Z arcs (A) are not allowed because radius rx and ry are relative. In the future we could consider supporting relative commands, but we would have to decide on how to handle date and log axes. Note that even as is, Q and C Bezier paths that are smooth on linear axes may not be smooth on log, and vice versa. no chained "polybezier" commands - specify the segment type for each one. On category axes, values are numbers scaled to the serial numbers of categories because using the categories themselves there would be no way to describe fractional positions On data axes: because space and T are both normal components of path strings, we can't use either to separate date from time parts. Therefore we'll use underscore for this purpose: 2015-02-21_13:45:56.789
