Value of `title` is no longer a simple *string* but a set of sub-attributes. To set the contents of the title, please use `title.text` now.

Former `titlefont` is now the sub-attribute `font` of `title`. To customize title font properties, please use `title.font` now.

HTML font family - the typeface that will be applied by the web browser. The web browser will only be able to apply a font if it is available on the system which it operates. Provide multiple font families, separated by commas, to indicate the preference in which to apply fonts if they aren't available on the system. The Chart Studio Cloud (at https://chart-studio.plotly.com or on-premise) generates images on a server, where only a select number of fonts are installed and supported. These include *Arial*, *Balto*, *Courier New*, *Droid Sans*,, *Droid Serif*, *Droid Sans Mono*, *Gravitas One*, *Old Standard TT*, *Open Sans*, *Overpass*, *PT Sans Narrow*, *Raleway*, *Times New Roman*.

Sets the horizontal alignment of the `text` within the box. Has an effect only if `text` spans two or more lines (i.e. `text` contains one or more <br> HTML tags) or if an explicit width is set to override the text width.

Sets the end annotation arrow head style.

Sets the annotation arrow head position.

Sets the size of the end annotation arrow head, relative to `arrowwidth`. A value of 1 (default) gives a head about 3x as wide as the line.

Sets the width (in px) of annotation arrow line.

Sets the x component of the arrow tail about the arrow head. If `axref` is `pixel`, a positive (negative) component corresponds to an arrow pointing from right to left (left to right). If `axref` is not `pixel` and is exactly the same as `xref`, this is an absolute value on that axis, like `x`, specified in the same coordinates as `xref`.
