Volume
Overview
The volume
trace type is used to create 3D volume plots, which visualize 3D volumetric data. Volume plots are useful for representing datasets where the values at each (x, y, z) point in a grid represent a density or scalar field, such as medical imaging, fluid dynamics, and other scientific data.
You can customize the opacity, surface levels, and colors to effectively visualize the internal structure of the volume.
Common Uses
- Medical Imaging: Visualizing 3D scans such as MRI or CT data.
- Fluid Dynamics: Representing 3D fields of density or pressure.
- Scientific Visualization: Displaying any 3D scalar field or volumetric data.

Attributes
These attributes apply to traces where trace.props.type
is set to volume
. You would configure these attributes on the trace with the trace.props
object.

- HTML font family - the typeface that will be applied by the web browser. The web browser can only apply a font if it is available on the system where it runs. Provide multiple font families, separated by commas, to indicate the order in which to apply fonts if they aren't available.
- Sets the shape and color of the shadow behind text. auto places minimal shadow and applies contrast text font color. See https://developer.mozilla.org/en-US/docs/Web/CSS/text-shadow for additional options.
- Sets the tick label formatting rule 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

. - Template string used for rendering the information that appear on hover box. Note that this will override
hoverinfo
. Variables are inserted using %{variable}, for example "y: %{y}" as well as %{xother}, {%xother}, {%_xother}, {%xother_}. When showing info for several points, xother will be added to those with different x positions from the first point. An underscore before or after (x|y)other will add a space on that side, only when this field is shown. Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax. The variables available inhovertemplate
are the ones emitted as event data described at this link https://plotly.com/javascript/plotlyjs-events/#event-data. Additionally, every attributes that can be specified per-point (the ones that arearrayOk: true
) are available. Anything contained in tag<extra>
is displayed in the secondary box, for example "{fullData.name} ". To hide the secondary box completely, use an empty tag<extra></extra>
