## R Figure Reference: layout.ternary

• ternary
Parent: layout
Type: named list containing one or more of the keys listed below.
• aaxis
Parent: layout.ternary
Type: named list containing one or more of the keys listed below.
• color
Parent: layout.ternary.aaxis
Type: color
Default: "#444"

Sets default for all colors associated with this axis all at once: line, font, tick, and grid colors. Grid color is lightened by blending this with the plot background Individual pieces can override this.

• dtick
Parent: layout.ternary.aaxis
Type: number or categorical coordinate string

Sets the step in-between ticks on this axis. Use with tick0. Must be a positive number, or special strings available to "log" and "date" axes. If the axis type is "log", then ticks are set every 10^(n"dtick) where n is the tick number. For example, to set a tick mark at 1, 10, 100, 1000, ... set dtick to 1. To set tick marks at 1, 100, 10000, ... set dtick to 2. To set tick marks at 1, 5, 25, 125, 625, 3125, ... set dtick to log_10(5), or 0.69897000433. "log" has several special values; "L<f>", where f is a positive number, gives ticks linearly spaced in value (but not position). For example tick0 = 0.1, dtick = "L0.5" will put ticks at 0.1, 0.6, 1.1, 1.6 etc. To show powers of 10 plus small digits between, use "D1" (all digits) or "D2" (only 2 and 5). tick0 is ignored for "D1" and "D2". If the axis type is "date", then you must convert the time to milliseconds. For example, to set the interval between ticks to one day, set dtick to 86400000.0. "date" also has special values "M<n>" gives ticks spaced by a number of months. n must be a positive integer. To set ticks on the 15th of every third month, set tick0 to "2000-01-15" and dtick to "M3". To set ticks every 4 years, set dtick to "M48"

• exponentformat
Parent: layout.ternary.aaxis
Type: enumerated , one of ( "none" | "e" | "E" | "power" | "SI" | "B" )
Default: "B"

Determines a formatting rule for the tick exponents. For example, consider the number 1,000,000,000. If "none", it appears as 1,000,000,000. If "e", 1e+9. If "E", 1E+9. If "power", 1x10^9 (with 9 in a super script). If "SI", 1G. If "B", 1B.

• gridcolor
Parent: layout.ternary.aaxis
Type: color
Default: "#eee"

Sets the color of the grid lines.

• griddash
Parent: layout.ternary.aaxis
Type: string
Default: "solid"

Sets the dash style of lines. Set to a dash type string ("solid", "dot", "dash", "longdash", "dashdot", or "longdashdot") or a dash length list in px (eg "5px,10px,2px,2px").

• gridwidth
Parent: layout.ternary.aaxis
Type: number greater than or equal to 0
Default: 1

Sets the width (in px) of the grid lines.

• hoverformat
Parent: layout.ternary.aaxis
Type: string
Default: ""

Sets the hover text 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"

• labelalias
Parent: layout.ternary.aaxis
Type: number or categorical coordinate string

Replacement text for specific tick or hover labels. For example using {US: 'USA', CA: 'Canada'} changes US to USA and CA to Canada. The labels we would have shown must match the keys exactly, after adding any tickprefix or ticksuffix. For negative numbers the minus sign symbol used (U+2212) is wider than the regular ascii dash. That means you need to use −1 instead of -1. labelalias can be used with any axis type, and both keys (if needed) and values (if desired) can include html-like tags or MathJax.

• layer
Parent: layout.ternary.aaxis
Type: enumerated , one of ( "above traces" | "below traces" )
Default: "above traces"

Sets the layer on which this axis is displayed. If "above traces", this axis is displayed above all the subplot's traces If "below traces", this axis is displayed below all the subplot's traces, but above the grid lines. Useful when used together with scatter-like traces with cliponaxis set to "FALSE" to show markers and/or text nodes above this axis.

• minexponent
Parent: layout.ternary.aaxis
Type: number greater than or equal to 0
Default: 3

Hide SI prefix for 10^n if |n| is below this number. This only has an effect when tickformat is "SI" or "B".

• showticksuffix
Parent: layout.ternary.aaxis
Type: enumerated , one of ( "all" | "first" | "last" | "none" )
Default: "all"

Same as showtickprefix but for tick suffixes.

• tick0
Parent: layout.ternary.aaxis
Type: number or categorical coordinate string

If the axis type is "log", then you must take the log of your starting tick (e.g. to set the starting tick to 100, set the tick0 to 2) except when dtick="L<f>" (see dtick for more info). If the axis type is "date", it should be a date string, like date data.

• dtick
Parent: layout.ternary.caxis
Type: number or categorical coordinate string

Sets the step in-between ticks on this axis. Use with tick0. Must be a positive number, or special strings available to "log" and "date" axes. If the axis type is "log", then ticks are set every 10^(n"dtick) where n is the tick number. For example, to set a tick mark at 1, 10, 100, 1000, ... set dtick to 1. To set tick marks at 1, 100, 10000, ... set dtick to 2. To set tick marks at 1, 5, 25, 125, 625, 3125, ... set dtick to log_10(5), or 0.69897000433. "log" has several special values; "L<f>", where f is a positive number, gives ticks linearly spaced in value (but not position). For example tick0 = 0.1, dtick = "L0.5" will put ticks at 0.1, 0.6, 1.1, 1.6 etc. To show powers of 10 plus small digits between, use "D1" (all digits) or "D2" (only 2 and 5). tick0 is ignored for "D1" and "D2". If the axis type is "date", then you must convert the time to milliseconds. For example, to set the interval between ticks to one day, set dtick to 86400000.0. "date" also has special values "M<n>" gives ticks spaced by a number of months. n must be a positive integer. To set ticks on the 15th of every third month, set tick0 to "2000-01-15" and dtick to "M3". To set ticks every 4 years, set dtick to "M48"

• exponentformat
Parent: layout.ternary.caxis
Type: enumerated , one of ( "none" | "e" | "E" | "power" | "SI" | "B" )

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"

• labelalias
Parent: layout.ternary.caxis
Type: number or categorical coordinate string

Replacement text for specific tick or hover labels. For example using {US: 'USA', CA: 'Canada'} changes US to USA and CA to Canada. The labels we would have shown must match the keys exactly, after adding any tickprefix or ticksuffix. For negative numbers the minus sign symbol used (U+2212) is wider than the regular ascii dash. That means you need to use −1 instead of -1. labelalias can be used with any axis type, and both keys (if needed) and values (if desired) can include html-like tags or MathJax.

• layer
Parent: layout.ternary.caxis
Type: enumerated , one of ( "above traces" | "below traces" )
Default: "above traces"

• minexponent
Parent: layout.ternary.caxis
Type: number greater than or equal to 0

Type: enumerated , one of ( "all" | "first" | "last" | "none" )
Default: "all"

Same as showtickprefix but for tick suffixes.

• tick0
Parent: layout.ternary.caxis
Type: number or categorical coordinate string

If the axis type is "log", then you must take the log of your starting tick (e.g. to set the starting tick to 100, set the tick0 to 2) except when dtick="L<f>" (see dtick for more info). If the axis type is "date", it should be a date string, like date data.
