Canvas function reference

Behind the scenes, Canvas is driven by a powerful expression language, with dozens of functions and other capabilities, including table transforms, type casting, and sub-expressions.

The Canvas expression language also supports TinyMath functions, which perform complex math calculations.

A * denotes a required argument.

A † denotes an argument can be passed multiple times.

A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z

A

all

Returns true if all of the conditions are met. See also any.

Expression syntax

  1. all {neq "foo"} {neq "bar"} {neq "fizz"}
  2. all condition={gt 10} condition={lt 20}

Code example

  1. filters
  2. | demodata
  3. | math "mean(percent_uptime)"
  4. | formatnumber "0.0%"
  5. | metric "Average uptime"
  6.   metricFont={
  7.     font size=48 family="'Open Sans', Helvetica, Arial, sans-serif"
  8.       color={
  9.         if {all {gte 0} {lt 0.8}} then="red" else="green"
  10.       }
  11.       align="center" lHeight=48
  12.   }
  13. | render

This sets the color of the metric text to "red" if the context passed into metric is greater than or equal to 0 and less than 0.8. Otherwise, the color is set to "green".

Accepts: null

ArgumentTypeDescription

Unnamed * †

Alias: condition

boolean

The conditions to check.

Returns: boolean

alterColumn

Converts between core types, including string, number, null, boolean, and date, and renames columns. See also mapColumn and staticColumn.

Expression syntax

  1. alterColumn "cost" type="string"
  2. alterColumn column="@timestamp" name="foo"

Code example

  1. filters
  2. | demodata
  3. | alterColumn "time" name="time_in_ms" type="number"
  4. | table
  5. | render

This renames the time column to time_in_ms and converts the type of the column’s values from date to number.

Accepts: datatable

ArgumentTypeDescription

Unnamed *

Alias: column

string

The name of the column to alter.

name

string

The resultant column name. Leave blank to not rename.

type

string

The type to convert the column to. Leave blank to not change the type.

Returns: datatable

any

Returns true if at least one of the conditions is met. See also all.

Expression syntax

  1. any {eq "foo"} {eq "bar"} {eq "fizz"}
  2. any condition={lte 10} condition={gt 30}

Code example

  1. filters
  2. | demodata
  3. | filterrows {
  4.     getCell "project" | any {eq "elasticsearch"} {eq "kibana"} {eq "x-pack"}
  5.   }
  6. | pointseries color="project" size="max(price)"
  7. | pie
  8. | render

This filters out any rows that don’t contain "elasticsearch", "kibana" or "x-pack" in the project field.

Accepts: null

ArgumentTypeDescription

Unnamed * †

Alias: condition

boolean

The conditions to check.

Returns: boolean

as

Creates a datatable with a single value. See also getCell.

Expression syntax

  1. as
  2. as "foo"
  3. as name="bar"

Code example

  1. filters
  2. | demodata
  3. | ply by="project" fn={math "count(username)" | as "num_users"} fn={math "mean(price)" | as "price"}
  4. | pointseries x="project" y="num_users" size="price" color="project"
  5. | plot
  6. | render

as casts any primitive value (string, number, date, null) into a datatable with a single row and a single column with the given name (or defaults to "value" if no name is provided). This is useful when piping a primitive value into a function that only takes datatable as an input.

In the example, ply expects each fn subexpression to return a datatable in order to merge the results of each fn back into a datatable, but using a math aggregation in the subexpressions returns a single math value, which is then cast into a datatable using as.

Accepts: string, boolean, number, null
