Overview
A chart that lets you render each series as a different marker type from the following list: line, area, bars, candlesticks, and stepped area.
To assign a default marker type for series, specify the seriesType property.
Use the series property to specify properties of each series individually.

Configuration Options
| Name | |
|---|---|
| aggregationTarget |
How multiple data selections are rolled up into tooltips:
aggregationTarget will often be used in tandem with selectionMode
and tooltip.trigger, e.g.:

|
| animation.startup |
Determines if the chart will animate on the initial draw. If Type: boolean
Default false
|
| annotations.boxStyle |
For charts that support
annotations,
the var options = { annotations: { boxStyle: { // Color of the box outline. stroke: '#888', // Thickness of the box outline. strokeWidth: 1, // x-radius of the corner curvature. rx: 10, // y-radius of the corner curvature. ry: 10, // Attributes for linear gradient fill. gradient: { // Start color for gradient. color1: '#fbf6a7', // Finish color for gradient. color2: '#33b679', // Where on the boundary to start and // end the color1/color2 gradient, // relative to the upper left corner // of the boundary. x1: '0%', y1: '0%', x2: '100%', y2: '100%', // If true, the boundary for x1, // y1, x2, and y2 is the box. If // false, it's the entire chart. useObjectBoundingBoxUnits: true } } } }; This option is currently supported for area, bar, column, combo, line, and scatter charts. It is not supported by the Annotation Chart. Type: object
Default: null
|
| annotations.datum |
For charts that support
annotations,
the
annotations.datum object lets you override
Google Charts' choice for annotations provided for individual
data elements (such as values displayed with each bar on a bar
chart). You can control the color
with annotations.datum.stem.color, the stem length
with annotations.datum.stem.length, and the style with annotations.datum.style.
Type: object
Default: color is "black"; length is 12; style is "point".
|
| annotations.domain |
For charts that support
annotations,
the
annotations.domain object lets you override
Google Charts' choice for annotations provided for a domain (the
major axis of the chart, such as the X axis on a typical line
chart). You can control the color
with annotations.domain.stem.color, the stem length
with annotations.domain.stem.length, and the style with annotations.domain.style.
Type: object
Default: color is "black"; length is 5; style is "point".
|
| annotations.highContrast |
For charts that support
annotations,
the
annotations.highContrast boolean lets you override Google Charts' choice of
the annotation color. By default, annotations.highContrast is true, which causes
Charts to select an annotation color with good contrast: light colors on dark backgrounds, and
dark on light. If you set annotations.highContrast to false and don't specify
your own annotation color, Google Charts will use the default series color for the annotation:
Type: boolean
Default: true
|
| annotations.stem |
For charts that support
annotations,
the
annotations.stem object lets you override
Google Charts' choice for the stem style. You can control color
with annotations.stem.color and the stem length

length option has no effect on annotations with
style 'line': for 'line' datum
annotations, the stem length is always the same as the text, and
for 'line' domain annotations, the stem extends
across the entire chart.
Type: object

If true, show colored squares next to the series information in the tooltip. The default is
true when Type: boolean
Default: automatic
|
| tooltip.textStyle |
An object that specifies the tooltip text style. The object has this format:
{ color: <string>,
fontName: <string>,
fontSize: <number>,
bold: <boolean>,
italic: <boolean> }
The Type: object
Default:
{color: 'black', fontName: <global-font-name>, fontSize: <global-font-size>}
|
| tooltip.trigger |
The user interaction that causes the tooltip to be displayed:
Type: string
Default: 'focus'
|
| vAxes |
Specifies properties for individual vertical axes, if the chart has multiple vertical axes.
Each child object is a
To specify a chart with multiple vertical axes, first define a new axis using
{
series: {
2: {
targetAxisIndex:1
}
},
vAxes: {
1: {
title:'Losses',
textStyle: {color: 'red'}
}
}
}
This property can be either an object or an array: the object is a collection of objects,
each with a numeric label that specifies the axis that it defines--this is the format shown
above; the array is an array of objects, one per axis. For example, the following array-style
notation is identical to the
vAxes: [
{}, // Nothing specified for axis 0
{
title:'Losses',
textStyle: {color: 'red'} // Axis 1
}
]
Type: Array of object, or object with child objects
Default: null
|
| vAxis |
An object with members to configure various vertical axis elements. To specify properties of this object, you can use object literal notation, as shown here: {title: 'Hello', titleTextStyle: {color: '#FF0000'}}Type: object
Default: null
|
| vAxis.baseline |
Type: number
Default: automatic
|
| vAxis.baselineColor |
Specifies the color of the baseline for the vertical axis. Can be any HTML color string, for
example: Type: number
Default: 'black'
|
| vAxis.direction |
The direction in which the values along the vertical axis grow. By default, low values
are on the bottom of the chart. Specify Type: 1 or -1
Default: 1
|
| vAxis.format |
A format string for numeric axis labels. This is a subset of the
ICU pattern set
.
For instance,
The actual formatting applied to the label is derived from the locale the API has been loaded with. For more details, see loading charts with a specific locale .
In computing tick values and gridlines, several alternative
combinations of all the relevant gridline
options will be considered and alternatives will be rejected if the
formatted tick labels would be duplicated or overlap.
So you can specify Type: string
Default: auto
|
| vAxis.gridlines |
An object with members to configure the gridlines on the vertical axis. Note that vertical axis gridlines are drawn horizontally. To specify properties of this object, you can use object literal notation, as shown here: {color: '#333', minSpacing: 20}Type: object
Default: null
|
| vAxis.gridlines.color |
The color of the vertical gridlines inside the chart area. Specify a valid HTML color string. Type: string
Default: '#CCC'
|
| vAxis.gridlines.count |

If you specify a positive number for Type: number
Default: -1
|
| vAxis.gridlines.interval |

but it is analogous to the
Type: number between 1 and 10, not including 10.
Default: computed
|
| vAxis.gridlines.minSpacing |
The minimum screen space, in pixels, between hAxis major gridlines.
The default for major gridlines is Type: number
Default: computed
|
| vAxis.gridlines.multiple |
All gridline and tick values must be a multiple of this
option's value. Note that, unlike for intervals, powers of 10
times the multiple are not considered.
So you can force ticks to be integers by specifying
Type: number
Default: 1
|
| vAxis.gridlines.units |
Overrides the default format for various aspects of date/datetime/timeofday data types when used with chart computed gridlines. Allows formatting for years, months, days, hours, minutes, seconds, and milliseconds. General format is:
gridlines: {
units: {
years: {format: [/*format strings here*/]},
months: {format: [/*format strings here*/]},
days: {format: [/*format strings here*/]},
hours: {format: [/*format strings here*/]},
minutes: {format: [/*format strings here*/]},
seconds: {format: [/*format strings here*/]},

Default: null
|
| vAxis.minorGridlines.color |
The color of the vertical minor gridlines inside the chart area. Specify a valid HTML color string. Type: string

|
| vAxis.minorGridlines.count |
The minorGridlines.count option is mostly deprecated, except for disabling minor gridlines by setting the count to 0. The number of minor gridlines depends on the interval between major gridlines (see vAxis.gridlines.interval) and the minimum required space (see vAxis.minorGridlines.minSpacing). Type: number
Default: 1
|
| vAxis.minorGridlines.interval |
The minorGridlines.interval option is like the major gridlines
interval option, but the interval that is chosen will always
be an even divisor of the major gridline interval.
The default interval for linear scales is
Type: number
Default:1
|
| vAxis.minorGridlines.minSpacing |
The minimum required space, in pixels, between adjacent minor gridlines, and between minor and major gridlines. The default value is 1/2 the minSpacing of major gridlines for linear scales, and 1/5 the minSpacing for log scales. Type: number
Default:computed
|
| vAxis.minorGridlines.multiple |
Same as for major Type: number
Default: 1
|
| vAxis.minorGridlines.units |
Overrides the default format for various aspects of date/datetime/timeofday data types when used with chart computed minorGridlines. Allows formatting for years, months, days, hours, minutes, seconds, and milliseconds. General format is:
