This option is only supported for a
continuous axis. |
hAxis.minValue | number | automatic | hAxis property that specifies the lowest horizontal axis grid line. The actual grid line will be the lower of two values: the minValue option value, or the lowest data value, rounded down to the next lower grid mark.
This option is only supported for a
continuous axis. |

|
legend.alignment | string | automatic | Alignment of the legend. Can be one of the following:
Start, center, and end are relative to the style -- vertical or horizontal -- of the legend. For example, in a 'right' legend, 'start' and 'end' are at the top and bottom, respectively; for a 'top' legend, 'start' and 'end' would be at the left and right of the area, respectively.
The default value depends on the legend's position. For 'bottom' legends, the default is 'center'; other legends default to 'start'.
|
legend.textStyle | Object | {color: 'black', fontName: <global-font-name>, fontSize: <global-font-size>} |
An object that specifies the legend text style. The object has this format:
{color: <string>, fontName: <string>, fontSize: <number>}
The
color can be any HTML color string, for example: 'red' or '#00cc00' . Also see fontName and fontSize . |

series | Array of objects, or object with nested objects | {} |
An array of objects, each describing the format of the corresponding series in the chart. To use default values for a series, specify an empty object {}. If a series or a value is not specified, the global value will be used. Each object supports the following properties:
You can specify either an array of objects, each of which applies to the series in the order given, or you can specify an object where each child has a numeric key indicating which series it applies to. For example, the following two declarations are identical, and declare the first series as black and absent from the legend, and the fourth as red and absent from the legend:
series: [{color: 'black', visibleInLegend: false},{}, {}, {color: 'red', visibleInLegend: false}] series: {0:{color: 'black', visibleInLegend: false}, 3:{color: 'red', visibleInLegend: false}} |

vAxes | Array of object, or object with child objects | null |
Specifies properties for individual vertical axes, if the chart has multiple vertical axes. Each child object is a
vAxis object, and can contain all the properties supported by vAxis . These property values override any global settings for the same property.
To specify a chart with multiple vertical axes, first define a new axis using
series.targetAxisIndex , then configure the axis usingvAxes . The following example assigns series 2 to the right axis and specifies a custom title and text style for it: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
vAxis object shown above:vAxes:[ {}, // Nothing specified for axis 0 {title:'Losses',textStyle:{color: 'red'}} // Axis 1 ] |
vAxis | Object | null |
