When the chart BasicChart#orientation is vertical the base axis is laid out horizontally.
See pvc.options.axes.CartesianAxis to know the additional names by which a cartesian axis can be referred to.
- Borrowed from:
- CartesianChart
This axis can also be accessed by the property name color.
See pvc.options.axes.ColorAxis for more information on the way that the color axes' properties may be accessed.
- Borrowed from:
- Chart
When the chart BasicChart#orientation is vertical the orthogonal axis is laid out vertically.
See pvc.options.axes.CartesianAxis to know the additional names by which a cartesian axis can be referred to.
- Borrowed from:
- CartesianChart
- Deprecated:
- Use pvc.options.axes.CartesianAxis#visible, of the x axis, instead.
- Default Value:
- true
- Borrowed from:

Can be specified to calculate the values of certain dimensions.
- Borrowed from:
- BasicChart
A dimension type group is a group of dimension types that have a common non-numeric prefix in its name.
This property does not define any dimension types, per si, but allows specifying default values for dimension types of a group, that apply in case they are effectively used.
- Borrowed from:
- BasicChart
You don't need to define dimensions unless you want to change their name or properties. Charts automatically define default dimensions to satisfy their visual roles' requirements.
Dimension options can be partial, so that it is possible to override only certain options.
- Borrowed from:
- BasicChart
- Borrowed from:
- BasicChart
For example, if a visual role, has the dimensions "Territory" and "ProductType", a compound value could be shown as "EMEA ~ Classic Cars".
See also #dataSeparator.
- Default Value:
- ' ~ '
- Borrowed from:
- BasicChart
A dimension is considered a measure dimension if there is at least one measure visual role currently bound to it.
- Default Value:
- true
- Borrowed from:
- BasicChart
- Default Value:
- false
- Borrowed from:
- Chart
This option has no effect on other dimensions, even if bound to a "category" visual role. In those cases, explicitly define the dimension with the Date value type.
Dimensions are considered continuous, by default, when they have a continuous value type. However, not all visual roles support continuous dimensions. In those cases, the dimension is treated as a discrete dimension, event though it has a continuous value type.
- Default Value:
- false
- Borrowed from:
- Chart
The syntax of the format string is that of protovis' date formats.
This property changes the default of the pvc.options.DimensionType#rawFormat property, for dimensions with a Date value type.
- Default Value:
- '%Y-%m-%d'
- Borrowed from:
- Chart
- Default Value:
- true
- Borrowed from:
- BasicChart
Relational format
Allows splitting the discrete columns between the "series" and "category" physical groups, in a custom way.By default, if only a single discrete column exists, it is a "category". Otherwise, the first column is a "series" column and all the remaining are "category" columns.
Crosstab format
This is taken to be the number of consecutive discrete columns, from the first, or 1, if there are none.- Borrowed from:
- BasicChart
The capability to use the data source's provided metadata labels is most useful in the relational format, i.e., when #crosstabMode is false. The crosstab format does not provide metadata information for the series/columns data. Also, only when both #isMultiValued and #dataMeasuresInColumns are true, is there label information for the measures metadata.
- Default Value:
- false
- Borrowed from:
- BasicChart
This option only applies when #isMultiValued is true.
When true, the data source contains columns for each combination of "series" columns' values and measure dimension.
When false, the data source contains rows for each combination of "categories" columns' values and measure dimension.
- Borrowed from:
- BasicChart
See also #groupedLabelSep.
- Default Value:
- '~'
- Borrowed from:
- BasicChart
The default value depends on the chart type. The bullet chart type has a default of pvc.options.varia.DataTypeCheckingMode#Extended. All other chart types have a default of pvc.options.varia.DataTypeCheckingMode#Minimum.
Data type checking can be disabled by specifying the value pvc.options.varia.DataTypeCheckingMode#None.
- Borrowed from:
- BasicChart
Relational format
Controls whether the option #measuresIndexes applies.Crosstab format
Depending on the value of #dataMeasuresInColumns, measures are either in columns or in rows.- Default Value:
- false
- Borrowed from:
- BasicChart
This option only applies when #isMultiValued is true.
By default, these are the indexes of continuous columns.
- Borrowed from:
- BasicChart
Can be a string containing a comma separated list of dimension names.
More generally, this option accepts an array of dimensions readers.
- Borrowed from:
- BasicChart
The name of this option is inspired in the crosstab/ matrix format, where the "series" values are placed in the first row, and "category" values are placed in the first column (corner cell is empty).
- Default Value:
- false
- Borrowed from:
- BasicChart
The chart element will be a child of the canvas element.
When unspecified, the chart element will be added as the last child of the HTML document body.
- Borrowed from:

- Borrowed from:
- BasicChart
The value 1 emulates version 1 of CCC.
See also BasicChart#compatFlags.
- Default Value:
- Infinity
- Borrowed from:
- BasicChart
When a chart is rendered explicitly, through its render method, it is possible to control whether the entry animation is performed or not.
This option is only taken into account when #interactive is true.
- Default Value:
- true
- Borrowed from:
- Chart
This option applies even if #selectable is false. This supports scenarios where a custom selection implementation controls what can get selected, but in which clearing selection is decided by the user, in the default way.
This option is only taken into account when #interactive is true.
- Default Value:
- 'emptySpaceClick'
- Borrowed from:
- Chart
If this option is false, any click-related actions will not be executed (ex: #clickAction, Chart#doubleClickAction, or pvc.options.axes.DiscreteCartesianAxis#clickAction).
- Default Value:
- false
- Borrowed from:
- BasicChart
For the selection to be additive, the ctrl key (or cmd in Mac) must be pressed, by the end of the operation.
When false, indicates that any selection made by the user is additive. The ctrl or cmd keys have no effect.
- Default Value:
- true

- Default Value:
- 300
- Borrowed from:

This option is only taken into account when #interactive is true.
- Default Value:
- false
- Borrowed from:

Chart interaction is any of the following kinds of interaction: animation, on-hover highlighting, tooltips, selection, clicking and double-clicking.
When false, all kinds of interaction are disabled. The options controlling specific interaction types are ignored: #animate, #hoverable, pvc.options.Tooltip#enabled, #selectable, Chart#clearSelectionMode and #clickable.
When true all kinds of interaction may be enabled, that being controlled by its own control option.
When printing, with CGG, #interactive is always false, independently of the specified value.
When not printing, the default value of this option is true.

When a value of type boolean is specified, it indicates the visibility of the legend.
- Default Value:
- false
- Borrowed from:
- Chart
It is equivalent to specifying a value of type boolean in #legend, but if both specified this property value takes precedence.
Allows setting the panel's visibility when specifing a value of type pvc.options.panels.LegendPanel in #legend.
- Default Value:
- false
- Borrowed from:

When this property is specified, it sets also the pvc.options.format.FormatProvider#percent format of the chart's format provider, BasicChart#format. Consequently, its value is inherited by the numeric dimension types' pvc.options.DimensionType#format.
Conversely, if the chart's format provider pvc.options.format.FormatProvider#percent format is specified, its value sets this property, Chart#percentValueFormat.
When both are specified, the one in the chart's format provider has precedence.
- Context:
