Method Detail

getAutoWrap

public java.lang.Boolean getAutoWrap()

Returns:

true if axis labels (only when it is horizontal) are wrapped

setAutoWrap

@StudioProperty(defaultValue="false")
public CategoryAxis setAutoWrap(java.lang.Boolean autoWrap)

Set autoWrap to true if axis labels (only when it is horizontal) should be wrapped if they don't fit in the allocated space. If axis is vertical, you should set axis.ignoreAxisWidth to true in order this feature to work. If not set the default value is false.

Parameters:

autoWrap - autoWrap option

Returns:

category axis

getEqualSpacing

public java.lang.Boolean getEqualSpacing()

Returns:

true if data points is placed at equal intervals

setEqualSpacing

@StudioProperty(defaultValue="false")
public CategoryAxis setEqualSpacing(java.lang.Boolean equalSpacing)

Set equalSpacing to true if want dates to be parsed (displayed on the axis, balloons, etc), but data points to be placed at equal intervals (omitting dates with no data). In case your category axis values are Date objects and parseDates is set to true. If not set the default value is false.

Parameters:

equalSpacing - equalSpacing option

Returns:

category axis

getForceShowField

public java.lang.String getForceShowField()

Returns:

force show field name

setForceShowField

@StudioProperty
public CategoryAxis setForceShowField(java.lang.String forceShowField)

Sets force show field name from data provider which specifies if the category value should always be shown. For example: forceShowField = "forceShow" and data contains true or false. Note, this works only when parseDates is set to false.

Parameters:

forceShowField - force show field string

Returns:

category axis

getGridPosition

public GridPosition getGridPosition()

Returns:

grid position

setGridPosition

@StudioProperty(type=ENUMERATION,
                defaultValue="MIDDLE")
public CategoryAxis setGridPosition(GridPosition gridPosition)

Sets grid position: grid line is placed on the center of a cell or on the beginning of a cell. Possible values are: "start" and "middle" This setting doesn't work if parseDates is set to true. If not set the default value is MIDDLE.

Parameters:

gridPosition - grid position

Returns:

category axis

getMinPeriod

public DatePeriod getMinPeriod()

Returns:

the shortest period of your data

setMinPeriod

@StudioProperty(type=ENUMERATION,
                defaultValue="DAYS")
public CategoryAxis setMinPeriod(DatePeriod minPeriod)

Sets the shortest period of your data. This should be set only if parseDates is set to true. If not set the default value is "DD".

Parameters:

minPeriod - the shortest period of your data

Returns:

category axis

getParseDates

public java.lang.Boolean getParseDates()

Returns:

true if parseDates is enabled

setParseDates

@StudioProperty(defaultValue="false")
public CategoryAxis setParseDates(java.lang.Boolean parseDates)

Set parseDates to true if your category axis values are date-based. In this case the chart will parse dates and will place your data points at irregular intervals. If you want dates to be parsed, but data points to be placed at equal intervals, set both parseDates and equalSpacing to true.

Note, if you are specifying dates as strings in your data, i.e. "2015-01-05", we strongly recommend setting dataDateFormat as well.

Important, if parseDates is set to true, the data points need to come pre-ordered in ascending order. Data with incorrect order might result in visual and functional glitches on the chart.

If not set the default value is false.

Parameters:

parseDates - parseDates option

Returns:

category axis

getStartOnAxis

public java.lang.Boolean getStartOnAxis()

Returns:

true if the graph starts on axis

setStartOnAxis

@StudioProperty
public CategoryAxis setStartOnAxis(java.lang.Boolean startOnAxis)

Set startOnAxis to true if the graph should start on axis. In case you display columns, it is recommended to set startOnAxis to false. If parseDates is set to true, startOnAxis will always be false, unless equalSpacing is set to true.

Parameters:

startOnAxis - startOnAxis option

Returns:

category axis

getCategoryFunction

public JsFunction getCategoryFunction()

Returns:

JS function that is used as categoryValue for current item

setCategoryFunction

public CategoryAxis setCategoryFunction(JsFunction categoryFunction)

Sets JS function that returns the value that should be used as categoryValue for current item. If categoryFunction is set, the return value of the custom data function takes precedence over categoryField. When a chart calls this method, it passes category value, data item from chart's data provider and reference to categoryAxis: categoryFunction(category, dataItem, categoryAxis); This method can be used both when category axis parses dates and when it doesn't. If axis parses dates, your categoryFunction should return Date object.

Parameters:

categoryFunction - JS function

Returns:

category axis

getLabelColorField

public java.lang.String getLabelColorField()

Returns:

label color field

setLabelColorField

@StudioProperty(type=PROPERTY_PATH_REF)
public CategoryAxis setLabelColorField(java.lang.String labelColorField)

Sets label color field. Works only with non-date-based data.

Parameters:

labelColorField - label color field string

Returns:

category axis

getTickPosition

public java.lang.String getTickPosition()

Returns:

position of an axis tick

setTickPosition

@StudioProperty(type=OPTIONS,
                options={"middle","start"},
                defaultValue="middle")
public CategoryAxis setTickPosition(java.lang.String tickPosition)

Sets position of an axis tick. Available settings: "middle", "start". Works only with non-date-based data. If not set the default value is false. If not set the default value is "middle".

Parameters:

tickPosition - tick position string

Returns:

category axis

getTwoLineMode

public java.lang.Boolean getTwoLineMode()

Returns:

true category axis displays date strings of bot small and big period, in two rows

setTwoLineMode

@StudioProperty(defaultValue="false")
public void setTwoLineMode(java.lang.Boolean twoLineMode)

Set twoLineMode to true, category axis will display date strings of bot small and big period, in two rows, at the position where bigger period changes. Works only when parseDates is set to true and equalSpacing is false. If not set the default value is false.

Parameters:

twoLineMode - twoLineMode option

getLabelFunction

public JsFunction getLabelFunction()

Returns:

JS function to format category axis labels

setLabelFunction

public CategoryAxis setLabelFunction(JsFunction labelFunction)

Sets JS function to format category axis labels. If this function is set, then it is called with the following parameters passed: if dates are not parsed - labelFunction(valueText, serialDataItem, categoryAxis), if dates are parsed - labelFunction(valueText, date, categoryAxis). Js function should return string which will be displayed on the axis.

Parameters:

labelFunction - Js function

Returns:

category axis

getWidthField

public java.lang.String getWidthField()

Returns:

width field name

setWidthField

@StudioProperty(type=PROPERTY_PATH_REF)

getClassNameField

public java.lang.String getClassNameField()

Returns:

class name field

setClassNameField

@StudioProperty(type=PROPERTY_PATH_REF)
public CategoryAxis setClassNameField(java.lang.String classNameField)

Sets CSS class name field. If classNameField is set and AbstractChart.addClassNames is enabled, the category axis labels, ticks and grid will have this class name set. Note, this will not work if the axis is date-based.

Parameters:

classNameField - class name field string

Returns:

category axis
