Method Detail

getDesiredTickCount

public int getDesiredTickCount()

Gets the number of the ticks available on the axis. If a value less than 2 is set, the property is reset to its default value.

Returns:

The number of the ticks available on the axis. If a value less than 2 is set, the property is reset to its default value.

setDesiredTickCount

public void setDesiredTickCount(int value)

Sets the number of the ticks available on the axis. If a value less than 2 is set, the property is reset to its default value.

Parameters:

value - The number of the ticks available on the axis. If a value less than 2 is set, the property is reset to its default value.

getRangeExtendDirection

public int getRangeExtendDirection()

Gets a value that specifies how the auto-range of this axis will be extended so that each data point is visualized in the best possible way.

Returns:

A value that specifies how the auto-range of this axis will be extended so that each data point is visualized in the best possible way.

setRangeExtendDirection

public void setRangeExtendDirection(int value)

Sets a value that specifies how the auto-range of this axis will be extended so that each data point is visualized in the best possible way.

Parameters:

value - A value that specifies how the auto-range of this axis will be extended so that each data point is visualized in the best possible way.

getMajorStep

public double getMajorStep()

Gets the user-defined major step of the axis.

Returns:

The user-defined major step of the axis.

setMajorStep

public void setMajorStep(double value)

Sets a custom major step of the axis. If the major step is set to 0.0, the value is reset and the steps are generated automatically.

Parameters:

value - The user-defined major step of the axis

getMinimum

public double getMinimum()

Gets the user-defined minimum of the axis.

Returns:

The user-defined minimum of the axis.

setMinimum

public void setMinimum(double value)

Sets the user-defined minimum of the axis.

Parameters:

value - The user-defined minimum of the axis.

getMaximum

public double getMaximum()

Gets the user-defined maximum of the axis.

Returns:

The user-defined maximum of the axis.

setMaximum

public void setMaximum(double value)

Sets the user-defined maximum of the axis.

Parameters:

value - The user-defined maximum of the axis.

getActualRange

public ValueRange<Double> getActualRange()

Gets the actual range (minimum and maximum values) used by the axis.

Returns:

The actual range (minimum and maximum values) used by the axis.

onZoomChanged

public void onZoomChanged()

Description copied from class: AxisModel

Called when the zoom factor of the owning chart changes.

Overrides:
