Method Detail

getValue

public java.lang.String getValue()

This function returns the value of the string. Combine all elements in string array and separate them with a newline character.

Returns:

The value of the string as a String object.

setValue

public void setValue(java.lang.String value)

This function sets the value of the string. Break up the string when a newline character is found. Then store the substrings in a string array.

Parameters:

value - The string value to set.

getValues

public java.lang.String[] getValues()

This function returns the value of the string array.

Returns:

The value of the string as a String array

setValues

public void setValues(java.lang.String[] value)

This function sets the value of the string array.

Parameters:

value - The string array value to set.

setVisible

public void setVisible(boolean visible)

This function sets the object to either visible or invisible.

Parameters:

visible - The state of the object

isVisible

public boolean isVisible()

This function returns whether both this object and the referenced object are visible

Returns:

visible or not

getReferenceObject

public IReferenceObj getReferenceObject()

This function returns the referenced object of this annotation.

Returns:

the referenced object

IDataLine

setReferenceObject

public void setReferenceObject(IReferenceObj refObj)

This function sets the referenced object of this annotation.

Parameters:

refObj - The referenced object

IDataLine

getRelativePosition

public Point_2D getRelativePosition()

This function gets the relative position to the referenced object. The return value is the ratio of position different between the referenced position and the annotation position to the canvas size. If the return value is (ratioX1, ratioY1), the referenced position is (ratioX2, ratioY2) and the canvas size is (width, height), the annotation will be draw at position ( width*(ratioX1 + ratioX2), height*(ratioY1 + ratioY2) ) Note that position (0, 0) represents the lower-left corner of the chart canvas.

Returns:

The relative position

setRelativePosition

public void setRelativePosition(Point_2D relativePos)

This function sets the relative position to the referenced object.

Parameters:

relativePos - The relative position
