Constructor Detail

HLabelEq

public HLabelEq(String s,                int f,                Color c)

Make a label with equation using the LaTeX syntax

Parameters:

s - Text

f - Font size

c - Color

HLabelEq

public HLabelEq(String s,                int f)

Make a equation label (color- black)

Parameters:

s - Text

f - Font size

HLabelEq

public HLabelEq(String s)

Make a label with default attributes

Parameters:

s - text

HLabelEq

public HLabelEq(String s,                double x,                double y)

Make a equation label with specific coordinated in the data system

Parameters:

s - Text

x - Position in X

y - Position in Y

HLabelEq

public HLabelEq(String s,                double x,                double y,                String howToSet)

Make a label with specific coordinates.

Parameters:

s - Text

x - position in X

y - position in Y

howToSet - set it to "NDC" for normalized coordinates (in the range 0-1). This is a data independent position set it to "USER" for the user coordinates

Method Detail

setText

public void setText(String s)

Sets a equation text of the label.

Parameters:

s - new text for the label

getText

public String getText()

Get the equation text of the label.

Returns:

the current text of the label

setColor

public void setColor(Color c)

Sets the color to a specific value

Parameters:

c - color used to draw the label

setColorBackgroud

public void setColorBackgroud(Color c)

Set background color

Parameters:

c -

getColor

public Color getColor()

Get color of the label.

Returns:

the color used to draw the label

getColorBackground

public Color getColorBackground()

Get color of background.

Returns:

the color used to draw the label

setFontSize

public void setFontSize(int f)

Sets the font to a specific value

Parameters:

f - font size used to draw the label

getFontSize

public int getFontSize()

Get the font size of the equation.

Returns:

the font used to draw the label

getImage

public BufferedImage getImage()

Return image of this equation

Returns:

getImageFile

public boolean getImageFile(String fileName)

Return image of this equation as a file. Example of the extension is ".png" or ".jpg".

Returns:

success

toString

public String toString()

Overrides:

toString in class Object

Returns:

a string representation of this label, the text.

setLocation

public void setLocation(double x,                        double y)

Sets the location of the label in data coordinates. Ones set this way, you cannot plot the label, it must first define the location in pixel-coordinates (setLocation(x,y));

Parameters:

x - x-position of the lower-left corner of the text

y - y-position of the lower-left corner of the text

setLocation

public void setLocation(double x,                        double y,                        String howToSet)

Sets the location of the label in data coordinates. Ones set this way, you cannot plot the label, it must first define the location in pixel-coordinates (setLocation(x,y));

Parameters:

x - x-position of the lower-left corner of the text

y - y-position of the lower-left corner of the text

howToSet - set it to "NDC" for normalized coordinates (in the range 0-1). This is a data independent position set it to "USER" for the user coordinates

getPositionCoordinate

public int getPositionCoordinate()

Is the position set?

Returns:

zero if location is not defined of unity if the position is defined in the NDC system 2 if the location is defined in the user coordinates

getX

public double getX()

Returns the X position of the text.

Returns:

the x-position of the text

getY

public double getY()

Returns the Y position of the text.

Returns:

the y-position of the text

doc

public void doc()
