Class HLabel

  • All Implemented Interfaces:
    Serializable


    public class HLabelextends Objectimplements Serializable
    Create an interactive Label in the USER or NDC coordinates. The label can be defined in the NDC (normalized coordinate system) or the user coordinate. Only one line of the text can be shown. To show several lines of the text, use

    • Constructor Detail

      • HLabel

        public HLabel(String s,      Font f,      Color c)
        Make a text label at (0,0) in the data coordinates (USER). The position is depends of the user coordinated, so consider NDC.
        Parameters:
        s - Text
        f - Font
        c - Color
      • HLabel

        public HLabel(String s,      Font f)
        Make a label (color- black)
        Parameters:
        s - Text
        f - Font
      • HLabel

        public HLabel(String s)
        Make a label with default attributes
        Parameters:
        s - text
      • HLabel

        public HLabel(String s,      double x,      double y)
        Make a label with specific coordinated in the data system
        Parameters:
        s - Text
        x - Position in X
        y - Position in Y
      • HLabel

        public HLabel(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 text of the label.
        Parameters:
        s - new text for the label
      • getText

        public String getText()
        Get the 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
      • getColor

        public Color getColor()
        Get color of a label.
        Returns:
        the color used to draw the label
      • setFont

        public void setFont(Font f)
        Sets the font to a specific value
        Parameters:
        f - font used to draw the label
      • getFont

        public Font getFont()
        Get the font of the label text.
        Returns:
        the font used to draw the label
      • setRotation

        public void setRotation(double r)
        Sets the rotation angle. Although all kind of angles (in PI-units) are allowed, internally we only use the interval 0-2pi hence we take care of all other cases.
        Parameters:
        r - angle for this label
      • getRotation

        public double getRotation()
        Returns the rotation angle.
        Returns:
        angle for this label
      • setLocation

        public void setLocation(double x,               double y)
        Sets the location of the label in the NDC 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
      • getGraphLabel

        public jplot.GraphLabel getGraphLabel()
        Get a label with default attributes
        Returns:
        get GraphLabel
      • doc

        public void doc()
        Show online documentation.
