public class BarMeter extends JPanel
BarMeter presents a vertical, block-style meter to present numerical information as a fraction of a number of divisions (eg, progress or resource consumption). The default number of divisions is variable, but the default is 1. The meter represents inputted values as one of either color, one "Used" and the other "Un-Used." Used are filled in to the the percentage value inputted (integer) divided by the number of divisions. The default color used is Green, and default unused is Dark Grey.

    • paintComponent

      public void paintComponent(Graphics g)
      Draws the vertical bar, or all 100invalid input: '&#37' of posible amplitude values.
      Overrides:
      paintComponent in class JComponent
      Parameters:
      g - DOCUMENT ME!

    • setAmplitude

      public void setAmplitude(int amp)
      sets the height of the of the bar reading.
      Parameters:
      amp - percentage amount of the amplitude. ARguments greater than 100 (invalid input: '&#37') or less than zero are thrown out.

    • setDivisions

      public void setDivisions(int div)
      applies the given int to the total number of bars on the display.
      Parameters:
      div - sets the number of bars, or divisions, on the display. the finest resolution that may be displayed, is then 100/div (invalid input: '&#37').

    • setUnusedColor

      public void setUnusedColor(Color c)
      applies the given color to bars which are not lit and are above the set amplitude.
      Parameters:
      c - color used in divisions that represent values smaller than the amplitude.

    • setUsedColor

      public void setUsedColor(Color c)
      applies the given color to bars which are "lit" and are up to the set amplitude.
      Parameters:
      c - color used in divisions that represent values smaller than the amplitude.
