public class BarScale
extends PointMethod

Title: BarScale

Description: This method is represented by a vertical scale without any labels and a slider pointing to the scale. The BarScale has an inner area (colored orange) which indicates the estimated probability. In other words, the height of this inner area corresponds to the estimated probability and changes when the slider is moved. For estimating a probability, the user can click at the desired position on the scale with the mouse or drag the slider with the mouse on the desired scale position. Changing the position of the slider also changes the height of the inner area. If the user thinks the probability to be elicited is 1, the inner rectangle has the same height as the baseline. If the user thinks the probability to be elicited is 0, the height of the inner rectangle is 0 and therefor you do not see the inner area of the scale. All other estimated probabilities are somewhere between these two extremes.

Method Detail

drawRectangles

public void drawRectangles()

Method for drawing the baseline of the scale and an inner rectangle of the scale. The baseline is represented by a rectangle and represents the scale-area on which can be clicked with the mouse. The height of the inner rectangle corresponds to the estimated probability and therefor changes when the slider is moved. If the user thinks the probability to be elicited is 1, the inner rectangle has the same height as the baseline. If the user thinks the probability to be elicited is 0, the height of the inner rectangle is 0 and therefor you do not see the inner rectangle. All other estimated probabilities are somewhere between these two extremes.

drawSlider

public void drawSlider()

Method for drawing a slider and an invisible slider. The sliders are both represented as polygons with a peak. The invisible slider overlaps the slider and represents the slide-area which can be dragged with the mouse.
