The Histogram dialog is used to track and analyze data based on a specified range of values. These values are represented graphically using the Histogram representation. The Sliders are used to comprise in that range on the required values. All the pixels (values) comprised in that range are highlighted on the image.
The Histogram graph is displayed using the Luminance algorithm which is required for histogram exploration and exact data distribution figures.
The Up/Down controls at the left of the graph are used to adjust the Vertical Scale of the histogram. The Sliders and text boxes are used to position the start and end points of the range. The Center Slider is used to move the ranger across the histogram.
