The distribution of pacing states (PR, PV, AR, AV or PVE), sensor indicated pacing rates or other data based on data collected by event counters and displayed in a bar graph format by the programmer and based on data collected by event counters.
a graph which represents the frequency distribution for a set of data with rectangles having heights to represent the frequencies and widths to represent the data intervals; a histogram looks similar to a bar graph except there are no spaces between the rectangles or bars
Graph in which data are presented as a series of bars alongside each other.
(n) A visualization technique used to summarize data by reporting the number of data points that fall within a certain range of values. Histograms are often represented as bar graphs. Because histograms provide only a summary, they depict the original information only indirectly.
A bar graph analysis tool that can be used to identify contrast and dynamic range of an image. Histograms are found in the more advanced digicams and software programs (graphic editors) used to manipulate digital images. The histogram shows a scale of 0 - 255 (left to right) with 0 being black and 255 being white.
A chart that displays data in distribution, generally in graph format. It may be used to reveal the variation that any process contains.
A multiple-bar diagram representing the frequency distribution of a group as a function of some variable. The frequency of each class is proportional to the length of its associated bar.
Bar graph of the frequency distribution, with score limits on the horizontal axis and frequency of cases on the vertical axis
Graph in which rectangles are used to represent frequencies of observations within each interval.
a chart that represents the number of pixels within an image that have the same intensity values. The Y axis is the number of pixels per value which is charted on the X axis
a graph obtained by dividing the range of the data set into equal intervals and plotting the number of data points in each interval.
Allows you to see the exposure over a grayscale range also known as dynamic range. This will show you the level of brightness for each pixel and will tell you if your picture is over-exposed, under-exposed or normal.
a graphic display of a frequency table using rectangular bars with heights equal to the frequency in a particular class.
a graph representing the data produced by the flow cytometer. Both x- and y-axes indicate increasing brightness of fluorescence of the markers attached to the cells.
A graphic summary of variation in a set of data. The pictorial nature of the histogram lets people see patterns that are difficult to detect in a simple table of numbers. The histogram is one of the "seven tools of quality."
A graph that describes the grayscale distribution among all the pixels of an individual image. A histogram can be used to discern shadows, highlights, and distribution within the midtones.
A graph showing the relative distribution of PIXELS of various densities in an image. The histogram shows the number of pixels with high density on the left and low density on the right. Its purpose is to show the distribution of tone throughout an image. An image with no shadows will have a histogram with a valley on the left; a histogram with no hilights will have a valley on the right. The histogram below shows an image with a good deal of shadows, MIDTONES, and hilights, but less QUARTERTONES.
A statistical analysis of the number of pixels at each brightness level in an image.
A graph, or diagram showing the statistical distribution of values on a map, where the height of a column represents the frequency and the base represents categories as time intervals.
A graphic representation of a frequency distribution.
Two dimensional graph of data (i.e., content vs. cell number)
A univariate frequency diagram in which rectangles proportional to the area to the Class Frequencies are erected on contiguous sections of the horizontal axis, the width of each section representing the corresponding class interval of the variate.
A graph of the numbers of pixels at each brightness level in an image
Diagram or image showing frequency distribution -- shows number of values which fall into contiguously defined classes (value ranges).
A bar graph showing the frequency in each class using class intervals of the same length.
A special form of 'column chart', particularly used in statistical applications, using vertical columns to display the value of the data point or the average value of a range of data points in a limited set of classes.
A graph that traces the levels of red, blue, green and luminance throughout the image. All four value components should be evenly distributed across the graph. Unchecking one or more of the values turns off the trace for that value. There are two commands, Equalize and Stretch available from the Colors Menu (sub) Histogram Functions. The Equalize Command will average the traces in the Histogram and should smooth the image. The Stretch Command spreads out the image luminance similar effect as Brightness/Contrast.
In image processing, a representation of a frequency distribution of gray levels by means of rectangles whose widths represent class intervals and whose heights represent a corresponding number of pixels for a given gray level.[Go to Top of Page
Graphic representation of frequency of distribution of a continuous variable. It is used to describe the outbreak throughout time.
A diagram composed of a number of rectangles drawn adjacent to each other such that the area of each rectangle is proportional to the frequency of observations in the class interval represented by the width of the rectangle.
A way of expressing the frequency of occurrence of values in a data set within a series of equal ranges or bins, the height of each bin representing the frequency at which values in the data set fall within the chosen range. A cumulative histogram expresses the frequency of all values falling within a bin and lower in the range. A smooth curve derived mathematically from a histogram is termed the probability density function.
a graphic presentation of frequency of a phenomenon.
A representation of data by vertical bars, the heights of which indicate the frequency of energy or time events.
An analysis tool consisting of a bar graph that can be used to identify contrast and dynamic range image problems. Histograms are found in high-end imaging software used to manipulate digital images.
A graphic display of planned and or actual resource usage over a period of time. It is in the form of a vertical bar chart, the height of each bar representing the quantity of resource usage in a given time unit. Bars may be single, multiple, or show stacked resources.
a visual representation used for grouped data for a numerical variable. The histogram consists of adjacent rectangles, each standing on a class interval. The area of each rectangle is proportional to the frequency of observations falling in a class interval. Class intervals are often on the horizontal axis and all have the same width; the rectangles are vertical. Frequency density is read on the vertical axis. A bar graph is not a histogram.
a bar chart representing a frequency distribution; heights of the bars represent observed frequencies
a bar chart in which the data are organized into groups (intervals of the continuous possible outcomes)
a bar chart of an interval variable
a bar chart that plots the number of occurrences that fall into each of several bins or categories
a bar chart with no spaces between bars
a bar graph in which each bar represents some particular variable, and the height of each bar represents the number of cases of that variable
a bar graph of frequencies of different numerical values within a population
a bar graph on which the bars are adjacent to each other with no space between them
a bar graph that provides a picture or description of scores
a bar graph without spaces between the bars used for continuous data

a basic graphing tool that displays the relative frequency or occurrence of continuous data values showing which values occur most and least frequently
a chart, a visual representation, of the commonness of each tone in an image
a chart in which data values are counted and placed into buckets, each bucket counts the number of data items that fall into it's range, the buckets are then displayed in a bar chart
a chart like the one at the top of the next page
a chart of the weighted grade average distribution for each class
a chart that illustrates the distribution of pixel levels (densities)
a chart that is similar to a bar chart, but it is used for interval and ratio level variables
a chart (usually a simple column chart) that takes a collection of measurements and plots the number of measurements (called the frequency ) that fall within each of several intervals (called bins )
a column chart which shows the distribution of a population's values over the range of values
a diagram which consists of rectangles with areas proportional to the relative frequencies of the classes
