A bar graph (also known as a bar chart or bar diagram) is a visual tool that uses bars to compare data among categories. A bar graph may run horizontally or vertically. The important thing to know is that the longer the bar, the greater its value. A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart. A bar graph shows comparisons among discrete categories. One axis of the chart shows the specific categories being compared, and the other axis represents a measured value. Construction Example When constructing a compound bar graph ,the following steps are followed. using suitable scale 5.Plot the cumulative values for each year 6.Use values for components to subdivide the cumulative bar 7.The subdivisions are placed in descending order with the longest at the bottom Bar graphs are also good tools for examining the relationship (joint distribution) of a categorical variable and some other variable. To create a bar graph where the length of the bar tells you the mean value of a quantitative variable for each category, just tell graph hbar to plot that variable. Composite bar graph; Another alternative for a bar graph with two independent variables is to have the bars stacked rather than side-by-side. This arrangement is useful when the summation of all the levels of the second independent variable is as or more important than the values for each level.
A compound bar chart is a graph which combines two or more types of information in one chart. It can also compare different quantities. A compound bar chart is a type of bar chart where columns can be split into sections to show breakdown of data. These bars are then shaded or coloured differently to indicate the different variables being compared. bar graph. noun. a graph using parallel bars of varying lengths, as to illustrate comparative costs, exports, birth-rates, etc.
These bars are then shaded or coloured differently to indicate the different variables being compared. Page 3. What is the difference between a normal bar chart 24 Apr 2017 The clear presentation of the bar chart allows for comparison between different values, but if you are comparing many different quantities, it may Compound Bar Graph - Skills A2 - Google Sites sites.google.com/site/skillsa229/compound-bar-graph Construction Example When constructing a compound bar graph ,the following steps are followed.

Grouped bar charts are a way of showing information about different sub-groups of the main categories. In the example below, a grouped bar chart is used to show the different schemes (sub-groups) by which different categories of household materials are recycled.
