Bar Graphs

How to Create a Bar Chart

Bar charts (bar graphs) are diagrams displaying data as horizontal or vertical bars of certain heights. Bar charts are widely used to show and compare the values of the same parameters for different data groups.
The bar graph can be vertical or horizontal. This depends on the number of categories. There are many methods in which bar graph can be built and this makes it a very often used chart type. Usually, a bar chart is created so that the bars are placed vertically. Such an arrangement means that the bar's height value is proportional to the category value. Nevertheless, a bar chart can be also drawn horizontally. This means that the longer the bar, the bigger the category. Thus, a bar chart is a good way to present the relative values of different measured items. The ConceptDraw Bar Graphs solution allows you to draw a bar chart quickly using a vector library, containing the set of various bar charts objects.

How to Draw a Histogram

Histogram is a diagram used to visualize data through bars of variable heights. Making histogram can be helpful if you need to show data covering various periods (hours, days, weeks, etc). When the vertical column of the histogram refer to frequency it shows how many times any event happens. It is a Frequency histogram. A bar chart diagram is similar to a histogram, but in contrast to a bar chart a histogram represents the number how many times there have been certain data values. You can use a histogram to depict continual data flow such as temperature, time, etc. You can effortlessly draw histograms using the Histograms solution for CnceptDraw DIAGRAM. Making a histogram can by very useful to represent various statistical data.
