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. a vertical bar chart is sometimes called a column chart. some bar graphs present bars clustered in groups of more than one, showing the values of more than one measured variable. many sources consider william playfair (1759-1824) to have invented the bar chart and the exports and imports of scotland to and from different parts for one year from christmas 1780 to christmas 1781 graph from his the commercial and political atlas to be the first bar chart in history.  bar graphs/charts provide a visual presentation of categorical data. in a column (vertical) bar chart, categories appear along the horizontal axis and the height of the bar corresponds to the value of each category.
bar charts have a discrete domain of categories, and are usually scaled so that all the data can fit on the chart. bar graphs can also be used for more complex comparisons of data with grouped (or “clustered”) bar charts, and stacked bar charts. for example, a business owner with two stores might make a grouped bar chart with different colored bars to represent each store: the horizontal axis would show the months of the year and the vertical axis would show revenue. alternatively, a stacked bar chart stacks bars on top of each other so that the height of the resulting stack shows the combined result. grouped bar charts usually present the information in the same order in each grouping. variable-width bar charts, sometimes abbreviated variwide (bar) charts, are bar charts having bars with non-uniform widths.

a bar chart in sample is a type of document that creates a copy of itself when you open it. The doc or excel template has all of the design and format of the bar chart in sample, such as logos and tables, but you can modify content without altering the original style.

bar chart in guide
a bar chart is a way of summarizing a set of categorical data (continuous data can be made categorical by auto-binning). the height of each bar is proportional to a specific aggregation (for example the sum of the values in the category it represents). it is also possible to color or split each bar into another categorical column in the data, which enables you to see the contribution from different categories to each bar or group of bars in the bar chart. you can also view these color categories side-by-side as in the bar chart below.
another way to get a similar appearance is to add the column category to the category axis to create a hierarchy on that axis. note that in some cases the category axis is referred to as x-axis, and the value axis is referred to as y-axis. all visualizations can be set up to show data limited by one or more markings in other visualizations only (details visualizations). another alternative is to set up a bar chart without any filtering at all.
a bar chart is a statistical approach to represent given data using vertical and horizontal rectangular bars. a bar chart is a representation of numerical data in pictorial form of rectangles (or bars) having uniform width and varying heights.” bar charts are one of the means of data handling in statistics. she wants to display the data of cakes by representing the given information on a bar chart so that she can visually understand which type of cake she purchased the most. further, the vertical and horizontal bar charts are classified as: a bar chart is mostly used to represent the data in statistics formation. draw the bar chart to represent the data. in statistics, a bar chart (or bar graph) is a pictorial representation of data in quantities.
the length of each rectangular bar horizontal (or vertical) is equivalent to the data that it represents. in both cases, the height of the bars is according to the relative frequency of the numbers of data given in the element. there are two types of bar charts: vertical bar chart and horizontal bar chart. each rectangular bar in the graph represents a whole. a line chart is a graph or chart that is used to show information when a series of data is connected by a line whereas a bar chart is a particular way of representing data using rectangular bars where the height of each bar is proportional to the value they show in data. the difference between histograms and bar charts is that bars in a bar chart are not adjacent to each other. in a bar chart, it is necessary to provide equal spacing between the two bars whereas in a histogram bars are attached to each other and the x-axis shows the continuous data in terms of numbers.
bar charts show the frequency counts of values for the different levels of a categorical or nominal variable. for a pareto chart, the bars are ordered from highest to lowest. you may wish to consult a statistician or the many books and websites available to determine which type of bar chart works best for your data. figure 5 shows the same data with longer labels for the flavors in a horizontal chart. other options are to use a different color to highlight the bar for cherry.
the bar chart simply shows another bar for the category with very few (or very many) values in the bar. if there are groups in your data, plotting all the data together in a bar chart can help show patterns across these groups. with a stacked bar chart, you show the responses for your groups, which are the factories for the candy data. for the candy data, the counts of flavors will be stacked with the bar for each factory. also, as figure 15 shows, when adding labels, you need to be sure that the label can be read with the background color for each element of the stacked bar. bar charts do not make sense for continuous data, since they are measured on a scale with many possible values.
each bar’s height corresponds to a numeric value, which is measured by the y-axis. for example, the category variable is set to statename for a county dataset with a count aggregation method. for example, the category variable is set to statename for a county dataset with a count aggregation method and a split by field of electionwinner.
you can customize the dimensions of a grid chart layout by setting the mini charts per row numeric input. setting a y-axis bound can be used as a way to keep the scale of your chart consistent for comparison. you can configure the look of your chart by formatting text and symbol elements, or by applying a chart theme. the following sort options are available for bar charts: labels displaying the value of each bar or series can be turned on by checking label bars on the data tab in the chart properties pane.
