Simple or Non-Stacked Bar Chart
Simple or non-stacked bar charts are the most common type of the bar chart category. It is shown in horizontal forms, and is very helpful to present a set of data over a period such as quarterly sales or annual statistics. Readers can easily track the growth of data over a certain time and analyze the comparisons between different data groups. Groups of data are usually in different colors for readers to distinguish. The adequate space for the long bar length along the horizontal axis is good for categories with long titles.
Stacked Bar Chart
Sometimes it could be impractical to include all the comparisons only in a simple or non-stacked bar chart type. The stacked type can convey more data details for different categories than the traditional non-stacked types. Readers can find the development and values of dominant groups, and the trends for sub-groups for each category in a stacked bar chart. The overall length of a bar indicates the total size of a data category, and the various colors or markers are used for showing the percentages or numerical values of different sub-categories. The 100% bar chart type is shown in percentages.
