Bar charts represent data in categories by arranging it in rectangular bars. The height of each bar is proportional to the value that bar is representing.
For instance, a bar representing the value 1000 will be taller or greater in length than a bar representing the value 500.
In Tableau, we can make different kinds of bar charts such as; Segmented bar chart, Stacked bar chart, Side-by-side bar chart etc.
1. Horizontal/ Vertical bar chart : A horizontal or vertical bar graph is a simple graph having bars of vertical or horizontal orientation.
2. Segmented bar chart : A segmented bar chart is a bar chart where a bar chart contains more than one set of bars.
Each set of bars belongs to a particular segment. For instance, we can have a sales bar graph for three or four different segments all seen in a single view.
- Stacked bar chart : A stacked bar chart has a single bar divided into smaller parts.
For instance, a single bar for the year 2019 can show sales for different countries or regions or cities.
We can also set a color scheme for the subdivisions in a bar as we can see in a stacked bar chart below.
- Side-by-side bar chart : A side-by-side bar chart will have multiple bars standing next to each other for a single segment.
Instead of stacking multiple values one upon the other like in stacked bar charts, this chart places them side-by-side.
