Bar chart

Bar charts are a type of graph that displays measure for different categories of data. A bar graph may run horizontally or vertically. They have a discrete range and are usually scaled that all the data can fit on the chart. Bar charts grouped from the highest to lowest. The example depicts the market penetration of the four countries: Australia, Germany, Brazil and Argentina.

The different countries are the discrete categories of data. The categories are usually qualitative and in a column bar chart, the categories appear along the horizontal axis. The height of the bar corresponds to the value of category. Bar charts are one of the most used types of graph in presentations and reports because they are very easy to interpret und simple to read. The relationship between the x and y axes is easy to see and they are effective in presenting changes over time. Types of Bar Graphs:

Vertical Bar Graph

The most popular type of bar graph is the vertical bar graph. It´s very easy when presenting a series of data over time. The user can easily see the difference between two or more business quarter. A disadvantage of the vertical graph is that they do not leave much room at the chart if long labels are required. The vertical bar Graph may solve this problem. There is more room for longer labels.

Horizontal Bar Graph / Plot bar graph

The horizontal bar graph displays the values in a vector or matrix as horizontal bars. This type of bar graph is typically referred to a horizontal bar graph. The layout is similar to the vertical bar graph. When you have well defined zero point and both positive and negative values, you can easy show the negative and positive values.

Stacked Bar Graph / Composite bar graph

The stacked bar Graph can absorb a lot of information Stacked graphs display cumulative values, but they are hard to interpret. It may be best to use them in analysis and decide first whether the graph will be meaningful during the report. There is no right answer, see which one works for your data. It is better to use a line graph rather than adding the price of one business to the price of another, or adding the prices of products over a period.

Different Applications for creating stacked bar Graph

Tableau: Using Multiple Measures There is two possibilities to create a Stacked Bar Chart in Tableau

  1. Use a separate bar for each dimension
  2. Use a separate bar for each measure

Excel:

  1. Stacked column and stacked column in 3D
  2. 100% stacked column and 100% stacked column in 3D
  3. 3D column
  4. Cylinder, cone and pyramid
