Explain the readi

The first step in reading a bar graph is to Know what does it represent. For this we read the caption which is generally written at the bottom of horizontal line x-axis and adjacent to vertical line y-axis.

After this we understand the scale of the graph in order to know the precise value of the given data.

After reading the bar graph, one must draw conclusions from it. Drawing various conclusions from a given bar graph is referred as the interpretation of the bar graph.
