- It can be very confusing and frustrating to try to understand data when it is not organized in any logical way. Thankfully, there are tools and techniques that you can use to help you to make sense of it, visualize patterns and trends and interpret the information behind the numbers. In this article, we will show you how you can use tables and different types of graphs to help you achieve this.

- If you are asked to answer the following questions:
- In what year did the Unilever Group have the highest increase in revenue?
- In what year there was the biggest drop in revenue?
- Then you can add a couple of rows to the previous table to give you the information that you need. One row will contain the total revenue per year, and the other one will include the change in revenue between the current year and the previous one.
- The values in the Total revenue row in the table below, are the result of adding the revenue for all product segments per year, and the values in the Revenue change are the result of subtracting the total revenue from the previous year from the current one. For example, the values corresponding to Total revenue and Revenue change for the year 2011 are calculated as follows:
- The steps to draw a bar graph from a set of values on a table are as follows:
- Choose the scale, depending on the data range (minimum and maximum values), and decide what increments you will use to be able to display all the data;
- Draw the axes and label them;
- Draw a bar for each category. The length of each bar will depend on the values on the table;
- Choose a title for your graph, related to the relationship between the variables that the bar graph is representing.
- The steps to draw a line graph from a set set of values on a table are:
- Choose the scale;
- Draw the axes and intervals and label them;
- Plot a point on the graph for each value on the table;
- Connect each individual point with the one next to it using a straight line;
- Choose a title for your line graph.
- Let's now represent the same data used in
