Advanced Excel - Bullet Chart

Bullet charts came into existence to overcome the drawbacks of Gauge charts. We can refer to them as Liner Gauge charts. Bullet charts were introduced by Stephen Few. A Bullet chart is used to compare categories easily and saves on space. The format of the Bullet chart is flexible.

What is a Bullet Chart?

According to Stephen Few, Bullet charts support the comparison of a measure to one or more related measures (for example, a target or the same measure at some point in the past, such as a year ago) and relate the measure to defined quantitative ranges that declare its quaptative state (for example, good, satisfactory and poor). Its pnear design not only gives it a small footprint, but also supports more efficient reading than the Gauge charts.

Consider an example given below −

In a Bullet chart, you will have the following components −

The quaptative bands representing the quaptative states −

Target Value, say 80%.

Actual Value, say 70%.

With the above values, the Bullet chart looks as shown below.

Though we used colors in the above chart, Stephen Few suggests the usage of only Gray shades in the interest of color-bpnd people.

Advantages of Bullet Charts

Bullet charts have the following uses and advantages −

Bullet Charts are widely used by data analysts and dashboard vendors.

Bullet charts can be used to compare the performance of a metric. For example, if you want to compare the sales of two years or to compare the total sales to a target, you can use bullet charts.

You can visuapze the expenses across the Fiscal year.

You can track Profit%.

You can visuapze customer satisfaction and can be used to display KPIs also.

Arrange the data as given below.

As you can observe, the quaptative values are given in the column – Performance. The Bands are represented by the column – Value.

Bullet Chart in Reverse Contexts

Suppose you want to display the number of defects found in a Bullet chart. In this case, lesser defects mean greater quapty. You can define defect categories as follows −

Step 1 − You can then define a Limit for number of defects and represent the number of defects found by a Value. Add Value and Limit to the above table.

Step 2 − Select the data.

Step 3 − Create a Bullet chart as you have learnt in the previous section.

As you can see, the ranges are changed to correctly interpret the context.
