Gantt Chart in Excel

When we start a new project or a company wants to launch a new product or maybe a developer wants to take a new task, all these things require time for every bit of steps involved and how does one keep track of this? The answer is the Gantt Chart.

But What is a Gantt Chart in Excel?

Henry L. Gantt an American Engineer came with a production tool in 1917 which provides a graphical interpretation of a schedule for specific tasks in a project. The horizontal bar chart which was developed by Henry L. Gantt is known as Gantt Chart. This tool helps a person to analyze what time is specified for which task.

A Gantt Chart is a bar chart with the horizontal axis representing the total time span of a project, while the vertical axis is for the specific tasks of the project. A person can have a clear interpretation of a project with the help of Gantt Chart.

Below is an Image of Gantt Chart in Excel.

How to Make a Gantt Chart in Excel?

Gantt Chart in Excel is very simple and easy to create. Let understand the working of Gantt Chart in Excel by some Examples.

Steps to Make Gantt Chart in Excel

For a Gantt Chart to illustrate a timespan for the task of the project we need a table for the tasks and time defined. For Example, I need to start a new classroom for teaching. Below are the steps which will follow.

1. Search for a place to open a class (Time allotted to me: 5 Days)
2. Finalize the deal for the place (Time allotted: 2 Days)
3. Purchase Furniture’s (Time Allotted: 2 Days)

After going through all the above three steps then I can start teaching to students. Assume the start date for the first task is today i.e. 30^th Nov. Lets make the table in Excel.

The table looks like this,

From the above table, it is clear that I can start teaching from 9^th of Dec after completing all the tasks. Now how do we show the above table in the Gantt Chart? Let us name this steps of making Gantt Chart process as “PROCESS” and bifurcate them in different steps:

• Go to Insert Tab.
• In the charts group, Go to Bar Charts and select 3-D stacked bar chart(we can choose either 2-D or 3-D, but 3-D gives better illustration so let us stick with it).

• We see a blank chart and we need to input values in it.

Right click on the chart and select “Select Data”.

• In the legend entries(Legend Entries means a data which is located on the right-hand side of the chart) we can see an add button.

• Click on it and an Edit series pops out.

• In the series name, select the date cell & in series values remove the default value and select the range of date.

• We need to add a new series so, we again go to add button and in series name, we will select “Time allocated” & in series value the range of Time allocated.

• After clicking ok, we are again back to our select data dialog box. In the horizontal axis, label click on an edit button.

• In the axis label range select all the tasks.

• We have all our data so we can select ok in the select data source tab and the chart looks like this,

• There is a problem in the chart, our tasks are not in order and our tasks start from 30-Nov not from 24-Nov. To Fix this click on Tasks and then right click and select “Format Axis”.

• In the right-hand side, a dialog box appears. Click on Categories in reverse order highlighted. This will arrange the tasks in the right order.

• Now the date isn’t the date we wanted. In excel, Date is in number format. In any blank cell type our start date and in the home tab in numbers group, it is by default selected as custom. Select a number and we see the number for our start date. Now right-click on a date in the chart and select format axis.

• In the right-hand side of the dialog box, there is a section of Minimum Bound Values which is the start point of our dataset by default. Change it with the number format of our date we want.

• Now our project has not yet been started but the blue bar shows the completion of the task so to remove that right click on the blue bar and go to format data series.

• In the Fill section select “No Fill”.

• Now we have prepared our first Gantt Chart.

Let us practice Gantt Chart with few Examples.
