![]() ![]() ![]() When creating a strategic business plan, or when undertaking a new project, a Gantt Chart is always present. In very simple terms, a Gantt Chart shows which tasks need to be completed and when they must be completed. It is used in project management for illustrating tasks or activities in relation to time. You don’t need to squint too hard to see that the month between 1 February and 1 March is shorter than the months between 1 January and 1 February and between 1 March and 1 April.A Gantt Chart is a bar chart used for visually representing a project’s schedule. There’s our Gantt chart with gridlines and axis labels at the first of each month. The formula in the third column links to the first, but the cells are formatted not as a Date but as General. The Axis Scale data has the first and last dates in the first column, dummy values of zero in the second column, and serial numbers of the dates in the third column. The Gantt data has Task names, Start dates, Duration, and End dates only the first three columns are needed. On the left is the data needed to create the Gantt chart itself, and on the right is the data for the axis scale. It’s a lot of steps, but not too complicated, and for the most part, the order you apply them is immaterial. We need to create a chart with bar chart series to display the Gantt chart bars, and we need to combine this with a line chart to produce the date axis with the desired tick spacing. Sometimes different chart types can share incompatible axis types, but here we are not so lucky. Excel uses this setting and adds the appropriate number of days, 31, 30, 29, or 28, so the tick labels are one month apart. The major unit (axis tick spacing) in the bar chart is 31, which is only appropriate for some months, while in the line chart it is 1 month. In the bar chart, the minimum and maximum are the numbers 4341, which are the serial numbers of the min and max dates in the line chart, and. ![]()
