This quick tutorial explains the process to create Gantt chart in Excel using C#. It has the IDE settings, a list of instructions, and a sample code to develop Gantt chart in Excel using C#. You will get detailed code where sample code is created programmatically to demonstrate the complete process without any external data source.

Steps to Build a Gantt Chart in Excel using C#

1. Set the environment to use Aspose.Cells for .NET to create a Gantt chart
2. Instantiate the license, create a new Excel file using the Workbook class , and rename the first sheet
3. Define the list of sample project tasks with start/finish dates for the Gantt chart
4. Set the table headers for work item, start, finish, Start offset, duration
5. Calculate the initial start date as a baseline and insert each task row with the offset and duration
6. Format the sheet columns to auto-fit the Start and Finish dates
7. Set the custom data ranges for task names, offset series, and duration series in the Gantt chart
8. Add a stacked bar chart, create floating bars by hiding the offset series, and set style for bars and legend
9. Reverse the category axis, set label for the value axis, set the plot styling, and save the resultant Workbook

The above steps describe the process to create Gantt chart. Create a workbook, set Gantt chart task table, and calculate the start offsets and durations using the earliest date to plot the timeline. Finally, insert a stacked bar chart, hide the offset series for creating the floating Gantt bars, set the basic styling, and save the Excel file.

Code to Construct a Gantt Chart using C#

This code demonstrates the process to create Gantt diagram using C#. For further improvisations, auto-fit the worksheet columns, freeze the header row, and apply a built-in table style to the data ranges for better visualization. Options are also available for adding data labels, customizing axis titles, and exporting a chart image to enhance presentation.
