Gantt Chart in C#
Generate Gantt charts in C# with AddGantt and GanttTask — task bars on a time axis, per-task colours, rendered as self-contained SVG for reports and PDFs.
Gantt / Timeline
AddGantt() — horizontal task bars on a numeric time axis.
When to use a gantt chart
Reach for it when
- Project schedules and release plans, where overlap between tasks is what the reader is checking.
- Resource and occupancy timelines — anything with a start, an end, and a name.
- Embedding a schedule into a generated PDF or Word status report.
Use something else when
- Dependency networks. A Gantt shows position, not "B cannot start until A finishes".
- Very many tasks — past thirty rows it becomes a wall; group or filter first.
- Plans that change hourly, where a rendered snapshot is stale before it is read.
Gantt Chart in C#
Lifted verbatim from the chart types reference, so it compiles against the shipped API. See the API reference for every overload and the exact data types each series method accepts.
using TerraFluent.Chart.Reporting.Models;
string svg = ChartBuilder.Create()
.Title("Release Plan (weeks)")
.Size(760, 380)
.XAxis(x => { x.Title = "Week"; x.Min = 0; x.Max = 12; })
.AsAnimated()
.Series(s => s
.AddGantt("Schedule", new[]
{
new GanttTask { Name = "Design", Start = 0, End = 3 },
new GanttTask { Name = "Development", Start = 2, End = 8, Color = ChartColor.ChartBlue },
new GanttTask { Name = "Testing", Start = 7, End = 10 },
new GanttTask { Name = "Launch", Start = 10, End = 12, Color = ChartColor.ChartGreen },
}))
