Create chart with Chart.js in Blazor

This library is a wrap around Chart.js for using it with Blazor WebAssembly and Blazor Server. The components is build with .NET6.

Installation

Fist, you have to add the component from NuGet. Then, open your index.html or _Host and add at the end of the page the following scripts:

<script src="_content/PSC.Blazor.Components.Chartjs/lib/Chart.js/chart.js"></script>
<script src="_content/PSC.Blazor.Components.Chartjs/Chart.js"></script>

The first script is the Chart.js library version 3.7.1 because I'm using this version to create the components. You can use other sources for it but maybe you can face issues in other versions.

Then, open your _Imports.razor and add the following:

@using PSC.Blazor.Components.Chartjs
@using PSC.Blazor.Components.Chartjs.Enums
@using PSC.Blazor.Components.Chartjs.Models
@using PSC.Blazor.Components.Chartjs.Models.Common
@using PSC.Blazor.Components.Chartjs.Models.Bar
@using PSC.Blazor.Components.Chartjs.Models.Bubble
@using PSC.Blazor.Components.Chartjs.Models.Doughnut
@using PSC.Blazor.Components.Chartjs.Models.Line
@using PSC.Blazor.Components.Chartjs.Models.Pie
@using PSC.Blazor.Components.Chartjs.Models.Polar
@using PSC.Blazor.Components.Chartjs.Models.Radar
@using PSC.Blazor.Components.Chartjs.Models.Scatter

There is a namespace for each chart plus the common namespaces (Enum, Models and the base).

Add a new chart

In your page you can create a new chart adding this code

<Chart Config="_config1" @ref="_chart1"></Chart>

In the code section you have to define those variables:

private BarChartConfig _config1;
private Chart _chart1;

Then, you can pass the configuration for the chart into _config1 (in the example code above). For a bar chart, the configuration is

_config1 = new BarChartConfig()
{
    Options = new Options()
    {
        Plugins = new Plugins()
        {
            Legend = new Legend()
            {
                Align = LegendAlign.Center,
                Display = false,
                Position = LegendPosition.Right
            }
        },
        Scales = new Dictionary<string, Axis>()
        {
            {
                Scales.XAxisId, new Axis()
                {
                    Stacked = true,
                    Ticks = new Ticks()
                    {
                        MaxRotation = 0,
                        MinRotation = 0
                    }
                }
            },
            {
                Scales.YAxisId, new Axis()
                {
                    Stacked = true
                }
            }
        }
    }
};

Then, you have to define the Labels and the Datasets like that

_config1.Data.Labels = BarDataExamples.SimpleBarText;
_config1.Data.Datasets.Add(new Dataset()
{
    Label = "Value",
    Data = BarDataExamples.SimpleBar.Select(l => l.Value).ToList(),
    BackgroundColor = Colors.Palette1,
    BorderColor = Colors.PaletteBorder1,
    BorderWidth = 1
});

The result of the code above is this chart
