Getting Started with LiveCharts

Setting up your development environment to use LiveCharts is straightforward, and accessing its source code enhances customization and understanding. This section guides you through the initial steps and helps you create your first chart.

Setting Up Your Environment

To use LiveCharts, ensure you have Visual Studio installed. Then, add the LiveCharts package, a geared package designed for dynamic data visualization, to your project. You can do this via the NuGet Package Manager. Search for LiveCharts and install the latest version. This process adds all necessary references to your project.

Your First Chart with LiveCharts

Creating your first chart involves a few simple steps. First, add a chart control to your application's UI. If you're using WPF, you can do this in XAML or programmatically in C#.

Here's a basic example in XAML:

<lvc:CartesianChart Series="{Binding MySeries}"/>

<lvc:CartesianChart Series="{Binding MySeries}"/>

'INSTANT VB TODO TASK: The following line uses invalid syntax:
'<lvc:CartesianChart Series="{Binding MySeries}"/>

In your C# code, prepare the data for your chart. For a basic line chart, you'll need a SeriesCollection. You can populate this collection with LineSeries, setting the Values to your data points.

public SeriesCollection MySeries { get; set; }
public MainWindow()
{
    InitializeComponent();
    MySeries = new SeriesCollection
    {
        new LineSeries
        {
            Values = new ChartValues<double> { 4, 6, 5, 2, 7 }
        }
    };
    DataContext = this;
}

public SeriesCollection MySeries { get; set; }
public MainWindow()
{
    InitializeComponent();
    MySeries = new SeriesCollection
    {
        new LineSeries
        {
            Values = new ChartValues<double> { 4, 6, 5, 2, 7 }
        }
    };
    DataContext = this;
}

Public Property MySeries() As SeriesCollection
'INSTANT VB WARNING: The following constructor is declared outside of its associated class:
'ORIGINAL LINE: public MainWindow()
Public Sub New()
	InitializeComponent()
	MySeries = New SeriesCollection
		From {
			New LineSeries With {
				.Values = New ChartValues(Of Double) From {4, 6, 5, 2, 7}
			}
		}
	DataContext = Me
End Sub

This code snippet creates a simple line chart. It displays a series of values on a Cartesian chart. Remember to set the DataContext of your window or control to ensure the chart binds to your data.

By following these steps, you'll have a basic chart up and running. This is just the beginning. LiveCharts allows for much more complex and interactive data visualizations.

Exploring LiveCharts Features

LiveCharts is not just about displaying static data. Its real power lies in its ability to update in real-time, react to data changes, and offer a wide range of chart types. This section delves into these capabilities, providing examples to help you grasp the concepts.

Understanding Data Binding and Updates

Data binding is a core concept in LiveCharts. It allows your charts to reflect changes in your data automatically. This feature is especially useful for applications that deal with dynamic data sources.

Consider an application tracking stock prices. As new data comes in, you want your chart to update. With LiveCharts, you just update the data source. The chart detects these changes and updates accordingly.

Here’s how you can bind a chart to a data source:

var myValues = new ChartValues<double> { 3, 4, 6, 3, 2 };
var lineSeries = new LineSeries
{
    Values = myValues
};
mySeries.Add(lineSeries);
// When data changes
myValues.Add(5); // The chart updates automatically

var myValues = new ChartValues<double> { 3, 4, 6, 3, 2 };
var lineSeries = new LineSeries
{
    Values = myValues
};
mySeries.Add(lineSeries);
// When data changes
myValues.Add(5); // The chart updates automatically

Dim myValues = New ChartValues(Of Double) From {3, 4, 6, 3, 2}
Dim lineSeries As New LineSeries With {.Values = myValues}
mySeries.Add(lineSeries)
' When data changes
myValues.Add(5) ' The chart updates automatically

Diving into Chart Types

LiveCharts supports various chart types, each suited for different kinds of data visualization needs. Here are a few examples:

• Line Series: Ideal for displaying trends over time.
• Pie Chart: Best for showing proportions in a dataset.
• Bar Chart: Useful for comparing quantities among different categories.

To create a pie chart, you would use the PieSeries class. Here's a quick example:

public SeriesCollection MyPieSeries { get; set; }
public MainWindow()
{
    InitializeComponent();
    MyPieSeries = new SeriesCollection
    {
        new PieSeries
        {
            Values = new ChartValues<double> { 4, 6, 5 },
            Title = "Series 1"
        },
        new PieSeries
        {
            Values = new ChartValues<double> { 7, 8, 6 },
            Title = "Series 2"
        }
    };
    DataContext = this;
}

public SeriesCollection MyPieSeries { get; set; }
public MainWindow()
{
    InitializeComponent();
    MyPieSeries = new SeriesCollection
    {
        new PieSeries
        {
            Values = new ChartValues<double> { 4, 6, 5 },
            Title = "Series 1"
        },
        new PieSeries
        {
            Values = new ChartValues<double> { 7, 8, 6 },
            Title = "Series 2"
        }
    };
    DataContext = this;
}

Public Property MyPieSeries() As SeriesCollection
'INSTANT VB WARNING: The following constructor is declared outside of its associated class:
'ORIGINAL LINE: public MainWindow()
Public Sub New()
	InitializeComponent()
	MyPieSeries = New SeriesCollection
		From {
			New PieSeries With {
				.Values = New ChartValues(Of Double) From {4, 6, 5},
				.Title = "Series 1"
			},
			New PieSeries With {
				.Values = New ChartValues(Of Double) From {7, 8, 6},
				.Title = "Series 2"
			}
		}
	DataContext = Me
End Sub

This code snippet sets up a basic pie chart with two data series. Like the line chart example, it binds the PieSeries to the Values property.

LiveCharts also offers flexibility and control over the appearance and behavior of your charts. You can customize nearly every aspect, from colors and labels to animations and interactivity. This makes it possible to tailor your charts to fit the look and feel of your application perfectly.

Introduction to IronPDF

Integrating LiveCharts with IronPDF bridges the gap between dynamic data visualization and static report generation. IronPDF is a powerful library for C# that allows developers to create, manipulate, and convert PDF documents programmatically.

Combining it with LiveCharts enables the creation of PDF reports containing your interactive charts. This section introduces IronPDF and guides you on how to set it up in your project.

Why IronPDF?

IronPDF's HTML to PDF Conversion Capabilities excel where other PDF libraries fall short, especially in its ability to render HTML to PDF. This feature is particularly useful when working with LiveCharts, as you can render your charts to HTML canvases and then convert these canvases into PDF documents. IronPDF supports full CSS3, JavaScript, and HTML5, ensuring that your charts look as intended in the PDF output.

LiveCharts with IronPDF

Here's a detailed code example that illustrates the process of creating a chart with LiveCharts, exporting it, and then using IronPDF to generate a PDF report that includes this chart. This example assumes you have a basic understanding of how to work with LiveCharts and IronPDF.

First, ensure you have the LiveCharts and IronPDF packages installed in your project via NuGet.

Step 1: Generate the Chart with LiveCharts

Let's start by creating a simple line chart using LiveCharts. For simplicity, this example will focus on generating the chart and saving it as an image, which will later be included in our PDF.

private void GenerateChartButton_Click(object sender, RoutedEventArgs e)
{
    CreateAndSaveChartImage();
}
public void CreateAndSaveChartImage()
{
    var seriesCollection = new SeriesCollection
{
    new LineSeries
    {
        Values = new ChartValues<double> { 4, 6, 5, 2, 7 },
        Title = "Sample Series"
        // Make sure to configure the series properties like color, point geometry, etc.
    }
};
    var chart = new CartesianChart
    {
        Series = seriesCollection,
        Width = 400,
        Height = 300,
        Background = Brushes.White
    };
    // Add chart to the UI
    ChartContainer.Child = chart;
    chart.Update(true, true); // Force chart redraw
    SaveChartToImage(chart);
}
private void SaveChartToImage(CartesianChart chart)
{
    // Ensure the chart layout is updated.
    chart.Measure(new Size(chart.Width, chart.Height));
    chart.Arrange(new Rect(0, 0, chart.Width, chart.Height));
    var renderTargetBitmap = new RenderTargetBitmap(
        (int)chart.ActualWidth,
        (int)chart.ActualHeight,
        96, // dpiX value
        96, // dpiY value
        PixelFormats.Pbgra32); // Pixel format
    renderTargetBitmap.Render(chart); // Render the chart to the bitmap
    var encoder = new PngBitmapEncoder();
    encoder.Frames.Add(BitmapFrame.Create(renderTargetBitmap));
    // Define the path where the chart will be saved
    string path = "chart.png";
    using (var stream = File.Create(path))
    {
        encoder.Save(stream);
    }
    MessageBox.Show($"Chart saved as {path}");
}

private void GenerateChartButton_Click(object sender, RoutedEventArgs e)
{
    CreateAndSaveChartImage();
}
public void CreateAndSaveChartImage()
{
    var seriesCollection = new SeriesCollection
{
    new LineSeries
    {
        Values = new ChartValues<double> { 4, 6, 5, 2, 7 },
        Title = "Sample Series"
        // Make sure to configure the series properties like color, point geometry, etc.
    }
};
    var chart = new CartesianChart
    {
        Series = seriesCollection,
        Width = 400,
        Height = 300,
        Background = Brushes.White
    };
    // Add chart to the UI
    ChartContainer.Child = chart;
    chart.Update(true, true); // Force chart redraw
    SaveChartToImage(chart);
}
private void SaveChartToImage(CartesianChart chart)
{
    // Ensure the chart layout is updated.
    chart.Measure(new Size(chart.Width, chart.Height));
    chart.Arrange(new Rect(0, 0, chart.Width, chart.Height));
    var renderTargetBitmap = new RenderTargetBitmap(
        (int)chart.ActualWidth,
        (int)chart.ActualHeight,
        96, // dpiX value
        96, // dpiY value
        PixelFormats.Pbgra32); // Pixel format
    renderTargetBitmap.Render(chart); // Render the chart to the bitmap
    var encoder = new PngBitmapEncoder();
    encoder.Frames.Add(BitmapFrame.Create(renderTargetBitmap));
    // Define the path where the chart will be saved
    string path = "chart.png";
    using (var stream = File.Create(path))
    {
        encoder.Save(stream);
    }
    MessageBox.Show($"Chart saved as {path}");
}

Imports System

Private Sub GenerateChartButton_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
	CreateAndSaveChartImage()
End Sub
Public Sub CreateAndSaveChartImage()
	Dim seriesCollection As New SeriesCollection
		From {
			New LineSeries With {
				.Values = New ChartValues(Of Double) From {4, 6, 5, 2, 7},
				.Title = "Sample Series"
			}
		}
	Dim chart = New CartesianChart With {
		.Series = seriesCollection,
		.Width = 400,
		.Height = 300,
		.Background = Brushes.White
	}
	' Add chart to the UI
	ChartContainer.Child = chart
	chart.Update(True, True) ' Force chart redraw
	SaveChartToImage(chart)
End Sub
Private Sub SaveChartToImage(ByVal chart As CartesianChart)
	' Ensure the chart layout is updated.
	chart.Measure(New Size(chart.Width, chart.Height))
	chart.Arrange(New Rect(0, 0, chart.Width, chart.Height))
	Dim renderTargetBitmap As New RenderTargetBitmap(CInt(Math.Truncate(chart.ActualWidth)), CInt(Math.Truncate(chart.ActualHeight)), 96, 96, PixelFormats.Pbgra32) ' Pixel format
	renderTargetBitmap.Render(chart) ' Render the chart to the bitmap
	Dim encoder = New PngBitmapEncoder()
	encoder.Frames.Add(BitmapFrame.Create(renderTargetBitmap))
	' Define the path where the chart will be saved
	Dim path As String = "chart.png"
	Using stream = File.Create(path)
		encoder.Save(stream)
	End Using
	MessageBox.Show($"Chart saved as {path}")
End Sub

Step 2: Create an HTML Template and Insert the Chart

Now, we'll prepare our HTML content, embedding the chart we just saved as an image.

string htmlContent = @"
<html>
<body>
    <h1>Chart Report</h1>
    <img src='chart.png' alt='Chart'>
    <p>This is a report generated by combining LiveCharts and IronPDF.</p>
</body>
</html>";

string htmlContent = @"
<html>
<body>
    <h1>Chart Report</h1>
    <img src='chart.png' alt='Chart'>
    <p>This is a report generated by combining LiveCharts and IronPDF.</p>
</body>
</html>";

Dim htmlContent As String = "
<html>
<body>
    <h1>Chart Report</h1>
    <img src='chart.png' alt='Chart'>
    <p>This is a report generated by combining LiveCharts and IronPDF.</p>
</body>
</html>"

Step 3: Convert HTML to PDF with IronPDF

Finally, we'll use IronPDF to convert our HTML content, including the embedded chart image, into a PDF document.

using IronPdf;
public void CreatePdfReport(string htmlContent)
{
    var renderer = new ChromePdfRenderer();
    var pdf = renderer.RenderHtmlAsPdf(htmlContent);
    pdf.SaveAs("Report.pdf");
}

using IronPdf;
public void CreatePdfReport(string htmlContent)
{
    var renderer = new ChromePdfRenderer();
    var pdf = renderer.RenderHtmlAsPdf(htmlContent);
    pdf.SaveAs("Report.pdf");
}

Imports IronPdf
Public Sub CreatePdfReport(ByVal htmlContent As String)
	Dim renderer = New ChromePdfRenderer()
	Dim pdf = renderer.RenderHtmlAsPdf(htmlContent)
	pdf.SaveAs("Report.pdf")
End Sub

Make sure to replace "chart.png" in the htmlContent string with the correct path to your chart image if it's not in the same directory as your application's executable.

This example covers a basic scenario to illustrate the process. Depending on your specific requirements, you might need to adjust the code, especially regarding how you handle and source images for your charts.
