Installation via Package Manager Console

To integrate GunaCharts into your Visual Studio project using the Package Manager Console, follow these steps:

  1. Open your Visual Studio project.

  2. Go to Tools > NuGet Package Manager > Package Manager Console.

  3. In the Package Manager Console, enter the following command:

    Install-Package Guna.Charts.WinForms
  4. Press Enter to execute the command. The package will be installed into your project.

How to Use GunaCharts

  1. Begin by importing the required namespaces at the beginning of your Form class:

    using System; 
    using System.Drawing; 
    using System.Windows.Forms; 
    using Guna.Charts.WinForms;
  2. Create a new Form class that inherits from the Form class:

    public partial class Form1 : Form
        public Form1()
  3. Inside the Form class, declare the variables needed for GunaCharts:

    private GunaChart gunaChart;
    private GunaLineDataset gunaLineDataset;
    private GunaBarDataset gunaBarDataset;
  4. Implement the InitializeGunaChart method, where we set up both bar and line charts:

    private void InitializeGunaChart()
        // Create a new instance of GunaChart
        gunaChart = new GunaChart();
        gunaChart.Dock = DockStyle.Fill;
        // Set up GunaLineDataset
        gunaLineDataset = new GunaLineDataset();
        gunaLineDataset.Label = "Line";
        gunaLineDataset.LegendBoxFillColor = Color.DodgerBlue;
        gunaLineDataset.FillColor = Color.DodgerBlue;
        gunaLineDataset.BorderColor = Color.DodgerBlue;
        gunaLineDataset.YFormat = "Income {0:C}";
        // Set up GunaBarDataset
        gunaBarDataset = new GunaBarDataset();
        gunaBarDataset.Label = "Bar";
        gunaBarDataset.LegendBoxFillColor = Color.MediumSlateBlue;
        gunaBarDataset.YFormat = "C";
        // Add the datasets to the Datasets collection of GunaChart
        // Generate data and labels for the datasets
  5. Define the GenerateDataAndLabels method to populate the datasets with data:

    private void GenerateDataAndLabels()
        // Sample labels for the x-axis representing months
        string[] monthLabels = { "January", "February", "March", "April", "May", "June", "July" };
        // Generate random data for the datasets    
        var random = new Random();
        foreach (var label in monthLabels)
            gunaLineDataset.DataPoints.Add(new LPoint()
                Label = label,
                Y = random.Next(10, 100),
            gunaBarDataset.DataPoints.Add(new LPoint()
                Label = label,
                Y = random.Next(10, 100),
  6. Run your application.

Exporting Charts

Capture your visually appealing charts with GunaCharts' export feature. Simply:

  • Export the chart as an image using the save dialog::

  • Export the chart to a specific file path:

  • Export the chart with a specific image format (e.g., PNG):

    gunaChart.Export("C:\chart.png", System.Drawing.Imaging.ImageFormat.Png);

Activating Zoom Functionality

GunaCharts provides an immersive zooming experience to magnify specific chart areas for a closer analysis. You can enable and configure zooming with the following steps:

  • Activate Zoom Mode (Choose one): Zoom along the X-axis:

    gunaChart.Zoom = ZoomMode.X;

    Zoom along the Y-axis:

    gunaChart.Zoom = ZoomMode.Y;

    Zoom along both X and Y axes:

    gunaChart.Zoom = ZoomMode.XY;
  • To deactivate zoom functionality:

    gunaChart.Zoom = ZoomMode.None;

Zoom actions can be performed using the mouse wheel or pinch gestures if your device supports touch screen interaction. Additionally, the zoom functionality of GunaCharts can be achieved through various methods:

  • Zoom In:

  • Zoom Out:

  • Reset Zoom

Version 1.0.9

Stay updated with GunaCharts' latest enhancements and fixes via our release notes:

Bug Fixes:
1. Background Display Issue with Multiple Charts:
  Resolved an issue where the chart's background would display as blank or gray when multiple charts were used simultaneously. The fix ensures that the background renders correctly for all instances of the chart.
2. IndexLabel Location Beyond Scale Bounds:
  Addressed a bug that caused indexLabels to be incorrectly positioned beyond the scale bounds. This issue has been rectified, and indexLabels are now properly aligned within the scale boundaries.
3. Enhanced Update and Rendering Performance:
  Optimized the update and rendering process for improved performance. The chart now updates and renders more quickly, leading to a smoother user experience.
New Features:
1. Zoom Functionality:
  Introduced a new zoom feature that enables users to magnify specific areas of the chart. Three zoom modes are available: X, Y, and XY. To activate zoom, set the `Zoom` property on the `GunaChart` instance.
  GunaChart.Zoom = ZoomMode.X;

  Zoom actions can be performed using the mouse wheel or pinch gestures if your device supports touch screen interaction. Additionally, the zoom functionality of GunaCharts can be achieved through various methods:

2. Customizable Legend Box:
  Implemented the ability to customize the fill color and border color of the legend box. This feature can be configured for individual datasets.
  dataset.LegendBoxFillColor = Color.Red;
  dataset.LegendBoxBorderColor = Color.Black;

3. Number Formatting for Chart Values:
  Added support for formatting numerical values displayed on the chart. Users can specify number formats directly on the dataset.
  dataset.YFormat = "C";
  dataset.YFormat = "Car {0:C}";

4. Corner Radius for Bar and HorizontalBar Charts:
  Incorporated the ability to set corner radius values for Bar and HorizontalBar chart types directly on the dataset.
  BarDataset.CornerRadius = 5;

  Alternatively, automatic rounded corners can be enabled by setting `AutoRoundedCorners` to true.
  BarDataset.AutoRoundedCorners = true;

Happy charting!
