Как добавить chart в windows forms

In this walk-through, you will learn how to create a graph using the Windows Form App (WinForm) step by step.

By default, chart control is not available in the toolbox. You have to install first the chart option, then proceed towards CHART preparation.

Create Project using template “Windows Forms App”

Select Your Framework .Net Version and create the project.

Search the Chart in the toolbox, you will come to know that there is no CHART control.

Install NugGet: System.Windows.Forms.DataVisualization

Right-click on Project and select Manage NuGet packages.

After installation, you can seethe Chart option is visible. Now, drag and drop the chart control on the Form1 canvas.

Double-click on the Form1 canvas area or press F7 on Form1 and enter the following code using the Inside Form1_Laod method.

private void Form1_Load(object sender, EventArgs e)
{
    this.Text = "How to Create Chart WinForm .NET 8";

    // Clear ChartAreas, Series
    chart1.ChartAreas.Clear();
    chart1.Series.Clear();

    // Create Chart Area
    ChartArea chartArea = new ChartArea("GraphArea");
    chartArea.AxisX.Title = "Months";
    chartArea.AxisY.Title = "Rs. In Lakhs";

    // Add Chart Area
    chart1.ChartAreas.Add(chartArea);

    // Create a Series and set type to Bar
    Series series = new Series("Sales")
    {
        ChartType = SeriesChartType.Bar,
        IsValueShownAsLabel = true
    };

    // Add Data Points
    series.Points.AddXY(1, 150);
    series.Points.AddXY(2, 70);
    series.Points.AddXY(3, 90);
    series.Points.AddXY(4, 150);
    series.Points.AddXY(5, 170);
    series.Points.AddXY(6, 90);
    series.Points.AddXY(7, 130);
    series.Points.AddXY(8, 70);
    series.Points.AddXY(9, 190);
    series.Points.AddXY(10, 120);
    series.Points.AddXY(11, 90);
    series.Points.AddXY(12, 70);

    // Add Series to Chart
    chart1.Series.Add(series);

    // Set Fonts
    series.Font = new Font("Verdana", 11);
    chart1.ChartAreas[0].AxisY.LabelStyle.Font = new Font("Segoe UI", 9);
}

Output

To change the Chart Type, set the following property.

// Create a Series and set type to Bar
Series series = new Series("Sales")
{
    ChartType = SeriesChartType.Line,
    IsValueShownAsLabel = true
};

Доброго времени суток! В данной статье мы рассмотрим, как можно создавать графики в WinForms C#.
В качестве платформы примера нужно взять .Net Framework 4.8. Далее в ссылки проекта необходимо добавить
ссылку на сборку System.Windows.Forms.DataVisualization.
Для этого нужно в обозревателе решений нажать правой мыши на элемент меню Ссылки и далее Добавить ссылку.
В открывшемся окне необходимо найти сборку и выделить ее галочкой. В панели элементов должен появиться новый элемент — Chart.
Обратите внимание, что проект должен быть для версии .Net Framework 4.*.
Теперь рассмотрим пример кода:


using System.Windows.Forms;
using System.Windows.Forms.DataVisualization.Charting;

namespace ChartsWinForms
{
    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();

            string[] daysOfWeek = { "Понедельник", "Вторник", "Среда", "Четверг", "Пятница", "Суббота", "Воскресенье" };
            int[] numberOfVisitors = { 1200, 1450, 1504, 1790, 2450, 1900, 3050 };

            // Установим палитру
            chart.Palette = ChartColorPalette.SeaGreen;

            // Заголовок графика
            chart.Titles.Add("Посетители");

            // Добавляем последовательность
            for (int i = 0; i < daysOfWeek.Length; i++)
            {
                Series series = chart.Series.Add(daysOfWeek[i]);

                // Добавляем точку
                series.Points.Add(numberOfVisitors[i]);
            }

        }

    }
}

Таким образом, вот так просто можно создавать графики в WinForms C#.

VS2022 — VS2019 .NET CHARTING COMPONENT Winforms 4.8 Framework C# Walk Through

ProEssentials WinForms interfaces are used when creating stand-alone Desktop or Embedded EXEs to be distributed royalty-free and ran on an end-users machine. This VS2022 — VS2019 C# Charting Walk-through includes instructions for Net4.8 Framework VS2022 and VS2019. If you prefer Net80 Nuget: Click here for Net80 Nuget Charting or if you prefer Visual Basic: Click here for VB.NET Charting or for C# in an earlier VS: Click here for VS2015-VS2012

See the demo…

• If you haven’t seen the v10 demo?
• Download our Winforms C# Chart Demo + WPF Demo + 100% native MFC Demo.
• Only Experience equals Knowledge: Size, Shape, Right Click, Export, Zoom (especially date and log scales), Pan, and Rotate.

Hello World — Walk Through — Tutorial

The WinForm interfaces support adapting to changes in the parent form’s font and background color. They are designed so that the grid number text size (grid numbers are the grid line labels such as 70, 80, 90 along y axis) matches that of the other standard controls such as TextBox, Radio Button, and Labels. As long as you don’t explicitly change the font and background color for the chart, you will be able to change the form’s font size and backcolor and all other controls on the form will adapt to match. Note that the default form text size of 8 points is fairly small. You may want to increase it to 9 or 10 points depending on your needs. This feature results in a clean looking user interface where the charting control appears to be a true sibling of the other standard controls.

You will have to write a little code (see below) to develop your graphing solutions. In the end, you’ll prefer our .NET (property, method, event) interface. 99% of your code will set simple properties.

Creating a new project…

1) Start Visual Studio.NET and create a new project targeting [C#] [Windows] [Desktop] and [WinForms .Net Framework]. Accept the default name of [WindowsFormsApp1]. Note, Do not select Windows Forms .NET (without the Framework) as the Framework is required and we recommend .Net 4.8 for this tutorial. We optionally have assemblies for Net80 (Windows) but these are installed via Nuget package via Package Manager and adjusting Package Source to [ Gigasoft10 (Local) ] or searching for «Gigasoft» if installing from Nuget.org.

2) When the new project opens, you will be presented the design view of «Form1.cs».

Adding designer controls to your Toolbox…

3) Installing WinForms interfaces into Visual Studio.NET

Pro Tip: To add an assembly to a modern VS2022 project, we recommend opening and editing the project file directly to add or adjust the Reference and HintPath manually. This approach simplifies the process and eliminates the tedious task of installing tools into the IDE. Once you start adding assemblies manually, you’ll likely find it avoids much of the confusion often associated with installing tools into the IDE.

VS2019 Instructions

Adding ProEssentials to the Form…

4) Double click the [Pego] tool within the toolbox. This places an instance of the Pego component within «Form1.cs».

Left click bottom-right corner of control and drag down-right to fill up client area of Form1. The adjacent image shows what you see.

This represents the default state of a ProEssentials Graph. The default state has one subset with four data points. In the course of constructing your own charts, you’ll set the properties PeData.Subsets and PeData.Points which define the quantity of data your chart will hold. You’ll then pass data via the PeData.Y[subset, point] two dimensional property array.

ProEssentials uses the terms Subsets and Points but you can think of these as Rows and Columns. Passing data is as simple as filling each Subset with Points worth of data.

To enable the chart to match the size of it’s container, let us change the chart’s Dock setting.

Adjusting design time settings…

Form1.cs [Code]…

6) Double click Form1’s Title/Caption Bar to open the code view for «Form1.cs» with default Form1_Load event initialized.

The cursor will be within the Form1_Load code section, enter the following code into this section.

You can copy and paste, but hand-typing a few lines of this code will help familiarize yourself with the Gigasoft.ProEssentials namespace.  

Note: adding the following using declaration at the top of «Form1.cs» will shorten enumeration syntax.
using Gigasoft.ProEssentials.Enums;

Your project code should look similar to…

Adding a DataHotSpot event…

7) The code above enabled the DataHotSpot event, so we should place some appropriate code in the DataHotSpot event.

Left click the pego control within Form1 to give it the focus.

From the main menu select [View] and [Properties Window]

Within the [Properties Window], click the event icon.

Within the available events, double-click PeDataHotSpot

This opens the code view of «Form1.cs» with cursor within the pego1.PeDataHotSpot event handler.

Картинка с сайта: www.gigasoft.com

Add the following code to the pego1.PeDataHotSpot event.

System.Windows.Forms.MessageBox.Show(«Subset » + e.SubsetIndex.ToString() +
«, Point » + e.PointIndex.ToString() + » with a value of » +
pego1.PeData.Y[e.SubsetIndex, e.PointIndex].ToString());

Success!!!

Save and run the project. Your project will show an image as follows. Move the mouse over a bar and click to trigger the DataHotSpot event.

This completes this walkthrough.

Please read the remaining sections within Chapter 2 and review the demo code and documentation that’s installed with the eval/product.

Once installed, the demo program can be accessed via shortcut…

Start / ProEssentials v10 / PeDemo

Note that our main charting demo is replicated in WPF and Winform C#.NET,  VB.NET, VC++ MFC, Delphi, Builder all accessible from where you installed ProEssentials.   These are great for modifying an existing demo to test potential modifications before implementing within your applications.

Example. Now we can use the Chart. In the next step, we will use the Form1_Load event handler to initialize the Chart we just added. To add Form1_Load, double-click on the Form window in Visual Studio.

Array: In Form1_Load, we assign an array of strings (Series) and an array of integers (Points).

For: In the for-loop, we add the strings to the Series collection and add the integers to the Points collections on those Series.

For

Tip: The loop results in two Series: a Cats series with a Point of 1, and a Dogs series with a Point of 2.

Info: These are reflected in a bar graph, which is shown in this page’s screenshot.

Example that sets Chart control up: C#

using System;
using System.Windows.Forms;
using System.Windows.Forms.DataVisualization.Charting;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
// Data arrays.
string[] seriesArray = { «Cats», «Dogs» };
int[] pointsArray = { 1, 2 };

// Set palette.
this.chart1.Palette = ChartColorPalette.SeaGreen;

// Set title.
this.chart1.Titles.Add(«Pets»);

// Add series.

for

(int i = 0; i < seriesArray.Length; i++)
{
// Add series.
Series series = this.chart1.Series.Add(seriesArray[i]);

// Add point.
series.Points.Add(pointsArray[i]);
}
}
}
}
