How to use the ChartControl component in DEV.

The ChartControl is a commonly used data visualization tool used to create various types of charts such as line charts, bar charts, and pie charts. Here are some common uses of the ChartControl:

1. Input chart data:

// 创建一个Series对象
Series series = new Series("Series1", ViewType.Line);

// 添加数据点
series.Points.Add(new SeriesPoint("Point1", 10));
series.Points.Add(new SeriesPoint("Point2", 20));
series.Points.Add(new SeriesPoint("Point3", 30));

// 将Series对象添加到ChartControl的Series集合中
chartControl.Series.Add(series);

1. Customize the chart style:

// 设置图表的标题
chartControl.Titles.Add(new ChartTitle() { Text = "Chart Title" });

// 设置图表的背景色
chartControl.BackColor = Color.LightYellow;

// 设置图表的边框线颜色和宽度
chartControl.BorderOptions.Color = Color.Red;
chartControl.BorderOptions.Thickness = 2;

1. Set up the chart axis:

// 设置X轴的显示格式
chartControl.Series[0].ArgumentScaleType = ScaleType.Qualitative;
chartControl.Series[0].ArgumentDataMember = "XValue";

// 设置Y轴的显示格式
chartControl.Series[0].ValueScaleType = ScaleType.Numerical;
chartControl.Series[0].ValueDataMember = "YValue";

1. Choose a chart type:

// 设置图表类型为折线图
chartControl.Series[0].ChangeView(ViewType.Line);

// 设置图表类型为柱状图
chartControl.Series[0].ChangeView(ViewType.Bar);

// 设置图表类型为饼图
chartControl.Series[0].ChangeView(ViewType.Pie);

1. Add a legend:

// 创建一个图例对象
Legend legend = new Legend();

// 设置图例的位置
legend.DockTarget = chartControl;
legend.AlignmentVertical = LegendAlignmentVertical.TopOutside;
legend.AlignmentHorizontal = LegendAlignmentHorizontal.Right;

// 将图例添加到ChartControl的Legends集合中
chartControl.Legends.Add(legend);

These are just some basic uses of ChartControl, further customization options include setting the style of the chart, adding data labels, setting animation effects, and more. For more detailed information, refer to the official documentation or relevant tutorials for ChartControl.
