The XtraCharts suite provides a wide variety of different 2D chart types (also calledview types) which give you the ability to display data as any of the basic chart types, or even as a combination of different series views. In addition, if the data provided for a particular chart type is still valid for another chart type, you can change the current series view with a single click or line of code (see How to: Change the View of a Series). This makes the Chart Control more flexible and effective in representing data.
The topics listed in this section describe the 2D chart types available in XtraCharts, along with short descriptions on how to use them. The following 2D chart types are available:
|
A - F |
L - R |
R - S |
S |
|---|---|---|---|
Moreover, XtraCharts introduces a special chart type that uses an optimized algorithm for quick series rendering, to afford representation of avery large quantity of points:
Also note that with XtraCharts, it's possible to combine several 2D charts together into a single composite chart. Refer to theCombining Different Series Views document, for more information on composite charts.
而且，XtraCharts引入了一个特殊的图表类型，使用优化算法处理快速序列渲染，来满足大量点的一个显示：这就是Swift Plot（迅捷快速绘制）。
请注意：使用XtraCharts，可以在单一的组合图表中一起联合使用几种2D图表。欲了解更多组合图的信息，请参考Combining Different Series Views文档。
| Area Chart |  |
The Area Chart is represented by the AreaSeriesView object, which belongs to Area Series Views. This view displays series as filled areas on a diagram, with each data point displayed as a peak or hollow in the area. This view is useful when you need to show trends for several series on the same diagram, and also show the relationship of the parts to the whole.
面积图由AreaSeriesView对象表示，属于Area Series Views区域序列视图集.这种视图通过填充图中区域显示序列，每一个数据点被显示为区域中的一个峰值或空心。当你需要在同一个图表中展示几种序列趋势，并且显示部分和整体之间的关系时，区域图表将非常合适。
An Area chart is shown in the image below. Note that this chart type is based upon theXYDiagram, so it can be rotated to show bars either vertically or horizontally.
这幅图表的基类型是XYDiagram，所以可以被旋转显示为横型或竖型条形图。
The table below lists the main characteristics of this chart type.

| Bubble Chart | |
2、气泡图
The Bubble Chart is represented by theBubbleSeriesView object, which belongs to Point Series Views. This view, in addition to other point diagram capabilities, allows you to visually represent data that has a third dimension (it is theBubbleLabelValueToDisplay.Weight of a series point), expressed in a bubble's size. You map two dimensions along the usual X and Y axes, and then the third dimension is displayed as a shape (a filled circle - "bubble", or a star, triangle, etc.) at the data point. Also, you can specify the size of the smallest and largest marker for the chart, by using theBubbleSeriesView.MaxSize andBubbleSeriesView.MinSize properties of the series view.
气泡图由BubbleSeriesView对象表示，属于Point Series Views点序列视图集。这种视图，除了具有其他点状图表的功能外，还可以增加第三维（要显示值的气泡标签权重BubbleLabelValueToDisplay.Weight）通过气泡的大小来可视化的显示数据。只需映射传统的X和Y轴，第三维就会在数据点处显示为一个几何形状（一个填充圆-“气泡”，或者是星形，三角形等等）。你也可以通过设置序列视图的BubbleSeriesView.MaxSize and BubbleSeriesView.MinSize属性指定图表标记的最小和最大尺寸。
An example of the Bubble chart is shown in the image below. Note that this chart type is based upon theXYDiagram, so it can be rotated to change axis positions.
继承自XYDiagram，可以旋转改变轴的位置。

| Candle Stick Chart | |
3、烛台图表
The Candle Stick Chart is represented by theCandleStickSeriesView object, which belongs to Financial Series Views (also called Low-High-Open-Close).
烛台图表由CandleStickSeriesView对象表示，属于金融序列视图集（也被称为股票图 –最低-最高--开盘-收盘）
This view is used to show the variation in the price of stock over the course of a day. Each point consists of a rectangle (body the bottom and top values of which correspond to theOpen and Close prices) and a vertical line (shadow,wick ortail the bottom and top values of which correspond to theLow andHigh prices). If the stock closes higher than its opening price, the body is hollow. And if the stock closes lower than its opening price, the body is filled.
这个视图用来表示漫长的一天中股票价格的变化趋势。每一个点由一个矩形（矩形体 底部和顶部的值相当于股票价格中的开盘和收盘）和一条垂直线（影子，灯芯或尾巴 底部和顶部的值相当于股票中的最低最高价）组成。如果股票的收盘价高于开盘价，矩形体就是空心的。如果收盘价低于开盘价，矩形体就是实心的。
For Candle Stick charts, you can choose for which price level (Low, High, Open or Close) to enableFinancialSeriesViewBase.ReductionOptions, meaning that in case the specified price is lower in comparison to the previous point's value, the subsequent point is painted red (or any other color).
对于阴阳烛图，可以选择何种价格级别（低价、高价、开盘、收盘）来启用FinancialSeriesViewBase.ReductionOptions，即在指定的价格低于前面的点的值的情况下，后续点被标记为红色（或其他任何一种颜色）
A Candle Stick chart is shown in the image below. Note that this chart type is based uponXYDiagram, so it can be rotated to show bars either vertically or horizontally.
继承自XYDiagram，所以工具条既可以垂直也可以水平显示。

| Full-Stacked Area Chart | |
5、全堆积面积图
The Full-Stacked Area Chart (100% Stacked Area Chart) is represented by theFullStackedAreaSeriesView object, which belongs to Area Series Views. This view displays series as areas on a diagram, so that the value of each data point is stacked with all the other corresponding data points' values. In this instance, the height of the area is always the full height of the chart diagram (i.e. 1). This view is useful for comparing the percentage values of several series for the same point arguments.
全堆积面积图表示FullStackedAreaSeriesView对象，属于面积序列视图集。这种视图在同一个图解（图示）中以面积区域显示序列，因此每一个数据点的值被所有其他相关数据点的值堆满了。在这种情况下，区域的高度通常是图表图解的全部高度（示例1）.这在比较相同输入参数（自变量）的几种百分比值输出时非常有用。
A Full-Stacked Area chart is shown in the image below. Note that this chart type is based upon theXYDiagram, so it can be rotated to show bars either vertically or horizontally.
图表类型：XYDiagram，所以可以旋转工具条到水平或垂直位置。
| Note |
|---|
|
A Full-Stacked Area chart can display series containing data points with positive or negative values. However, a series with positive values is stacked only with other series containing positive values; and a series with negative values is stacked with other series containing negative values. 全覆盖面积图表可以显示正值，也可以显示包含负值数据点的序列。但是，包含正值的序列仅能和其他包含正值的序列一起堆积，包含负值的序列仅能和包含负值的序列一起堆积。 Note that if a series contains data points with both positive and negative values, it is treated as a series with positive values, while all its negative values are treated as zeros. 如果一个序列既包含正数也包含负数的值，将被看做是正数序列，序列中的所有负值被当做零值。

The following example demonstrates how to create a ChartControl with two series of the FullStackedBarSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.
Then, add the following code to the Form.Load event handler.
| C# |
using DevExpress.XtraCharts;
// ...
private void Form1_Load(object sender, EventArgs e) {
// Create a new chart.
ChartControl FullStackedBarChart = new ChartControl();
// Create two full-stacked bar series.
Series series1 = new Series("Series 1", ViewType.FullStackedBar);
Series series2 = new Series("Series 2", ViewType.FullStackedBar);
// Add points to them.
series1.Points.Add(new SeriesPoint(1, 10));
series1.Points.Add(new SeriesPoint(2, 12));
series1.Points.Add(new SeriesPoint(3, 14));
series1.Points.Add(new SeriesPoint(4, 17));
series2.Points.Add(new SeriesPoint(1, 15));
series2.Points.Add(new SeriesPoint(2, 18));
series2.Points.Add(new SeriesPoint(3, 25));
series2.Points.Add(new SeriesPoint(4, 33));
// Add both series to the chart.
FullStackedBarChart.Series.AddRange(new Series[] { series1, series2 });
// Set the numerical argument scale types for the series,
// as it is qualitative, by default.
series1.ArgumentScaleType = ScaleType.Numerical;
series2.ArgumentScaleType = ScaleType.Numerical;
// Access the view-type-specific options of the series.
((FullStackedBarSeriesView)series1.View).BarWidth = 0.4;
// Access the type-specific options of the diagram.
((XYDiagram)FullStackedBarChart.Diagram).EnableAxisXZooming = true;
// Hide the legend (if necessary).
FullStackedBarChart.Legend.Visible = false;
// Add the chart to the form.
FullStackedBarChart.Dock = DockStyle.Fill;
this.Controls.Add(FullStackedBarChart);

7、全堆折线图
The Full-Stacked Line Chart (100%-Stacked Line Chart) is represented by the FullStackedLineSeriesView object, which belongs to Point, Line and Spline Series Views. This chart is useful when it is necessary to compare how much each series adds to the total aggregate value for specific arguments.
对于指定参数，全堆叠折线图用来比较每一个序列添加到合计值中的比例。比如对于USA，Hydro-electric（水力发电）占3%，Oil石油站40,%，总共占能源中的43%，Natural gas（天然气）占25%，三种能源一起占总能源的68%。
全堆折线图用FullStackedLineSeriesView对象表示，属于点，线和样条序列视图集Point, Line and Spline Series Views.在比较
A Full-Stacked Line chart is shown in the image below. Note that this chart type is based upon XYDiagram, and so it can be rotated to show lines either vertically or horizontally.
| Note |
|---|
|
A Full-Stacked Line chart can display series containing data points with positive or negative values. However, a series with positive values is stacked only with other series containing positive values; and a series with negative values is stacked with other series containing negative values. Note that if a series contains data points with both positive and negative values, it is treated as a series with positive values, while all its negative values are treated as zeros.
|
The table below lists the main characteristics of this chart type.
|
Feature |
Value |
|---|---|
| Series View type | FullStackedLineSeriesView |
| Diagram type | 2D-XYDiagram |
| Number of arguments per series point | 1 |
| Number of values per series point | 1 |

8、全堆积样条面积图表
The Full-Stacked Spline Area Chart (100% Stacked Spline Area Chart) is represented by the FullStackedSplineAreaSeriesView object, which belongs to Area Series Views. This view is similar to Full-Stacked Area Chart, but plots a fitted curve through each data point in a series.
全堆积样条面积图表用FullStackedSplineAreaSeriesView对象表示，属于面积序列视图集，与全堆积面积图表类似，但是绘制一个通过各序列点的拟合曲线。

The following example demonstrates how to create a ChartControl with a series of the FullStackedSplineAreaSeriesView type, set its general properties, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.
Then, add the following code to the Form.Load event handler.
| C# |
using System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...
private void Form1_Load(object sender, EventArgs e) {
// Create an empty chart.
ChartControl fullStackedSplineAreaChart = new ChartControl();
// Create two series of the FullStackedSplineArea view type.
Series series1 = new Series("Series 1", ViewType.FullStackedSplineArea);
Series series2 = new Series("Series 2", ViewType.FullStackedSplineArea);
// Populate both series with points.
series1.Points.Add(new SeriesPoint("A", 80));
series1.Points.Add(new SeriesPoint("B", 20));
series1.Points.Add(new SeriesPoint("C", 50));
series1.Points.Add(new SeriesPoint("D", 30));
series2.Points.Add(new SeriesPoint("A", 40));
series2.Points.Add(new SeriesPoint("B", 60));
series2.Points.Add(new SeriesPoint("C", 20));
series2.Points.Add(new SeriesPoint("D", 80));
// Add the series to the chart.
fullStackedSplineAreaChart.Series.AddRange(new Series[] {
series1,
series2});
// Adjust the view-type-specific options of the series.
((FullStackedSplineAreaSeriesView)series1.View).LineTensionPercent = 80;
((FullStackedSplineAreaSeriesView)series2.View).Transparency = 80;
// Access the diagram's options.
((XYDiagram)fullStackedSplineAreaChart.Diagram).Rotated = true;
// Add a title to the chart and hide the legend.
ChartTitle chartTitle1 = new ChartTitle();
chartTitle1.Text = "Full Stacked Spline Area Chart";
fullStackedSplineAreaChart.Titles.Add(chartTitle1);
fullStackedSplineAreaChart.Legend.Visible = false;
// Add the chart to the form.
fullStackedSplineAreaChart.Dock = DockStyle.Fill;
this.Controls.Add(fullStackedSplineAreaChart);
}
