本教程说明了如何从CSV文件加载财务数据并使用LightningChart StockSeries显示它们。股票系列用于以烛台和股票条格式可视化股票交易数据。本教程假定您已在WinForms或WPF应用程序上使用LightningChart创建了新图表。如果没有，请按照我们的简单2D图表创建应用程序。

1.定义X轴和Y轴的变量，并将X轴配置为将值显示为日期。

// Configure X- and Y-axes.

// X-axis configuration.
var axisX = chart.ViewXY.XAxes[0];
axisX.Title.Text = "Date";
axisX.ValueType = AxisValueType.DateTime;
axisX.LabelsAngle = 90;
axisX.MajorDiv = 24 * 60 * 60; // Major division is one day in seconds.

// Y-axis configuration.
var axisY = chart.ViewXY.YAxes[0];
axisY.Title.Text = "Price";

// Create a new StockSeries.
var stockSeries = new StockSeries(chart.ViewXY, xAxis, yAxis);
chart.ViewXY.StockSeries.Add(stockSeries);

// Configure the stock plot.
stockSeries.Style = StockStyle.OptimizedCandleStick;
stockSeries.FillBorder.Width = 1;
stockSeries.Title.Text = "Example Inc.";

使用将数据从CSV文件加载到系列数据点中。数据必须按以下顺序按列组织：

series.LoadFromCSV(string fileName, SeparatorCSV separator)

stockSeries.LoadFromCSV("../../../data/data.csv", SeparatorCSV.Semicolon);

// Create a reference to the loaded data points.
var stockData = stockSeries.DataPoints;

// Generate data for series, which matches closed values.
var closeData = new SeriesPoint[stockData.Length];
for (var i = 0; i < stockData.Length; i++) { closeData[i] = new SeriesPoint() { X = xAxis.DateTimeToAxisValue(stockData[i].Date), Y = stockData[i].Close }; }

// Create a new PointLineSeries to show the dynamic in closed values on Stock Exchange.
var lineSeries = new PointLineSeries();
lineSeries.Title.Text = "Example Inc.";
lineSeries.Points = closeData;
chart.ViewXY.PointLineSeries.Add(lineSeries);

//Auto-scale X- and Y-axes.
chart.ViewXY.ZoomToFit();
