怎么更改生成的折线图的线的颜色？

[AlexNosk]

@wangchunle 您可以使用Stroke.Color设置折线图中线条的颜色。 例如看下面的代码：

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Add chart with default data. You can specify different chart types and sizes.
Shape shape = builder.insertChart(ChartType.LINE, 432, 252);

// Chart property of Shape contains all chart related options.
Chart chart = shape.getChart();

// Get chart series collection.
ChartSeriesCollection seriesColl = chart.getSeries();

// Delete default generated series.
seriesColl.clear();

// Create category names array, in this example we have two categories.
String[] categories = new String[] { "AW Category 1", "AW Category 2" };

// Adding new series. Please note, data arrays must not be empty and arrays must be the same size.
ChartSeries s1 = seriesColl.add("AW Series 1", categories, new double[] { 1, 2 });
ChartSeries s2 = seriesColl.add("AW Series 2", categories, new double[] { 3, 4 });
ChartSeries s3 = seriesColl.add("AW Series 3", categories, new double[] { 5, 6 });
ChartSeries s4 = seriesColl.add("AW Series 4", categories, new double[] { 7, 8 });

// Set color of the lines
s1.getFormat().getStroke().setColor(Color.red);
s2.getFormat().getStroke().setColor(Color.black);
s3.getFormat().getStroke().setColor(Color.blue);
s4.getFormat().getStroke().setColor(Color.yellow);

doc.save("C:\\Temp\\out.docx");

@AlexNosk 谢谢，请问getFormat（）这个方法哪个版本才有？我现在项目里用的是19.5版本的，好像没有这个方法。
