excel 使用 Apache poi 设计折线图
line chart design in excel using Apache poi
我正在创建一个包含折线图的 Excel 文件。我创建了图表并用数据填充了它,但我无法选择我想要的设计。如何使用 Apache poi 更改我的线条颜色、粗细和设计?
现在是白图:
我要的是黑色的那种:
这是我的代码
输入是这样的
people={100,200,150,140,130,120,110,100,90,85,80,75,70,65,60,55,50,45,40,35}

我已经更改了我的代码并且它工作得更好
并且我们可以定义颜色并可以使用系列更改所有内容。...
for example:
XDDFLineChartData.Series series1 = (XDDFLineChartData.Series) data.addSeries(countries, population);
color = "#0032FF";
lineSeriesColor(series1, XDDFColor.from(hex2Rgb(color)));
series1.setTitle("blue eye Population", null);
series1.setSmooth(true);
series1.setMarkerStyle(MarkerStyle.NONE);
series1.setMarkerStyle(...);
series1.setSmooth(..);
series1.getShapeProperties();
series1.setMarkerSize(...);
series1.setShapeProperties(...);
series1.getErrorBars();
series1.hasErrorBars();
series1.isSmooth();
series1.setTitle(...);
series1.plot();
...
public static void lineChart(int[] people, int[] blueEye) throws FileNotFoundException, IOException {
试试 (XSSFWorkbook wb = new XSSFWorkbook()) {
String sheetName = "EyeLineChart";
XSSFSheet sheet = wb.createSheet(sheetName);
Row row = sheet.createRow((short) 0);
Cell cell = row.createCell((short) 0);
cell.setCellValue("Year");

cell.setCellValue("people");
cell = row.createCell((short) 2);
cell.setCellValue("blue eye");
for (int i = 0; i < people.length; i++) {
row = sheet.createRow((short) i + 1);
cell = row.createCell((short) 0);
cell.setCellValue(i * 2000 / people.length);
cell = row.createCell((short) 1);
cell.setCellValue(people[i]);
cell = row.createCell((short) 2);
cell.setCellValue(blueEye[i]);
}
XSSFDrawing drawing = sheet.createDrawingPatriarch();
XSSFClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 3, 0, (people.length + 2000) / 100, 16);
XSSFChart chart = drawing.createChart(anchor);
chart.setTitleText("Population growth chart");
chart.setTitleOverlay(false);
XDDFChartLegend legend = chart.getOrAddLegend();

XDDFLineChartData data = (XDDFLineChartData) chart.createData(ChartTypes.LINE, bottomAxis, leftAxis);
XDDFLineChartData.Series series1 = (XDDFLineChartData.Series) data.addSeries(countries, area);
String color = "#DEDEDE";
lineSeriesColor(series1, XDDFColor.from(hex2Rgb(color)));
series1.setTitle("all of Population", null);
series1.setSmooth(true);
series1.setMarkerStyle(MarkerStyle.DIAMOND);
XDDFLineChartData.Series series2 = (XDDFLineChartData.Series) data.addSeries(countries, population);
color = "#0032FF";
lineSeriesColor(series2, XDDFColor.from(hex2Rgb(color)));
series2.setTitle("blue eye Population", null);
series2.setSmooth(true);
series2.setMarkerStyle(MarkerStyle.NONE);
chart.plot(data);
// Write output to an excel file
String filename = "chart.xlsx";
try (FileOutputStream fileOut = new FileOutputStream(filename)) {
wb.write(fileOut);
}
}
}
改变颜色应该使用:
private static void lineSeriesColor(XDDFChartData.Series series, XDDFColor color) {
XDDFSolidFillProperties fill = new XDDFSolidFillProperties(color);
XDDFLineProperties line = new XDDFLineProperties();
line.setFillProperties(fill);
XDDFShapeProperties properties = series.getShapeProperties();
if (properties == null) {
properties = new XDDFShapeProperties();
}
properties.setLineProperties(line);
series.setShapeProperties(properties);
}
并且有一个 hex
到 RGB
转换器以备不时之需:
private static byte[] hex2Rgb(String colorStr) {
int r = Integer.valueOf(colorStr.substring(1, 3), 16);
int g = Integer.valueOf(colorStr.substring(3, 5), 16);
int b = Integer.valueOf(colorStr.substring(5, 7), 16);
return new byte[]{(byte) r, (byte) g, (byte) b};
}
你给它 2 个数组,它给你一个图表
