I'm trying to create a Bar Chart in an XLSX Spreadsheet using Apache POI, but Excel keeps saying that there's a problem with the content and deleting the chart when I try to open the file. Here's the full code of what I'm trying to do:
public static void createBarChart() {
Workbook wb = new XSSFWorkbook();
Sheet sheet = wb.createSheet("Sheet2");
Row row;
Cell cell;
row = sheet.createRow(0);
row.createCell(0);
row.createCell(1).setCellValue("HEADER 1");
row.createCell(2).setCellValue("HEADER 2");
row.createCell(3).setCellValue("HEADER 3");
for (int r = 1; r < 5; r++) {
row = sheet.createRow(r);
cell = row.createCell(0);
cell.setCellValue("Serie " + r);
cell = row.createCell(1);
cell.setCellValue(123);
cell = row.createCell(2);
cell.setCellValue(456);
cell = row.createCell(3);
cell.setCellValue(789);
}
Drawing drawing = sheet.createDrawingPatriarch();
ClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 0, 5, 5, 20);
Chart chart = drawing.createChart(anchor);
CTChart ctChart = ((XSSFChart) chart).getCTChart();
ctChart.addNewTitle();
CTPlotArea ctPlotArea = ctChart.getPlotArea();
CTBarChart ctBarChart = ctPlotArea.addNewBarChart();
ctBarChart.addNewBarDir().setVal(STBarDir.COL);
ctBarChart.addNewGrouping().setVal(STBarGrouping.CLUSTERED);
ctBarChart.addNewVaryColors().setVal(false);
// First series
CTBarSer ctBarSer = ctBarChart.addNewSer();
ctBarSer.addNewIdx().setVal(0);
ctBarSer.addNewOrder().setVal(0);
// [01] Title
CTSerTx ctSerTx = ctBarSer.addNewTx();
CTStrRef ctSerTxStrRef = ctSerTx.addNewStrRef();
ctSerTxStrRef.setF("Sheet2!$A$2");
CTStrData strCache = ctSerTxStrRef.addNewStrCache();
strCache.addNewPtCount().setVal(1);
CTStrVal newPt = strCache.addNewPt();
newPt.setV("Serie 1");
newPt.setIdx(0);
// [01] SpPr
CTShapeProperties spPr = ctBarSer.addNewSpPr();
CTSolidColorFillProperties solidFill = spPr.addNewSolidFill();
solidFill.addNewSchemeClr().setVal(STSchemeColorValImpl.ACCENT_1);
spPr.addNewLn().addNewNoFill();
spPr.addNewEffectLst();
// [01] Invert if negative
ctBarSer.addNewInvertIfNegative().setVal(false);
// [01] Series titles
CTAxDataSource newCat = ctBarSer.addNewCat();
CTStrRef addNewStrRef = newCat.addNewStrRef();
addNewStrRef.setF("Sheet2!$B$1:$D$1");
CTStrData addNewStrCache = addNewStrRef.addNewStrCache();
addNewStrCache.addNewPtCount().setVal(3);
CTStrVal pt1 = addNewStrCache.addNewPt();
pt1.setIdx(0);
pt1.setV(sheet.getRow(0).getCell(1).getStringCellValue());
CTStrVal pt2 = addNewStrCache.addNewPt();
pt2.setIdx(1);
pt2.setV(sheet.getRow(0).getCell(2).getStringCellValue());
CTStrVal pt3 = addNewStrCache.addNewPt();
pt3.setIdx(2);
pt3.setV(sheet.getRow(0).getCell(3).getStringCellValue());
// [01] Series values
CTNumDataSource newVal = ctBarSer.addNewVal();
CTNumRef numRef = newVal.addNewNumRef();
numRef.setF("Sheet2!$B$2:$D$2");
CTNumData numCache = numRef.addNewNumCache();
numCache.addNewPtCount().setVal(3);
CTNumVal numpt1 = numCache.addNewPt();
numpt1.setIdx(0);
numpt1.setV(String.valueOf(sheet.getRow(1).getCell(1).getNumericCellValue()));
CTNumVal numpt2 = numCache.addNewPt();
numpt2.setIdx(1);
numpt2.setV(String.valueOf(sheet.getRow(1).getCell(2).getNumericCellValue()));
CTNumVal numpt3 = numCache.addNewPt();
numpt3.setIdx(2);
numpt3.setV(String.valueOf(sheet.getRow(1).getCell(3).getNumericCellValue()));
// dLbls
CTDLbls dLbls = ctBarChart.addNewDLbls();
dLbls.addNewShowBubbleSize().setVal(false);
dLbls.addNewShowLegendKey().setVal(false);
dLbls.addNewShowCatName().setVal(false);
dLbls.addNewShowSerName().setVal(false);
dLbls.addNewShowPercent().setVal(false);
dLbls.addNewShowVal().setVal(false);
FileOutputStream fileOut = new FileOutputStream("barchart.xlsx");
wb.write(fileOut);
wb.close();
fileOut.close();
}
Can anyone help me find (and, well, solve) the issue? Thanks in advance!

Phew, difficult birth ;-). For users without knowledge of the background Apache POI supports only ScatterCharts and LineCharts why?. There is described how to proceed in principle.
As I said. Take the simplest possible bar chart for testing first. That is one series with two values. Then you would have seen that you have completely forgotten the axes in your code. A pie chart has no axes. Thats why there they are not necessary. But a bar chart will not work without axes.
Instead you can unscrupulously forget all things what is named "cache".
Whether other things are needed is determined by try and error. Also one could read the Office OpenXML recommendation. Probably the missing of all elements having minOccurs <> "0"` leads to deleting the Drawing while opening the Workbook.

This example needs the full jar of all of the schemas ooxml-schemas-1.3.jar as mentioned in the FAQ-N10025.
Above code has worked until apache poi 3.17.
Following code works using apache poi 4.1.0. It needs the full jar of all of the schemas ooxml-schemas-1.4.jar.
