Color BarChart bars depending on data using Apache POI

I'm trying to set the fill color of each individual bar of my chart to a separate custom color but I have yet to discover how.
Here's my code so far. The layout is fine but the chart bars are all the same color (cornflower blue). I'm aware that I can use the XDDFChartData:setVaryColors option to use different colors but I can't find a way to specify which colors to use (say in my example 'Books' in red, 'DVDs' in blue, etc.).
final Workbook workbook = new XSSFWorkbook();
final Sheet sheet = workbook.createSheet("MySheet");
Row row = sheet.createRow(1);
Cell cell = row.createCell(1);
cell.setCellValue("Product");
cell = row.createCell(2);
cell.setCellValue("Orders");
row = sheet.createRow(2);
cell = row.createCell(1);
cell.setCellValue("Books");
cell = row.createCell(2);
cell.setCellValue(50);
row = sheet.createRow(3);
cell = row.createCell(1);
cell.setCellValue("DVDs");
cell = row.createCell(2);
cell.setCellValue(25);
row = sheet.createRow(4);
cell = row.createCell(1);
cell.setCellValue("CDs");
cell = row.createCell(2);
cell.setCellValue(140);
XSSFDrawing drawing = ((XSSFSheet) sheet).createDrawingPatriarch();
XSSFClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 4, 1, 12, 15 );
XSSFChart chart = drawing.createChart(anchor);
chart.setTitleText("Products");
chart.setTitleOverlay(false);
CTBoolean FALSE = CTBoolean.Factory.newInstance();
FALSE.setVal(false);
chart.getCTChartSpace().setRoundedCorners(FALSE);
XDDFCategoryAxis bottomAxis = chart.createCategoryAxis(AxisPosition.BOTTOM);
bottomAxis.setMajorTickMark(AxisTickMark.NONE);
XDDFValueAxis leftAxis = chart.createValueAxis(AxisPosition.LEFT);
leftAxis.setCrosses(AxisCrosses.AUTO_ZERO);
leftAxis.setCrossBetween(AxisCrossBetween.BETWEEN);
XDDFDataSource<String> compliances = XDDFDataSourcesFactory.fromStringCellRange((XSSFSheet) sheet, new CellRangeAddress(2, 4, 1, 1));
XDDFNumericalDataSource<Double> components = XDDFDataSourcesFactory.fromNumericCellRange((XSSFSheet) sheet, new CellRangeAddress(2, 4, 2, 2));
XDDFChartData data = chart.createData(ChartTypes.BAR, bottomAxis, leftAxis);
XDDFChartData.Series series1 = data.addSeries(compliances, components);
series1.setTitle("Components by Compliance", null);
chart.plot(data);
XDDFBarChartData bar = (XDDFBarChartData) data;
bar.setBarDirection(BarDirection.BAR);
CTSRgbColor rgb = CTSRgbColor.Factory.newInstance();
Color col1 = new Color(100, 149, 237);
rgb.setVal(new byte[]{(byte) col1.getRed(), (byte) col1.getGreen(), (byte) col1.getBlue()});
CTSolidColorFillProperties fillProp = CTSolidColorFillProperties.Factory.newInstance();
fillProp.setSrgbClr(rgb);
CTShapeProperties ctShapeProperties = CTShapeProperties.Factory.newInstance();
ctShapeProperties.setSolidFill(fillProp);
chart.getCTChart().getPlotArea().getBarChartList().get(0).getSerList().get(0).setSpPr(ctShapeProperties);
IntStream.range(0, 10).forEach(sheet::autoSizeColumn);
Any ideas?
Cheers!

It seems as if you wants coloring each data point instead of the bar series. If so then this is the same problem as with how to set custom colors in pie 3D Chart using Apache poi 4.1.2. Difference is only the chart type.
There is no XDDF method to set data point colors until now. Only series colors can be set using XDDF methods. So one must use the underlying org.openxmlformats.schemas.drawingml.x2006.chart.* classes. Following complete example shows this. It sets data point colors from a bunch of formerly set rgb byte arrays.

Apache POI Chart Axis endarrow

I'm trying to get a different ending from a line chart witch apache Poi.
This is my Code. It's creates an this Chart without the arrow.
I couldn't find a Axis "Style Class" or something like this.
XSSFDrawing drawing = sheet.createDrawingPatriarch();
XSSFClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 0, 5, 10, 15);
XSSFChart chart = drawing.createChart(anchor);
setRoundedCorners(chart, false);
XDDFChartLegend legend = chart.getOrAddLegend();
legend.setPosition(LegendPosition.TOP_RIGHT);
// Use a category axis for the bottom axis.
XDDFCategoryAxis bottomAxis = chart.createCategoryAxis(AxisPosition.BOTTOM);
bottomAxis.setTitle("x"); // https://stackoverflow.com/questions/32010765
//XDDFValueAxis valueAxis = chart.createValueAxis(AxisPosition.BOTTOM);
//bottomAxis.setMajorTickMark(AxisTickMark.CROSS);
XDDFValueAxis leftAxis = chart.createValueAxis(AxisPosition.LEFT);
leftAxis.setTitle("f(x)");
leftAxis.setCrosses(AxisCrosses.AUTO_ZERO);
I added the arrow after the creation. Does anyone now how I can create the arrow inside the Code?
I changed the Axis class to XDDFValueAxis and found something that looks like my mussing feature but unfortunately throw the line 'lineProperties.getHeadEnd()' an null pointer exception.
XDDFValueAxis valueAxis = chart.createValueAxis(AxisPosition.BOTTOM);
XDDFShapeProperties shapeProperties = valueAxis.getOrAddShapeProperties();
XDDFLineProperties lineProperties = shapeProperties.getLineProperties();
XDDFLineEndProperties lineEndProperties = lineProperties.getHeadEnd();
lineEndProperties.setType(LineEndType.ARROW);
valueAxis.setTitle("x");
How can I create XDDFLineEndProperties the constructor is protected?
Here is the full Code Example if needed.

You could have a public class which extends XDDFLineEndProperties and provides a not protected constructor:
import org.apache.poi.xddf.usermodel.XDDFLineEndProperties;
import org.openxmlformats.schemas.drawingml.x2006.main.CTLineEndProperties;
public class MyXDDFLineEndProperties extends XDDFLineEndProperties {
public MyXDDFLineEndProperties() {
super(CTLineEndProperties.Factory.newInstance());
}
}
Then you could use that like this:
...
// Use a category axis for the bottom axis.
XDDFCategoryAxis bottomAxis = chart.createCategoryAxis(AxisPosition.BOTTOM);
bottomAxis.setTitle("x"); // https://stackoverflow.com/questions/32010765
XDDFShapeProperties shapeProperties = bottomAxis.getOrAddShapeProperties();
XDDFLineProperties lineProperties = new XDDFLineProperties();
MyXDDFLineEndProperties lineEndProperties = new MyXDDFLineEndProperties();
lineEndProperties.setType(LineEndType.ARROW);
lineProperties.setTailEnd(lineEndProperties);
shapeProperties.setLineProperties(lineProperties);
...

Excel Generation [Java] - BarChart - Enable Multi Category Label

I have excel generation using org.apache.poi library. Here i need to generate a bar chart which should show like below:
And my excel look like:
Code:
//CellRangeAddress(int firstRow, int lastRow, int firstCol, int lastCol)
XDDFDataSource<String> department = XDDFDataSourcesFactory.fromStringCellRange(sheet,
new CellRangeAddress(7, 17, 1, 1));
If i set CellRangeAddress firstCol - 0 and lastCol - 1 its not working?
Is any option to enable this in java:

Multi-level category labels are not possible using the XDDF stuff of apache poi. The XDDF always uses StrRef as references for chart data sources. To create multi-level category labels MultiLvlStrRef would must be used. So the task only is solvable using the low level org.openxmlformats.schemas.drawingml.x2006.chart.* classes directly.
That's why following code needs the full jar of all of the ooxml-schemas, which is ooxml-schemas-1.4.jar for current apache poi 4.1.2, in class path. The poi-ooxml-schemas-4.1.2.jar does not contain org.openxmlformats.schemas.drawingml.x2006.chart.CTMultiLvlStrRef.
And because of the crude logic of Microsoft, which uses a setting NoMultiLvlLbl-true as the default for category axes, one now must tell the category axis that it not has no multi level labels. So, if the axis shall have multi-level category labels, NoMultiLvlLbl must be set false. Well, seems that Microsoft wants to check whether programmers have learned their logic lessons well ;-).

how to generate piechart using apache poi 4.0 XDDFChartData, XDDFPieChartData; in excel sheet using java, i dont want to use jfree

I need a sample code in Java, currently I am able to draw line charts after reading values from sheet, and I also want to generate pie chart.
Example code I have tried which is for .ppt format.
I want the same in excel for pie chart in java.
String[] categories = listCategories.toArray(new String[listCategories.size()]);
Double[] values = listValues.toArray(new Double[listValues.size()]);
final int numOfPoints = categories.length;
final String categoryDataRange = chart.formatRange(new CellRangeAddress(1, numOfPoints, 0, 0));
final String valuesDataRange = chart.formatRange(new CellRangeAddress(1, numOfPoints, 1, 1));
final XDDFDataSource<?> categoriesData = XDDFDataSourcesFactory.fromArray(categories, categoryDataRange);
final XDDFNumericalDataSource<? extends Number> valuesData = XDDFDataSourcesFactory.fromArray(values, valuesDataRange);
XDDFPieChartData.Series firstSeries = (XDDFPieChartData.Series) pie.getSeries().get(0);
firstSeries.replaceData(categoriesData, valuesData);
firstSeries.setTitle(chartTitle, chart.setSheetTitle(chartTitle, 0));
firstSeries.setExplosion(25);
chart.plot(pie);

XDDFNumericalDataSource<Double> val = XDDFDataSourcesFactory.fromNumericCellRange(sheet,
new CellRangeAddress(1, 1, 0, NUM_OF_COLUMNS - 1));
XDDFChartData data = new XDDFPieChartData(chart.getCTChart().getPlotArea().addNewPieChart());
data.setVaryColors(true);
data.addSeries(cat, val);
chart.plot(data);
// Write the output to a file
try (FileOutputStream fileOut = new FileOutputStream("ooxml-pie-chart.xlsx")) {
wb.write(fileOut);
}
}
}
}
The above is the minimal example using only the XDDF stuff. Here is a more extended version which sets data labels and makes the chart visible in LibreOffice/OpenOffice Calc. But this needs using the low level org.openxmlformats.schemas.drawingml.x2006.chart.* stuff.

Since version apache poi 4.1.1 creation of the XDDFChartData data must be changed like:
...
import org.apache.poi.xddf.usermodel.chart.ChartTypes;
...
//XDDFChartData data = new XDDFPieChartData(chart.getCTChart().getPlotArea().addNewPieChart());
XDDFChartData data = chart.createData(ChartTypes.PIE, null, null);
...

Also, as this answer is what shows google, I would like to add that the options mentioned at org.openxmlformats.schemas.drawingml.x2006.chart.STDLblPos.OUT_END maps to the options available at "Format Data Labels" in excel (or see https://www.youtube.com/watch?v=y85DOG5FOVc). To open that, right click on the chart to show that menu option. That is useful if you want to hide some data. By default show almost everything. For example, to show only the value data:
dLbls.addNewDLblPos().setVal(org.openxmlformats.schemas.drawingml.x2006.chart.STDLblPos.BEST_FIT);
dLbls.addNewShowLegendKey().setVal(false);
dLbls.addNewShowPercent().setVal(false);
dLbls.addNewShowCatName().setVal(false);
dLbls.addNewShowSerName().setVal(false);
dLbls.addNewShowVal().setVal(true);
dLbls.addNewShowLeaderLines().setVal(false);

ScatterChart using LineMarker as ScatterStyle instead of only Marker

After building a XSSFScatterChartData and I filling it using the method XSSFChart.plot(ChartData data, ChartAxis... chartAxis), the plot contains markers but linked by a line..
I think the problem comes from the method XSSFScatterChartData.addStyle which sets a STScatterStyle.LINE_MARKER by default.
Here is a copy of the method I use to generate the chart:
private void setTrainingTimeGraph(Sheet trainingTimeSheet, Sheet resultsSheet) {
Drawing drawing = trainingTimeSheet.createDrawingPatriarch();
ClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 5, 5, 20, 30);
XSSFChart chart = (XSSFChart) drawing.createChart(anchor);
ChartLegend legend = chart.getOrCreateLegend();
legend.setPosition(LegendPosition.TOP_RIGHT);
chart.setTitleText("Training time over Fscore");
XSSFScatterChartData data = chart.getChartDataFactory().createScatterChartData();
ValueAxis bottomAxis = chart.getChartAxisFactory().createValueAxis(AxisPosition.BOTTOM);
ValueAxis leftAxis = chart.getChartAxisFactory().createValueAxis(AxisPosition.LEFT);
setValueAxisTitle((XSSFChart) chart,0,"Fscore");
setValueAxisTitle((XSSFChart) chart,1, "Training Time");
leftAxis.setCrosses(AxisCrosses.AUTO_ZERO);
bottomAxis.setCrosses(AxisCrosses.AUTO_ZERO);
ChartDataSource<Number> xs = DataSources.fromNumericCellRange(resultsSheet, new CellRangeAddress(16, 29, 10, 10));
ChartDataSource<Number> ys = DataSources.fromNumericCellRange(resultsSheet, new CellRangeAddress(16, 29, 18, 18));
data.addSerie(xs, ys);
chart.plot(data,bottomAxis, leftAxis);
}
UPDATE
So adding #AxelRichter code to set to no fill in my scatter chart data serie:
...
data.addSerie(xs, ys);
chart.plot(data,bottomAxis, leftAxis);
//set line properties of first scatter chart data serie to no fill:
((XSSFChart)chart).getCTChart().getPlotArea().getScatterChartArray(0).getSerArray(0)
.addNewSpPr().addNewLn().addNewNoFill();
I manged to get rid of the lines linking the Markers.. Finally!
But the second part wasn't what I was looking for. Let me explain it a little bit better:
When I pass hover each point in my scatterPlot there is some text which pops up ("label/x_value", x_value,y_value). The value in the legend is the same as its "label/x_value". I would like to set for each data point and for each value in legend its "label/x_value".
Thanks in advance!

Excel scatter charts will always have line between the markers too. If you don't wants to see this line it's fill color must be set to no fill.
References:
CTScatterSer -> CTShapeProperties -> CTLineProperties -> CTLineProperties.addNewNoFill
And for having data labels the series needs a CTDLbl setting.

This code needs the full jar of all of the schemas ooxml-schemas-1.3.jar as mentioned in FAQ-N10025.
This code works using the current last stable release apache poi version 3.17. Note: The Chart code of apache poi is highly in development now. So the code may not work in further releases.

So basing myself on the anwser of #Axel Richter.
Here is the to code used as basis:

final int NUM_OF_ROWS = 2;

Row row;
Cell cell;
//x values
for (int rowIndex = 0; rowIndex < 1; rowIndex++) {
row = sheet.createRow((short) rowIndex);
for (int colIndex = 0; colIndex < NUM_OF_COLUMNS; colIndex++) {

cell.setCellValue(4*colIndex * (rowIndex + 1));
}
}
// y values
for (int rowIndex = 1; rowIndex < NUM_OF_ROWS; rowIndex++) {
row = sheet.createRow((short) rowIndex);
for (int colIndex = 0; colIndex < NUM_OF_COLUMNS; colIndex++) {
cell = row.createCell((short) colIndex);
cell.setCellValue(Math.sin(Math.PI*colIndex/10*2));
}
}
Drawing<?> drawing = sheet.createDrawingPatriarch();
ClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 0, 3, 13, 20);
Chart chart = drawing.createChart(anchor);
ChartLegend legend = chart.getOrCreateLegend();
legend.setPosition(LegendPosition.TOP_RIGHT);
ScatterChartData data = chart.getChartDataFactory().createScatterChartData();
ValueAxis bottomAxis = chart.getChartAxisFactory().createValueAxis(AxisPosition.BOTTOM);
ValueAxis leftAxis = chart.getChartAxisFactory().createValueAxis(AxisPosition.LEFT);
leftAxis.setCrosses(AxisCrosses.AUTO_ZERO);
bottomAxis.setCrosses(AxisCrosses.AUTO_ZERO);
for (int i = 0; i < NUM_OF_COLUMNS; i++) {
ChartDataSource<Number> xs = DataSources.fromNumericCellRange(sheet, new CellRangeAddress(0, 0, i, i));
ChartDataSource<Number> ys = DataSources.fromNumericCellRange(sheet, new CellRangeAddress(1, 1, i, i));
ScatterChartSeries chartSerie = data.addSerie(xs, ys);
chartSerie.setTitle("My Title " + i);
}
chart.plot(data, bottomAxis, leftAxis);
//set line properties of first scatter chart data serie to no fill:
CTScatterSer[] scatterChartSeries = ((XSSFChart) chart).getCTChart().getPlotArea().getScatterChartArray(0).getSerArray();
for (int i = 0; i < scatterChartSeries.length; i++) {
scatterChartSeries[i].addNewSpPr().addNewLn().addNewNoFill();
}
wb.write(new FileOutputStream("CreateExcelScatterChart.xlsx"));
wb.close();
}
}
It will generate 20 series each one with a title when passing hover and the same title in the legend. There will be as no lines between each marker. So basically it does what I was looking for.
Thank you for your answers.
Ps: In case that you want to use some labels on each marker follow the //set data labels for first scatter chart data serie on #Richet answer
