How modify the Q3DBars with multiple color bars?

[f.lerdino]

I want to modify the "bars" in the QT example because I need that the bars are set with differents colors.
Any idea How to do that?

@f-lerdino
Is that what you mean?
I also want to know how this is achieved.

@f-lerdino if you want something like this:

there is code:

QGuiApplication app (argc, argv);

	Q3DBars bars;
	bars.resize (800, 800);

	// Remove the frame for a borderless window
	bars.setFlags (bars.flags () ^ Qt::FramelessWindowHint);

	bars.rowAxis ()->setRange (0, 4);
	bars.columnAxis ()->setRange (0, 4);

	QBar3DSeries* series = new QBar3DSeries;

	// Set the color style for the series to ColorStyleRangeGradient
	series->setColorStyle (Q3DTheme::ColorStyleRangeGradient);

	// Define colors for the color style range gradient
	QLinearGradient gradient;
	gradient.setColorAt (0.0, Qt::green);
	gradient.setColorAt (0.5, Qt::yellow);
	gradient.setColorAt (1.0, Qt::red);

	// Create a data proxy for the series
	QBarDataProxy* dataProxy = new QBarDataProxy;

	// Create data items with values
	QBarDataRow* dataRow = new QBarDataRow;
	for (int i = 0; i < 5; ++i) {
		dataRow->append (QBarDataItem (1.0f * 0.1 * i));
	}

	// Assign color style range gradient to the data proxy
	//dataProxy->setColorStyle (gradient);

	// Add data row to the data proxy
	dataProxy->addRow (dataRow);

	// Set data proxy for the series
	series->setDataProxy (dataProxy);
	series->setBaseGradient (gradient);
	bars.addSeries (series);
	bars.show ();

	return app.exec ();
}

the key is "series->setColorStyle (Q3DTheme::ColorStyleRangeGradient);"
