Jak ustawić właściwości osi wykresu

Jeśli chcesz pracować z osiami wykresu, skalowaniem i jednostkami wyświetlania dla osi wartości, użyj klas ChartAxis, AxisDisplayUnit i AxisScaling.

Poniższy przykład kodu pokazuje, jak zdefiniować właściwości osi X i y:

	chart->get_Series()->Add(u"AW Series 1", dates, System::MakeArray<double>({640, 320, 280, 120, 150}));

	System::SharedPtr<ChartAxis> xAxis = chart->get_AxisX();
	System::SharedPtr<ChartAxis> yAxis = chart->get_AxisY();

	// Change the X axis to be category instead of date, so all the points will be put with equal interval on the X axis.
	xAxis->set_CategoryType(AxisCategoryType::Category);

	// Define X axis properties.
	xAxis->set_Crosses(AxisCrosses::Custom);
	xAxis->set_CrossesAt(3);
	// measured in display units of the Y axis (hundreds)
	xAxis->set_ReverseOrder(true);
	xAxis->set_MajorTickMark(AxisTickMark::Cross);
	xAxis->set_MinorTickMark(AxisTickMark::Outside);
	xAxis->set_TickLabelOffset(200);
