Cara Mengatur Properti Sumbu Bagan

Jika Anda ingin bekerja dengan sumbu bagan, penskalaan, dan unit tampilan untuk sumbu nilai, gunakan kelas ChartAxis, AxisDisplayUnit, dan AxisScaling.

Contoh kode berikut menunjukkan cara menentukan properti sumbu X dan 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);

Cara Menyelaraskan Label Bagan

Jika Anda ingin menyetel perataan teks untuk label multi-baris, Anda cukup melakukannya dengan menyetel nilai properti TickLabelAlignment. Contoh kode berikut menunjukkan cara mencentang perataan label.

	For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C

	System::SharedPtr<ChartAxis> axis = shape->get_Chart()->get_AxisX();

	//This property has effect only for multi-line labels.
	axis->set_TickLabelAlignment(ParagraphAlignment::Right);
