管理Excel图表的轴

在Excel图表中，有3种类型的轴：

1. 水平（类别）轴：X轴
2. 垂直（值）轴：Y轴
3. 深度（系列）轴：Z轴

轴选项

Aspose.Cells for Python via .NET还允许在运行时管理图表的坐标轴，使用Axis对象，你可以像在Excel中一样更改Axis的所有选项。

管理X和Y轴

在Excel图表中，水平和垂直轴是最常用的两种轴。

以下代码片段演示了如何设置X和Y轴的选项。

from aspose.cells import Workbook
from aspose.cells.charts import ChartType

#  Instantiating a Workbook object
workbook = Workbook()
#  Adding a new worksheet to the Workbook object
sheetIndex = workbook.worksheets.add()
#  Obtaining the reference of the newly added worksheet by passing its sheet index
worksheet = workbook.worksheets[sheetIndex]
#  Adding sample values to cells
worksheet.cells.get("A1").put_value("Series1")
worksheet.cells.get("A2").put_value(50)
worksheet.cells.get("A3").put_value(100)
worksheet.cells.get("A4").put_value(150)
worksheet.cells.get("B1").put_value("Series2")
worksheet.cells.get("B2").put_value(60)
worksheet.cells.get("B3").put_value(32)
worksheet.cells.get("B4").put_value(50)
#  Adding a chart to the worksheet
chartIndex = worksheet.charts.add(ChartType.COLUMN, 5, 0, 15, 5)
#  Accessing the instance of the newly added chart
chart = worksheet.charts[chartIndex]
#  Adding SeriesCollection (chart data source) to the chart ranging from "A1" cell to "B3"
chart.set_chart_data_range("A1:B4", True)
# hiding X axis
chart.category_axis.is_visible = False
#  Setting max value of Y axis.
chart.value_axis.max_value = 200
#  Setting major unit.
chart.value_axis.major_unit = 50.0
#  Save the file
workbook.save("chart_axes.xlsx")
