管理Excel图表的标题

在Excel图表中，有两种标题：

1. 图表标题
2. 轴标题

标题选项

Aspose.Cells for Python via .NET 还允许在运行时管理图表的标题，借助 Title 对象，可以更改标题的文本、字体和填充格式。

设置图表或坐标轴的标题

你可以使用 Microsoft Excel 在可视化环境中设置图表及其轴的标题。Aspose.Cells for Python via .NET 也允许开发者在运行时设置图表和轴的标题。所有图表及其轴都包含一个 标题 属性，可以用来设置它们的标题，如下面的示例所示。

以下代码段演示了如何设置图表和轴的标题。

from aspose.cells import Workbook
from aspose.cells.charts import ChartType
from aspose.cells.drawing import GradientStyleType
from aspose.pydrawing import Color
from os import os, path

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Create directory if it is not already present.
IsExists = path.isdir(dataDir)
if notIsExists:
    os.makedirs(dataDir)
#  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(50)
worksheet.cells.get("A2").put_value(100)
worksheet.cells.get("A3").put_value(150)
worksheet.cells.get("B1").put_value(60)
worksheet.cells.get("B2").put_value(32)
worksheet.cells.get("B3").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.n_series.add("A1:B3", True)
#  Setting the foreground color of the plot area
chart.plot_area.area.foreground_color = Color.blue
#  Setting the foreground color of the chart area
chart.chart_area.area.foreground_color = Color.yellow
#  Setting the foreground color of the 1st SeriesCollection area
chart.n_series[0].area.foreground_color = Color.red
#  Setting the foreground color of the area of the 1st SeriesCollection point
chart.n_series[0].points[0].area.foreground_color = Color.cyan
#  Filling the area of the 2nd SeriesCollection with a gradient
chart.n_series[1].area.fill_format.set_one_color_gradient(Color.lime, 1, GradientStyleType.HORIZONTAL, 1)
#  Setting the title of a chart
chart.title.text = "Title"
#  Setting the font color of the chart title to blue
chart.title.font.color = Color.blue
#  Setting the title of category axis of the chart
chart.category_axis.title.text = "Category"
#  Setting the title of value axis of the chart
chart.value_axis.title.text = "Value"
#  Saving the Excel file
workbook.save(dataDir + "book1.out.xls")
