设置图表的图例

使用 Aspose.Cells for Python via .NET Legend 管理图表图例非常简单。

以下代码片段演示了如何管理图例:

from aspose.cells import Workbook
from aspose.cells.charts import ChartType, LegendPositionType
from aspose.pydrawing import Color

#  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 title of a chart
chart.title.text = "Title"
#  Setting the font color of the chart title to blue
chart.title.font.color = Color.blue
#  Move the legend to left
chart.legend.position = LegendPositionType.LEFT
#  Set font color of the legend
chart.legend.font.color = Color.blue
#  Save the file
workbook.save("chart_legend.xlsx")
