如何创建组合图表

可能的使用场景

Excel中的组合图表让您能够利用此选项，因为您可以轻松地组合两种或更多种图表类型，以使您的数据易于理解。当您的数据包含多种值（包括价格和交易量）时，组合图表是有用的。此外，当您的数据数字在系列之间有明显变化时，组合图表是可行的。 以以下数据集为例，我们可以观察到这些数据与VHCL中提到的数据相当相似。如果我们希望将与“总收入”对应的series0可视化为线图表，应该如何操作？

组合图表

运行以下代码后，您将看到下面展示的组合图表。

示例代码

以下示例代码加载了示例Excel文件并生成了输出Excel文件。

from aspose.cells import Workbook
from aspose.cells.charts import ChartMarkerType, ChartType, FormattingType, LegendPositionType
from aspose.cells.drawing import LineType
from aspose.pydrawing import Color

#  Create the workbook
workbook = Workbook("combo.xlsx")
#  Access the first worksheet
worksheet = workbook.worksheets[0]
#  Add a stock vloume(VHLC)
pieIdx = worksheet.charts.add(ChartType.STOCK_VOLUME_HIGH_LOW_CLOSE, 15, 0, 34, 12)
#  Retrieve the Chart object
chart = worksheet.charts[pieIdx]
#  Set the legend can be showed
chart.show_legend = True
#  Set the chart title name
chart.title.text = "Combo Chart"
#  Set the Legend at the bottom of the chart area
chart.legend.position = LegendPositionType.BOTTOM
#  Set data range
chart.set_chart_data_range("A1:E12", True)
#  Set category data
chart.n_series.category_data = "A2:A12"
#  Set the Series[1] Series[2] and Series[3] to different Marker Style
