创建高低收（HLC）股票图表

可能的使用场景

高低收（HLC）股票图表使用四列数据。第一列通常是类别，通常是日期，但也可以使用股票名称。接下来的三列分别表示最高、最低和收盘价格。每个类别价格范围通过垂直线来表示，收盘价格则使用延伸至该线右侧的刻度线显示。

图表的可见性改进

有时，为了使图表看起来更直观，我们可以修改标记（收盘价）的外观，或者在辅助轴上显示它。

示例代码

以下示例代码加载示例Excel文件并生成输出Excel文件。

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

#  Create an instance of Workbook
workbook = Workbook("High-Low-Close.xlsx")
#  Access the first worksheet.
worksheet = workbook.worksheets[0]
# Create High-Low-Close-Stock Chart
pieIdx = worksheet.charts.add(ChartType.STOCK_HIGH_LOW_CLOSE, 5, 6, 20, 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 = "High-Low-Close Stock"
#  Set the Legend at the bottom of the chart area
chart.legend.position = LegendPositionType.BOTTOM
#  Set data range
chart.set_chart_data_range("A1:D9", True)
#  Set category data
chart.n_series.category_data = "A2:A9"
#  Set the marker with the built-in data
chart.n_series[2].marker.marker_style = ChartMarkerType.DASH
chart.n_series[2].marker.marker_size = 20
chart.n_series[2].marker.area.formatting = FormattingType.CUSTOM
chart.n_series[2].marker.area.foreground_color = Color.maroon
#  Fill the PlotArea area with nothing
chart.plot_area.area.fill_format.fill_type = FillType.NONE
#  Save the Excel file
workbook.save("out.xlsx")
