Cómo crear un gráfico de cascada

Contents
[ ]

La API de Aspose.Cells para Python via .NET permite crear un gráfico de cascada con la ayuda de un gráfico de líneas. La API también permite personalizar la apariencia del gráfico para darle forma de cascada configurando las propiedades Series.up_bars y Series.down_bars.

El fragmento de código a continuación demuestra el uso de la API Aspose.Cells para Python via .NET para crear un gráfico de cascada desde cero.

# Create an instance of Workbook
workbook = Workbook()
# Retrieve the first Worksheet in Workbook
worksheet = workbook.worksheets[0]
# Retrieve the Cells of the first Worksheet
cells = worksheet.cells
# Input some data which chart will use as source

cells.get("A2").put_value("January")
cells.get("A3").put_value("March")
cells.get("A4").put_value("August")

# Save the workbook
workbook.save(dataDir + "output_out.xlsx")
