Python：使用图表创建Excel工作表

问题描述

是否有任何用于使用Python嵌入图表创建Excel图表的模块？ 中提到的模块似乎没有这种功能。

Is there any module for creating Excel charts with embedded charts in Python? The modules mentioned in this question don't seem to have that capability.

我更喜欢在Ubuntu下工作的通用模块，而不是依赖于Windows的。

I prefer a generic module that would work under Ubuntu, not a Windows-dependent one.

编辑： strong>我也会欣赏如何在创建的图表中嵌入图像，因为我可以在外部程序中创建图表并将其放在正确的表格中。

I will also appreciate ways to embed images within the created charts, as I can create the charts in an external program and place them within the right sheet.

谢谢，

Adam

推荐答案

这有点复杂（和/或邪恶），但是这样的东西将使用跨平台（包括在Linux下）来包装 Excel Java库。

It's a little bit convoluted (and/or evil), but something like this will work cross-platform (including under Linux) using JPype to wrap the SmartXLS Excel Java library.

此示例使用SmartXLS中的简单图表创建（以Charts / ChartSample.class为例）。

This example uses the simple chart creation (in Charts/ChartSample.class) example from SmartXLS.

#!/usr/bin/env python

import os
import os.path

import jpype

# or wherever your java is installed
os.environ['JAVA_HOME'] = "/usr/lib64/jvm/default-java"

root = os.path.abspath(os.path.dirname(__file__))

SX_JAR = os.path.join(root, 'SX.jar')

options = [
    '-Djava.class.path=%s' % SX_JAR
]

jpype.startJVM(jpype.getDefaultJVMPath(), *options)

WorkBook = jpype.JClass('com.smartxls.WorkBook')
ChartShape = jpype.JClass('com.smartxls.ChartShape')
ChartFormat = jpype.JClass('com.smartxls.ChartFormat')
Color = jpype.JClass('java.awt.Color')

workbook = WorkBook()

workbook.setText(0,1,"Jan")
workbook.setText(0,2,"Feb")
workbook.setText(0,3,"Mar")
workbook.setText(0,4,"Apr")
workbook.setText(0,5,"Jun")

workbook.setText(1,0,"Comfrey")
workbook.setText(2,0,"Bananas")
workbook.setText(3,0,"Papaya")
workbook.setText(4,0,"Mango")
workbook.setText(5,0,"Lilikoi")

for col in range(1, 5 + 1):
    for row in range(1, 5 + 1):
        workbook.setFormula(row, col, "RAND()")
workbook.setText(6, 0, "Total")
workbook.setFormula(6, 1, "SUM(B2:B6)")
workbook.setSelection("B7:F7")
# auto fill the range with the first cell's formula or data
workbook.editCopyRight()

left = 1.0
top = 7.0
right = 13.0
bottom = 31.0

# create chart with it's location
chart = workbook.addChart(left,top,right,bottom)
chart.setChartType(ChartShape.Column)
# link data source, link each series to columns(true to rows).
chart.setLinkRange("Sheet1!$a$1:$F$6", False)
# set axis title
chart.setAxisTitle(ChartShape.XAxis, 0, "X-axis data")
chart.setAxisTitle(ChartShape.YAxis, 0, "Y-axis data")
# set series name
chart.setSeriesName(0, "My Series number 1")
chart.setSeriesName(1, "My Series number 2")
chart.setSeriesName(2, "My Series number 3")
chart.setSeriesName(3, "My Series number 4")
chart.setSeriesName(4, "My Series number 5")
chart.setTitle("My Chart")

# set plot area's color to darkgray
chartFormat = chart.getPlotFormat()
chartFormat.setSolid()
chartFormat.setForeColor(Color.DARK_GRAY.getRGB())
chart.setPlotFormat(chartFormat)

# set series 0's color to blue
seriesformat = chart.getSeriesFormat(0)
seriesformat.setSolid()
seriesformat.setForeColor(Color.BLUE.getRGB())
chart.setSeriesFormat(0, seriesformat)

# set series 1's color to red
seriesformat = chart.getSeriesFormat(1)
seriesformat.setSolid()
seriesformat.setForeColor(Color.RED.getRGB())
chart.setSeriesFormat(1, seriesformat)

# set chart title's font property
titleformat = chart.getTitleFormat()
titleformat.setFontSize(14*20)
titleformat.setFontUnderline(True)
chart.setTitleFormat(titleformat)

workbook.write("./Chart.xls")

jpype.shutdownJVM()
