Python:使用pycha快速绘制办公常用图(饼图、垂直直方图、水平直方图、散点图等七种图形)

一、代码：

[python] view
plaincopy

#!/usr/bin/env python

# -*- coding: utf-8 -*-

import cairo

import pycha.pie

import pycha.bar

import pycha.scatter

import pycha.stackedbar

import pycha.line

#设置画布

def set_charvalue():

width,height=600,600

surface=cairo.ImageSurface(cairo.FORMAT_ARGB32,width,height)

return surface

#画饼图

def draw_pie(surface, options, dataSet):

chart=pycha.pie.PieChart(surface,options)

chart.addDataset(dataSet)

chart.render()

surface.write_to_png('d:\\Pie.png')

#垂直直方图

def draw_vertical_bar(surface, options, dataSet):

chart=pycha.bar.VerticalBarChart(surface,options)

chart.addDataset(dataSet)

chart.render()

surface.write_to_png('d:\\vertical_bar.png')

#垂直水平直方图

def draw_horizontal_bar(surface, options, dataSet):

chart = pycha.bar.HorizontalBarChart(surface,options)

chart.addDataset(dataSet)

chart.render()

surface.write_to_png('d:\\horizontal_bar.png')

#线图

def draw_line(surface, options, dataSet):

chart = pycha.line.LineChart(surface,options)

chart.addDataset(dataSet)

chart.render()

surface.write_to_png('d:\\line.png')

#点图

def draw_scatterplot(surface, options, dataSet):

chart = pycha.scatter.ScatterplotChart(surface,options)

chart.addDataset(dataSet)

chart.render()

surface.write_to_png('d:\\scatterplotChart.png')

#垂直块图

def draw_stackedverticalbarChar(surface, options, dataSet):

chart = pycha.stackedbar.StackedVerticalBarChart(surface,options)

chart.addDataset(dataSet)

chart.render()

surface.write_to_png('d:\\stackedVerticalBarChart.png')

#水平块图

def draw_stackedhorizontalbarChart(surface, options, dataSet):

chart = pycha.stackedbar.StackedHorizontalBarChart(surface,options)

chart.addDataset(dataSet)

chart.render()

surface.write_to_png('d:\\stackedhorizontalbarChart.png')
