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')

二、测试：

1、函数draw_pie(surface, options, dataSet)：

 

2、函数draw_vertical_bar(surface, options, dataSet)：

3、函数draw_horizontal_bar(surface, options, dataSet)：

4、函数draw_line(surface, options, dataSet):

5、函数draw_scatterplot(surface, options, dataSet)：

6、函数draw_stackedverticalbarChar(surface, options, dataSet)：

7、函数draw_stackedhorizontalbarChart(surface, options, dataSet)：
