这篇文章主要介绍了python使用reportlab画图示例，大家参考使用吧

准备工作   开发环境：python2.6，reportlab   准备中文字体文件：simsun.ttc   代码：     代码如下: #!/usr/bin/env python2.6 #coding:utf-8   import traceback   from reportlab.graphics.shapes import Drawing from reportlab.graphics.charts.lineplots import LinePlot from reportlab.graphics.charts.textlabels import Label from reportlab.graphics import renderPDF from reportlab.graphics.widgets.markers import makeMarker from reportlab.pdfbase import pdfmetrics, ttfonts   #注意data的类型， #每一个数据点是一个元组 #一条曲线对应一个存储数据点元组的元组 #一个图形可以包含多条曲线，用列表存储曲线元组 data=[((1,100),(2,200),(3,300),(4,400),(5,500)),((1,50),(2,80),(3,400),(4,40),(5,70))]   drawing = Drawing(500, 300)   lp = LinePlot() lp.x = 50 #坐标轴中心坐标 lp.y = 30 lp.height = 250 lp.width = 400 lp.data = data lp.joinedLines = 1 lp.lines.symbol = makeMarker('FilledCircle')   lp.xValueAxis.valueMin = 1 lp.xValueAxis.valueMax = 5 lp.xValueAxis.valueStep = 1   lp.yValueAxis.valueMin = 0 lp.yValueAxis.valueMax = 500 lp.yValueAxis.valueStep = 100 drawing.add(lp)   title = Label() #若需要显示中文，需要先注册一个中文字体 pdfmetrics.registerFont(ttfonts.TTFont("haha", "simsun.ttc")) title.fontName   = "haha" title.fontSize   = 12 title_text = unicode('你好','gbk') #title_text = "abc" title._text = title_text title.x          = 250 title.y          = 280 title.textAnchor ='middle' drawing.add(title)   Xlabel = Label() Xlabel._text = 'x' Xlabel.fontSize   = 12 Xlabel.x          = 480 Xlabel.y          = 30 Xlabel.textAnchor ='middle' drawing.add(Xlabel)   Ylabel = Label() Ylabel._text = "y" Ylabel.fontSize   = 12 Ylabel.x          = 40 Ylabel.y          = 295 Ylabel.textAnchor ='middle' drawing.add(Ylabel)   try:      drawing.save(formats=['gif'],outDir=".",fnRoot="abc") except:      traceback.print_exc()
