将图表添加到Reportlab PDF [英] Adding Graph to Reportlab PDF

问题描述

我已经看到很多reportlab绘图示例。生成图形不是问题，我似乎无法弄清楚如何在pdf上显示图形。

这里是代码：

  buffer = StringIO（）
p = canvas.Canvas（buffer，pagesize = letter）
 
 ### ##有问题的代码开始
 
d =绘图（200，100）
 pc = Pie（）
 pc.x = 65 
 pc.y = 15 
 pc.width = 70 
 pc.height = 70 
 pc.data = [10,20,30,40,50,60] 
 pc.labels = ['a' ，'b'，'c'，'d'，'e'，'f'] 
 pc.slices.strokeWidth = 0.5 
 pc.slices [3] .popout = 10 
 pc.slices [3] .strokeWidth = 2 
 pc.slices [3] .strokeDashArray = [2,2] 
 pc.slices [3] .labelRadius = 1.75 
 pc.slices [ 3] .fontColor = colors.red 
 d.add（pc）
 
 p.drawPath（d）###这不工作，但需要类似的东西
 
 #####问题结束代码
 
 p.showPage（）#Page两个
 
 p.save（）＃使用Response\\保存PDF和返回值\\ 
 
 pdf = buffer.getvalue（）
 buffe r.close（）
 response.write（pdf）
 return response 
  

这是我如何显示文字。
p.setFillColorRGB（1,1,1）
header = p.beginText（100，765）
header.textLine（页面标题文本）
p.drawText（标题）

解决方案

我写了这段时间以前，但它是网站上最受欢迎的文章之一，所以我猜它适用于一些。

如果还不足以让你通过，让我知道，当我有更多的时间时，我会回来帮助更多。

I have seen many reportlab graphing examples. Generating the graph is not the problem, I can't seem to figure out how to display the graph on the pdf.

Here is the code:

buffer = StringIO()
p = canvas.Canvas(buffer, pagesize = letter)

##### Beginning of code in question

d = Drawing(200, 100)
pc = Pie()
pc.x = 65
pc.y = 15
pc.width = 70
pc.height = 70
pc.data = [10,20,30,40,50,60]
pc.labels = ['a','b','c','d','e','f']
pc.slices.strokeWidth=0.5
pc.slices[3].popout = 10
pc.slices[3].strokeWidth = 2
pc.slices[3].strokeDashArray = [2,2]
pc.slices[3].labelRadius = 1.75
pc.slices[3].fontColor = colors.red
d.add(pc)

p.drawPath(d) ### THIS DOES NOT WORK, but need something similar

#####End of Code in Question

p.showPage() #Page Two

p.save() # Saves the PDF and Returns with Response\

pdf = buffer.getvalue()
buffer.close()
response.write(pdf)
return response

This is how I display text. p.setFillColorRGB(1,1,1) header = p.beginText(100, 765) header.textLine("Page Heading Text") p.drawText(header)

解决方案

I wrote this some time ago, but it's been one of the most popular articles on the site, so I guess it works for some.
