Reportlab - 饼图填充颜色
我正在reportlab 中制作一个简单的饼图。我在文档中找不到如何更改每个单独的馅饼填充颜色。
pie_chart = Drawing(200, 200)
pc = Pie()
pc.x = 65
pc.y = 15
pc.width = 150
pc.height = 150
pc.data = [65,13,12,9,1]
pc.labels = ['Name','Another','Yet Another','Test','Stack']
pc.slices[1]. // This is where I need the fill color property.
pie_chart.add(pc)
renderPM.drawToFile(pie_chart, '/images/temp/pie_chart.png', 'PNG')
p.drawImage('/images/temp/pie_chart.png', 10, 60, width=150, height=150, mask=None)
I am making a simple pie chart in reportlab. I can not find in the docs how to change each individual pies fill color.
pie_chart = Drawing(200, 200)
pc = Pie()
pc.x = 65
pc.y = 15
pc.width = 150
pc.height = 150
pc.data = [65,13,12,9,1]
pc.labels = ['Name','Another','Yet Another','Test','Stack']
pc.slices[1]. // This is where I need the fill color property.
pie_chart.add(pc)
renderPM.drawToFile(pie_chart, '/images/temp/pie_chart.png', 'PNG')
p.drawImage('/images/temp/pie_chart.png', 10, 60, width=150, height=150, mask=None)

好的，有几种方法可以做到这一点。
该属性是 .fillColor，但您必须确保正确地为其提供颜色。下面有两种方式，CMYK和RGB。
使用 CMYK
猫颜色 = PCMYKColor(0,0,0,100)
pc.slices[0].fillColor = catColor
查看此代码段
使用 RGB 颜色
猫颜色 = 颜色(0.10,0.26,0.46)
pc.slices[0].fillColor = catColor
查看有关颜色的详细信息 这里< /a>（reportlab 文档，请参阅第 23 页）
Ok there is a couple ways to do this.
The property is .fillColor, but you have to make sure you provide the color to it correctly. Below are two ways, with CMYK and RGB.
Using CMYK
catColor = PCMYKColor(0,0,0,100)
pc.slices[0].fillColor = catColor
See this snippet
Using RGB Color
catColor = Color(0.10,0.26,0.46)
pc.slices[0].fillColor = catColor
