Reportlab - Pie chart fill colors

Question

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)

Answer 1

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.

1. Using CMYK catColor = PCMYKColor(0,0,0,100)

   pc.slices[0].fillColor = catColor

   See this snippet

2. Using RGB Color catColor = Color(0.10,0.26,0.46)

   pc.slices[0].fillColor = catColor

   • Obviously you do not need CatColor variable, you can put the lines together.
