  • 0

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)

    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.

    View more info about colors here (reportlab docs, see page 23)
