Two 、 Draw a normal pie chart
attr = [" shirt ", " Woolen sweater ", " Snow spins unlined upper garment ", " The trousers ", " High heels ", " socks "] v1 = [11, 12, 13, 10, 10, 10] pie1 = Pie(" Pie chart example ") pie1.add("", attr, v1, is_label_show=True,center=[50,50]) page.add(pie1)
3、 ... and 、 Draw a circle
attr = [" shirt ", " Woolen sweater ", " Snow spins unlined upper garment ", " The trousers ", " High heels ", " socks "] v1 = [11, 12, 13, 10, 10, 10] pie2 = Pie(" The pie chart - An example of a doughnut ", title_pos='center') pie2.add( "", attr, v1, radius=[40, 75], label_text_color=None, is_label_show=True, legend_orient="vertical", legend_pos="left", ) page.add(pie2)
Four 、 Draw the pie chart - Rose chart
attr = [" shirt ", " Woolen sweater ", " Snow spins unlined upper garment ", " The trousers ", " High heels ", " socks "] v1 = [11, 12, 13, 10, 10, 10] v2 = [19, 21, 32, 20, 20, 33] pie3 = Pie(" The pie chart - An example of a rose chart ") pie3.add( " goods A", attr, v1, is_random=True, rosetype="radius", is_label_show=True, ) page.add(pie3) attr = [" shirt ", " Woolen sweater ", " Snow spins unlined upper garment ", " The trousers ", " High heels ", " socks "] v1 = [11, 12, 13, 10, 10, 10] v2 = [19, 21, 32, 20, 20, 33] pie4 = Pie(" The pie chart - An example of a rose chart ") pie4.add( " goods B", attr, v2, #center=[75, 50], is_random=True, #radius=[30, 75], rosetype="area", is_legend_show=True, is_label_show=True, ) page.add(pie4)
