Meta chart pie code#

X_lst = np.cos(2 * np.pi * np.linspace(start_val, end_val)) # Start value is correct, end value based uses minumum fraction cutoffĮnd_val = start_val + np.maximum( min_slice_val, frc - start_val) Resulting plot with workaround import numpy as np It is ugly and not full-proof, but it helps me for now and (as long as I don't use semi-transparant markers) nobody will know. The zorder in the plotting part is now critically important of course. The workaround is to give the slices a minimum opening angle and let them overlap. Especially for smaller opening angles, when the shape becomes more linear, it chooses a different radius. Thought about it a bit more and the problem may be that the algorithm uses both the opening angle and the radius of the slice to come up with the correct 'size' (i.e.

Meta chart pie code#

The original code I took from this discussion Scatter plots with pie-charts resulting plot Initially I tried increasing to 1000dpi but it did not solve the problem. I was expecting all the pie slices to have the same size. Pie_cat1_lst, pie_cat2_lst, pie_cat3_lst, pie_cat4_lst = get_piechart4_markers( pie_slice_lst )įor xp, yp, mr, sm in zip(x_arr, y_arr, pie_cat1_lst, pie_size_lst):Īx.scatter(xp, yp, marker=mr, s=sm, color='red', alpha=0.9, zorder=10, edgecolors='none')įor xp, yp, mr, sm in zip(x_arr, y_arr, pie_cat2_lst, pie_size_lst):Īx.scatter(xp, yp, marker=mr, s=sm, color='green', alpha=0.9, zorder=10, edgecolors='none')įor xp, yp, mr, sm in zip(x_arr, y_arr, pie_cat3_lst, pie_size_lst):Īx.scatter(xp, yp, marker=mr, s=sm, color='blue', alpha=0.9, zorder=10, edgecolors='none')įor xp, yp, mr, sm in zip(x_arr, y_arr, pie_cat4_lst, pie_size_lst):Īx.scatter(xp, yp, marker=mr, s=sm, color='grey', alpha=0.9, zorder=10, edgecolors='none')įig.savefig(image_file_str, facecolor='w', dpi=1000) Return cat1_lst, cat2_lst, cat3_lst, cat4_lst X_lst = np.cos(2 * np.pi * np.linspace(frc, 1)) X_lst = np.cos(2 * np.pi * np.linspace(frc, frc)) X_lst = np.cos(2 * np.pi * np.linspace(0, frc)) # Define the function to create the markersĭef get_piechart4_markers (fraction_lst): This works, but the size of some of the slices come out slightly different, although the sizes of all slices in a particular pie are exactly the same. Created a scatter plot with pie charts as symbols.
