Avoid changing background colors in radar chart

[darinkist]

Hi,

when I create a simple radar cart:

from mplsoccer.radar_chart import Radar

## parameter names
params = ['xAssist', 'Key Passes', 'Crosses Into Box', 'Cross Completion %', 'Deep Completions',
          'Progressive Passes', 'Prog. Pass Accuracy', 'Dribbles', 'Progressive Runs',
          'PADJ Interceptions', 'Succ. Def. Actions', 'Def Duel Win %']

## range values
ranges = [(0.0, 0.15), (0.0, 0.67), (0.06, 6.3), (19.51, 50.0), (0.35, 1.61),
          (6.45, 11.94), (62.9, 79.4), (0.43, 4.08), (0.6, 2.33),
          (4.74, 7.2), (8.59, 12.48), (50.66, 66.67)]

min_range = [0.0,0.0,0.06,19.51,0.35,6.45,62.9,0.43,0.6,4.74,8.59,50.66]
max_range = [0.15, 0.67, 6.3, 50.0,1.61,11.94,79.4,4.08,2.33,7.2,12.48,66.67]

## parameter value
values = [0.11, 0.53, 0.70, 27.66, 1.05, 6.84, 84.62, 4.56, 2.22, 5.93, 8.88, 64.29]


## instantiate object
radar = Radar(params, min_range, max_range)

fig, ax = radar.setup_axis()  # format axis as a radar
rings_inner = radar.draw_circles(ax=ax, facecolor='#ffffff', edgecolor='#000000')  # draw circles
radar_output = radar.draw_radar(values, ax=ax,
                                kwargs_radar={'facecolor': '#709775','alpha': 0.8},
                                kwargs_rings={'facecolor': '#709775', 'alpha':0.8})  # draw the radar

range_labels = radar.draw_range_labels(ax=ax, fontsize=8)
param_labels = radar.draw_param_labels(ax=ax, fontsize=12, **{'color':'#ffffff'})  # draw the param labels

I get the following visualization where (depending on the ring) the color of the polygon is lighter or darker green:

Is there a way to avoid the changing colors of the polygon for every ring?

Nevermind... found my mistake. One can solve it by using the following code:

from mplsoccer.radar_chart import Radar

## parameter names
params = ['xAssist', 'Key Passes', 'Crosses Into Box', 'Cross Completion %', 'Deep Completions',
          'Progressive Passes', 'Prog. Pass Accuracy', 'Dribbles', 'Progressive Runs',
          'PADJ Interceptions', 'Succ. Def. Actions', 'Def Duel Win %']

## range values
ranges = [(0.0, 0.15), (0.0, 0.67), (0.06, 6.3), (19.51, 50.0), (0.35, 1.61),
          (6.45, 11.94), (62.9, 79.4), (0.43, 4.08), (0.6, 2.33),
          (4.74, 7.2), (8.59, 12.48), (50.66, 66.67)]

min_range = [0.0,0.0,0.06,19.51,0.35,6.45,62.9,0.43,0.6,4.74,8.59,50.66]
max_range = [0.15, 0.67, 6.3, 50.0,1.61,11.94,79.4,4.08,2.33,7.2,12.48,66.67]

## parameter value
values = [0.11, 0.53, 0.70, 27.66, 1.05, 6.84, 84.62, 4.56, 2.22, 5.93, 8.88, 64.29]


## instantiate object
radar = Radar(params, min_range, max_range)

fig, ax = radar.setup_axis()  # format axis as a radar
rings_inner = radar.draw_circles(ax=ax, facecolor='#ffffff', edgecolor='#000000')  # draw circles
radar_output = radar.draw_radar(values, ax=ax,
                                kwargs_radar={'facecolor': '#709775','alpha': 0.8},
                                kwargs_rings={'facecolor': '#709775', 'alpha':0.0})  # draw the radar

range_labels = radar.draw_range_labels(ax=ax, fontsize=8)
param_labels = radar.draw_param_labels(ax=ax, fontsize=12, **{'color':'#ffffff'})  # draw the param labels

Nice thanks for posting the solution. 😊
