我有下面的代码图,但我保留在颜色图例中,它不能很好地分开,我无法从图中很好地分辨出差异。我想知道如何将颜色条从例如非常浅的绿色更改为深绿色。所以更加分离。我尝试添加 p9.scale_fill_gradient(low="green",high="darkgreen") ,但它没有用。
import plotnine as p9
pretty_spk = p9.ggplot(data = data_fully_merged, mapping = p9.aes(x='index', y='value', colour = facet_var))+ p9.geom_point(alpha = alpha_scale)
pretty_spk = pretty_spk + p9.facet_grid("gender~outcome")
title_string = season_str.upper() + " " + facet_var + " " + features_str + " curves facetted by gender and outcome"
pretty_spk = pretty_spk + p9.geom_smooth(method = 'loess') + p9.ggtitle(title_string) + p9.scale_fill_gradient(low="green",high="darkgreen")
