Donde ggplot2.continuous.fill es el valor predeterminado de la escala de color del continuo. El argumento del método scale_fill_continuous puede ser Viridis o gradient. Probemos un ejemplo de este método. Primero, cargue el paquete ggplot2 y cree un gráfico ggplot. library(ggplot2) Demo...

如果你的数据确实是连续的,并且你想根据这些连续值设置填充颜色,你应该使用scale_fill_gradient()、scale_fill_gradient2()或scale_fill_viridis()等适合连续值的填充比例尺函数。 如果你确实想使用scale_fill_manual(),你需要先将连续数据转换为离散数据(如通过分组或分类)。 根据转换后的数据或选择的填充比例尺函...
