我在 R 4.0.2 中有两个连续变量的数据集,分为两组(变量曲线:“Exp.”或“Molecular\ndynamics”)。我用 geom_smooth 图层(ggplot2 3.3.2)绘制它们并按组曲线为它们着色,并且我还设置了该组为它们赋予不同的线型,但然后我使用 scale_linetype_manual 对其进行修改以分别为它们提供虚线和实线线型.
我想做“Exp”。图例粗体的标签。我已经尝试了很多方法(即,其他人的问题的许多答案)来尝试手动重命名图例标签(在 scale_linetype_manual 中添加一个 labels=;在 guides()... 中尝试了一个 override.aes),但最好的我设法做的是获得具有不同标签的重复图例,这些标签既不保留颜色也不保留线型,也不显示“Exp”。粗体字。(我认为问题是我已经使用 scale_xxx 手动调整线型,所以我测试过的关于如何编辑标签的其余答案与我的代码不兼容,我不知道如何弄清楚问题)。
现在的代码:
ggplot() +
geom_smooth(data = data, aes(x=`T(K)`, y=dG, color=Curve, linetype=Curve), size=2, se=FALSE) +
theme_classic() + scale_color_brewer() +
ggtitle('Lysozyme') + xlab('T (K)') + ylab('∆G (kcal/mol)') +
theme(panel.border = element_rect(colour = "black", fill=NA)) +
scale_linetype_manual(values=c("dashed", "solid")) +
theme(text = element_text(family="", size=20),
plot.title = element_text(hjust = 0.5, face="bold", size=20),
axis.title.y = element_text(size=20, margin=margin(r=25)),
axis.title.x = element_text(size=20, margin=margin(t=25)),
axis.text = element_text(size=20, color="black"),
legend.text = element_text(margin = margin(t = 10, b = 10, unit = "pt")),
legend.key.size = unit(2,"line"))
可重现的例子:
