图例filled.contour图

Question

我试图用filled.contour创建一个等高线图，我想改变图例标题和标签的大小以及图例本身的大小。我已经有了我的数据的代码，它非常类似于火山的例子(更容易复制)。

data(volcano)
filled.contour(volcano, color = terrain.colors, asp = 1)# simple

x <- 10*1:nrow(volcano)
y <- 10*1:ncol(volcano)
filled.contour(x, y, volcano, color = terrain.colors,
               plot.title = title(main = "The Topography of Maunga Whau",
                                  xlab = "Meters North", ylab = "Meters West"),
               plot.axes = { axis(1, seq(100, 800, by = 100))
                 axis(2, seq(100, 600, by = 100)) },
               key.title = title(main="Height\n(meters)"),
               key.axes = axis(4, seq(90, 190, by = 10),asp=1))# maybe also asp=1

我尝试过添加cex和pch参数，但似乎不起作用。

key.title = title(main="Height\n(meters)",cex=0.5,pch = 1)

如有建议，将不胜感激。

谢谢。

Answer 1

使用par(cex.main)在plot.title和key.title中

filled.contour(x, y, volcano, color = terrain.colors,
               plot.title = {par(cex.main=1);title(main = "The Topography of Maunga Whau",
                                  xlab = "Meters North", ylab = "Meters West")},
               plot.axes = { axis(1, seq(100, 800, by = 100))
                 axis(2, seq(100, 600, by = 100)) },
               key.title = {par(cex.main=0.3);title(main="Height\n(meters)")},
               key.axes = axis(4, seq(90, 190, by = 10),asp=1))# maybe also asp=1
