I am plotting a filled contour plot usingggplot2, and I'd like to adjust the legend label position. I am not sure if this is doable inggplot2? The label position in Figure 3 has moved up compared with Figure 2. The label in Figure 3 aligns with the border of the key,...

在上面的例子中,各种属性映射由ggplot函数执行,只需要加一个图层,使用geom_point()告诉ggplot要画散点,于是所有的属性都映射到散点上。 geom_point()完成的就是几何对象的映射,ggplot2提供了各种几何对象映射,如geom_histogram用于直方图,geom_bar用于画柱状图,geom_boxplot用于画箱式图等等。 不同的几何对象,要求的...
The goal of this article is to describe how to change the color of a graph generated using R software and ggplot2 package. A color can be specified either by name (e.g.: “red”) or by hexadecimal code (e.g. : “#FF1234”). The different color systems available in R are describe...

I'm trying to create a scatter plot in ggplot2 that has the usual numerical axis labels, but some helper text below it that explains what it means to be more left or right on the figure. The rub is that I want to include both an arrow and a linebreak and ...
