Example 2: Specifying Legend within geomThe ggplot2 package provides several alternatives on the creation of legends. Another alternative is that you specify the col argument within the aesthetics of the geom f
As you can see, we created a graph with a shared legend below the two plots.Figure 1: Two ggplot2 Plots with a Common Legend in R.In this example, we created a common legend for two scatterplots. However, please note that we could also use other types of ggplot2 plots (e.g. ...
You can also give the X and Y coordinate of the legend: legend(3, 5, ...) Note that an equivalent page exist concerning legends with ggplot2. # Create data: a=c(1:5) b=c(5,3,4,5,5) c=c(4,5,4,3,1) # Make a basic graph plot( b~a , type="b" , bty="l" , xl...

It’s also possible to use the R packageggrepel, which is an extension and providesgeomfor ggplot2 to repeloverlapping textlabels away from each other. We’ll start by describing how to use ggplot2 official functions for adding text annotations. In the last sections, examples usingggrepelexten...
3.3.2 气泡图 散点图一般只能较好地展示二维数据,气泡图则是在其基础上另外通过散点的大小来表达第三维变量的数值。同样,也可以使用plot函数绘制气泡图,通过将第三个变量赋予参数cex来控制气泡的大小。 从ggplot2包中的钻石数据集diamonds中随机抽取500个样本,绘制简单气泡图进行演示。执行以下代码得到的结果如图3-19...
french_city %>% ggplot(aes(x = lng, y = lat)) + stat_maptiles( zoom_adj = -1 ) + geom_point(aes(color = admin_name), size = 3, show.legend = FALSE) + theme_void() + mapview() In this case, the zoomed out map actually looks quite nice and provides more readable labels...
在这篇文章中,我们将看到如何使用ggplot2在R编程语言中为多线图添加图例。首先,如果之前没有在R Studio中安装ggplot2包,你需要安装它。 用于创建线状图的函数是 。 geom_line( ) :绘制线条并指定其大小、形状、颜色等。 语法 geom_line(mapping=NULL, data=NULL, stat=”identity”, position=”identity”, ...
