增加没有随机条ggplot的线宽 [英] Increase line width without stochastic bars ggplot

问题描述

有谁知道是否有可能以平滑的方式增加ggplot2中的线宽而不添加任何伸出的线条？这是我的原始线条图，尺寸增加到5：

 > ggplot（curve.df，aes（x = recall，y = precision，color = cutoff））+ 
> geom_line（size = 1）
  

理想情况下，最终图像看起来类似于PRROC包中的以下图形，但我从那里开始绘制另一个问题，那就是网格线和ablines不对应于轴tickmarks。

在这里我首先称为

 > grid（）
  

然后调用

 > abline（v = seq（0,1，.2），h = seq（0,1，.2））
  

诚实地希望任何方式能够用更宽的线绘制此曲线，以查看清晰的颜色和与轴标记对应的网格。谢谢！

以下是截至.5到.7的数据示例：

解决方案

设置 lineend =round大大改善了情节

  ggplot（curve.df，aes（x = recall，y = precision，color = cutoff））+ 
 geom_line（size = 5，lineend =round）
  

Does anyone know if it's possible to increase the line width in ggplot2 in a smooth fashion without adding random lines that stick out? Here's my original line plot and with size increased to 5:

> ggplot(curve.df, aes(x=recall, y=precision, color=cutoff)) +
>   geom_line(size=1)

Ideally, the final image would look something like the following plot from the PRROC Package, but I have another problem with plotting from there in that gridlines and ablines do not correspond to the axis tickmarks.

Here I first called

> grid()

and then called

> abline(v=seq(0,1,.2), h=seq(0,1,.2))

Honestly would appreciate any way to be able to draw this curve with a wider line to see clear colors and a grid that corresponds to the axis tickmarks. Thanks!

Here's a sample of the data from cutoff .5 to .7:

解决方案

Setting lineend = "round" greatly improves the plot

ggplot(curve.df, aes(x = recall, y = precision, color = cutoff)) +
   geom_line(size = 5, lineend = "round")
