改变气球图中点的大小并保持零值 [英] Changing size of the dots in a balloon plot and keeping zero values

问题描述

对于这些数据

  Data<  -  structure（list（ObsVal = c（22L，50L，8L，15L， 54L，30L，11L，90L，
 6L，53L，9L，42L，72L，40L，60L，58L，1L，20L，37L，2L，50L，
 68L，20L，19L，58L， 5L），Porp = c（0.0909090909090909,0.02,0，
0,0,0,0.2272727272727273,0.455555555555556,0,0.452830188679245，
 0.111111111111111,0.404761904761905,0,0.025,0.0166666666666667,0 
 0.120689655172414 ，0,0.1,0.108108108108108,0,0,0.0294117647058824，
 0,0,0.310344827586207,0），Pred = c（26,52,6,15,39,30，
 13,85， 8,62,5,48,92,52,71,68,1,28,47,1,41,106，
 29,19,39,7）），.Names = c（ObsVal ，Porp，Pred），class =data.frame，row.names = c（NA，
 -26L））
  

和这段代码

  require（ggplot2）
p< -  ggplot（data，aes（x = ObsVal，y = Pred，size = Porp））+ 
 geom_point（）+ 
 geom_smooth（method = lm，color =red）+ 
 theme_bw（）+ 
指南（大小= FA LSE）
p 
  

我可以制作这张图

但点数太小。当我通过代码增加尺寸时，可以使用

  p + scale_size_area（max_size = 10）
  

圆点变大，但是我忽略了Porp为零的值。

我试着加1到所有Porp值，但大小都是一样的。

可以像第二张图一样增加点的大小，但也包括点数Porp为零？

解决方案

您可以尝试使用 scale_size_continuous 及其范围参数。例如。像这样：

  p + scale_size_continuous（range = c（2，10））
  

With these data

Data <- structure(list(ObsVal = c(22L, 50L, 8L, 15L, 54L, 30L, 11L, 90L, 
6L, 53L, 9L, 42L, 72L, 40L, 60L, 58L, 1L, 20L, 37L, 2L, 50L, 
68L, 20L, 19L, 58L, 5L), Porp = c(0.0909090909090909, 0.02, 0, 
0, 0, 0, 0.272727272727273, 0.455555555555556, 0, 0.452830188679245, 
0.111111111111111, 0.404761904761905, 0, 0.025, 0.0166666666666667, 
0.120689655172414, 0, 0.1, 0.108108108108108, 0, 0, 0.0294117647058824, 
0, 0, 0.310344827586207, 0), Pred = c(26, 52, 6, 15, 39, 30, 
13, 85, 8, 62, 5, 48, 92, 52, 71, 68, 1, 28, 47, 1, 41, 106, 
29, 19, 39, 7)), .Names = c("ObsVal", "Porp", "Pred"), class = "data.frame", row.names = c(NA, 
-26L))

and this code

require(ggplot2)
p <- ggplot(Data, aes(x=ObsVal, y=Pred, size=Porp))+
    geom_point()+
    geom_smooth(method=lm, color="red")+
    theme_bw()+
    guides(size=FALSE)
p

I can make this plot

but the dots are too small. When I increase the size with the code

p+scale_size_area(max_size=10)

The dots get larger, but I loose the values where Porp is zero.

I tried to add 1 to all Porp values, but then the sizes were all the same.

It is possible to increase the size of the dots as in the 2nd fig, but also include points were Porp is zero?

解决方案

You may try to use scale_size_continuous and its range argument. E.g. something like this:

p + scale_size_continuous(range = c(2, 10))
