我想比较两个系列,即AR1和MA2。他们的价值观非常接近, AR1:
var a = 0xab7878;
var b = 0xda9933;
while(b > a)
{
a = a + 0xFF;
console.log(a.toString(16));
}
MA2:
[1] 3.811470 3.841913 3.885921 3.838163 3.793046 3.781066 3.739327 3.749122
[9] 3.683452 3.716993 3.748613 3.710490 3.680737 3.693812 3.655051 3.652718
[17] 3.677618 3.672693 3.626546 3.625033 3.616690 3.580183 3.575149 3.595116
[25] 3.614835 3.638431 3.689595 3.729338 3.717809 3.690031
我的代码是:
[1] 3.811370 3.842327 3.886117 3.838458 3.792824 3.780851 3.739286 3.748885
[9] 3.683550 3.716546 3.748810 3.710678 3.680557 3.693668 3.655137 3.652521
[17] 3.677604 3.672808 3.626537 3.624852 3.616692 3.580163 3.575021 3.595102
[25] 3.614860 3.638472 3.689649 3.729415 3.717882 3.690009
我的图表:
是否有可能以更重要的方式反映系列之间的这些微小差异?
答案 0 :(得分:2)
这是我们可以做到的一种方式,因此我们不仅可以绘制两个系列的值,还可以绘制系列之间的差异(使用@discipulus建议)。我们使用 grid.arrange
包中的gridExtra
来制作两个面板图。
library(ggplot2)
library(gridExtra)
p1 <- ggplot(dat, aes(x = Date))+
geom_line(aes(y = AR1, colour = 'AR1'))+
geom_line(aes(y = MA2, colour = 'MA2'))+
scale_colour_manual(name = 'Series',
values = c('AR1' = 'blue','MA2' = 'red'))+
ylab('Values')+
ggtitle('Plots of AR1 and MA2')
p2 <- ggplot(dat, aes(x = Date, y = AR1 - MA2))+
geom_line()+
ggtitle('Difference Plot')
grid.arrange(p1, p2, nrow = 1)
