GGPLOT2:如何在ggplot()脚本中绘制特定选择 [英] GGPLOT2: how to plot specific selections inthe ggplot() script

问题描述

这是一个名为 P 的大型数据集的高峰，那里有10个拥有不同商店( SHP )的特许经营权( CS )有几个数值.数据集按星期( WK )2 tm 52的顺序列出它们.它创建一个大文件.仅进入前6行的峰:

This is a peak into a large dataset named P, where there are 10 concessionaries (CS) that have different shops (SHP) with several numeric values. The dataset lists them ordered by week (WK) 2 tm 52. It creates a large file. A peak into just the 6 first rows:

WK,MND,CS,SHP,RevCY,RevLY,TCY,TLY,ACY,ALY
=========================================
2,JAN,AAA,AAA Shop 1,16834,16686,1837,1983,2853,3002 

2,JAN,AAA,AAA Shop 2,95919,114696,9742,11813,20521,24673

2,JAN,BBB, BBB shop 1,93428,92212,7647,7857,18436,17984

2,JAN,BBB, BBB Shop 2,30600,35831,2748,3063,5579,6408

2,JAN,CCC, CCC Shop 1, 65229,78761,6074,7172,13852,16706

2,JAN,CCC, CCC Shop 2,465,754,73,118,92,162

我很难仅绘制与 SHP == AAA 有关的值.

I have difficulties plotting just the values that concern fi SHP==AAA.

p <- ggplot(P, aes(WK, RevCY)) + geom_bar(stat="identity")

这正在绘制所有商店和所有 CS .因此，潜在的问题是要了解如何仅从 CS = AAA 中绘制商店( SHP ).假设在 ggplot()+ geom_bar(stat ="identity")的x轴上是星期( WK )，在y轴上是 RevCY )代码.

This is plotting all shops and all CS. So the underlying question is to understand how I can plot only the shops (SHP) from CS=AAA. Let's say with the weeks (WK) on the x-axis and RevCY on the y-axis in the ggplot() + geom_bar(stat="identity") code.

这是正确的方向吗?:

p <- ggplot(P[P$CS=="AAA"], aes(WK, RevCY)) + geom_bar(stat="identity")

因此，无需创建各种子集即可直接进入 ggplot()代码.希望我的问题清楚.

So without creating all kinds of subsets and straight into the ggplot() code. Hope my question is clear.

推荐答案

这对您有帮助吗?

ggplot(t, aes(WK, RevCY)) + geom_bar(data=subset(t,CS=="AAA"),stat="identity")
