你如何訂購ggplot

幾個月，我叫YY該數據幀：你如何訂購ggplot

structure(list(Time = structure(c(1209096000, 1238731200, 1272600000, 
1301666400, 1335794400, 1364835600, 1218772800, 1250222400, 1280808000, 
1314028800, 1346421600, 1377835200, 1229317200, 1262235600, 1291352400, 
1324047600, 1355497200, 1385960400, 1204261200, 1235710800, 1265950800, 
1298646000, 1328281200, 1360940400, 1199250000, 1232082000, 1263186000, 
1295017200, 1326466800, 1357149600), class = c("POSIXct", "POSIXt" 
), tzone = ""), Peak_Logons = c(472452L, 398061L, 655849L, 881689L, 
873720L, 1278295L, 340464L, 520943L, 1995150L, 883184L, 931721L, 
1098553L, 405193L, 638301L, 734635L, 1254951L, 962391L, 1126432L, 
316200L, 477407L, 674884L, 812793L, 898550L, 1541478L, 291564L, 
394967L, 902076L, 916832L, 878264L, 918102L), Year = c("2008",

"2013", "2008", "2009", "2010", "2011", "2012", "2013", "2008", 
"2009", "2010", "2011", "2012", "2013"), Month = c("April", "April", 
"April", "April", "April", "April", "August", "August", "August", 
"August", "August", "August", "December", "December", "December", 
"December", "December", "December", "February", "February", "February", 
"February", "February", "February", "January", "January", "January", 
"January", "January", "January")), .Names = c("Time", "Peak_Logons", 
"Year", "Month"), row.names = c(35479L, 30535L, 23645L, 15248L, 
49696L, 8077L, 24651L, 13098L, 20204L, 47450L, 41228L, 20740L, 
28049L, 9739L, 2636L, 50230L, 43746L, 3435L, 38091L, 28351L, 
7382L, 3343L, 47824L, 45481L, 23951L, 29664L, 10024L, 4545L, 
38808L, 44205L), class = "data.frame")

我希望做的就是創建一個熱地圖，同比y軸和月在x軸。

我這樣做：

ggplot(yy ,aes(Month, Year, fill=Peak_Logons)) + 
    geom_tile() + 
    theme_bw() + 
    guides(fill = guide_legend(keywidth = 5, keyheight = 1)) + 
    theme(axis.text.x = element_text(size=10, angle=45, hjust=1))

這有點兒工作，但在x軸上月不從一月，二月，三月，四月......月訂購。

他們是爲了aphabetically從四月，八月等

我怎麼會爲了X軸1〜12月？
有沒有辦法改變默認的顏色，它看起來像使用藍色陰影？
我可以使用geom_tiles文字嗎？我想在瓦片中插入Time和Peak_Logons。

我真的很感謝任何見解。

對於第一個問題，你有沒有嘗試第一融通月變量？ 'yy $ Month < - factor（yy $ Month，month.name）'也許。 – A5C1D2H2I1M1N2O1R2T1

@AnandaMahto，謝謝你的工作。 – user1471980

使用重新排序來安排您的軸標籤。我創建了一個包含月份索引的新列。
geom_text添加文本。也許你應該玩文字大小。
scale_fill_gradientn更改填充顏色。又見scale_fill_gradientn

enter image description here

dat.m <- data.frame(Month=months(seq(as.Date("2000/1/1"), 
       by = "month", length.out = 12)),month.id = 1:12) 

yy <- merge(yy,dat.m) 
library(ggplot2) 
ggplot(yy ,aes(reorder(Month,month.id), Year, fill=Peak_Logons)) + 
    geom_tile() + 
    theme_bw() + 
    guides(fill = guide_legend(keywidth = 5, keyheight = 1)) + 
    theme(axis.text.x = element_text(size=10, angle=45, hjust=1)) + 
    geom_text(aes(label=paste(Peak_Logons,format(Time,"%H"),sep='-'))) + 
    scale_fill_gradient(low = "yellow", high = "red")

你似乎認爲月份是一個有序的因素。你應該讓一個在R：

Month = c("April", "April", 
      "April", "April", "April", "April", "August", "August", "August", 
      "August", "August", "August", "December", "December", "December", 
      "December", "December", "December", "February", "February", "February", 
      "February", "February", "February", "January", "January", "January", 
      "January", "January", "January") 

Month.ordered <- ordered(Month, month.name) 
#[1] April April April April April April August August August August August August December December December December 
#[17] December December February February February February February February January January January January January January 
#Levels: January < February < March < April < May < June < July < August < September < October < November < December
