Hello, this is my first question in this% s% s and I have not mastered it yet. I'm learning this wonderful language and now I'm having serious problems plotting a graph using the R package, the data is dates and they do not follow the natural order of dates.

Followthecode

ggplot(tab.OpTT)+geom_area(aes(x=Dia,y=v1,group=1),fill="black")+                                             
geom_area(aes(x = Dia, y = v2, group = 1), fill = "red")+
geom_area(aes(x = Dia, y = v3, group = 1), fill = "blue")+                       
labs(x = "Período de 05/02 á 18/02", y = "Chamadas criadas", title = "teste 
1")

The following data:

Dia;v3;v1;v2;v4;v5
19-jan;44;166;156;8,13;0,15
20-jan;32;74;86;11,65;0
21-jan;29;16;21;13,47;0
22-jan;77;163;104;1,56;0,22
23-jan;31;162;210;3,65;0,2
24-jan;49;179;161;2,39;0,13
25-jan;43;185;192;2,94;0,17
26-jan;29;157;172;4,48;0,15
27-jan;62;127;94;2,33;0,07
28-jan;55;25;41;3,41;0
29-jan;53;238;240;2,47;0,31
30-jan;60;222;222;2,45;0,21
31-jan;60;174;174;2,29;0,47
1-fev;39;166;188;3,69;0,22
2-fev;15;123;148;6,23;0,51
3-fev;12;103;107;8,02;0
4-fev;13;24;27;7,65;0
5-fev;36;221;198;2,89;0,18
6-fev;37;155;157;2,71;0,4
7-fev;25;151;165;4,18;0,25
8-fev;26;149;148;4,05;0,28
9-fev;20;147;153;5,47;0,15

So I tried several ways to correct using the ggplot2 package, but I wanted to put it in the format available in the lubridate table so as not to take up space on the X axis and the DD-M only works with the default using year ( lubridate ). It is also realized that there is a lot of data on the x-axis and it would be good to show just a few samples on that axis, but using the total of data relating to dd-mm-yyyy in the graph construction.

I'm grateful for any help that may come.

obs. the data Dia and v4 are not used.

My suggestion is that dates in R are always represented in yyyy-mm-dd format. This makes it much easier to work with the software when working with this type of data. He needs to understand the exact days with which you are dealing so that the results displayed are correct.

This, I'll create a column with date data in your dataset:

library(lubridate)

tab.OpTT$Dia <- seq(ymd("2018-01-19"), ymd("2018-02-09"), by="days")

With R requires that I put a year in the date, I opted to use 2018. This can be changed later according to your needs.

Now just add the date formatting to the chart you've already done:

ggplot(tab.OpTT)+ 
  geom_area(aes(x = Dia, y = v1, group = 1), fill = "black")+                 
  geom_area(aes(x = Dia, y = v2, group = 1), fill = "red")+
  geom_area(aes(x = Dia, y = v3, group = 1), fill = "blue")+
  labs(x = "Período de 05/02 á 18/02", y = "Chamadas criadas", title = "teste 1") +
  scale_x_date(breaks=seq(min(tab.OpTT$Dia), max(tab.OpTT$Dia), by="1 day"), 
    date_labels="%d/%m", minor_breaks=seq(min(tab.OpTT$Dia),
    max(tab.OpTT$Dia), by="1 day")) +
  theme(axis.text.x = element_text(angle = 90, hjust = 1))

NoticethatIusedanumbertorefertothemonth.IsitpossibletouseotherformattingforthedateifIchangeanargumentwithinscale_x_date:

ggplot(tab.OpTT)+geom_area(aes(x=Dia,y=v1,group=1),fill="black")+                 
  geom_area(aes(x = Dia, y = v2, group = 1), fill = "red")+
  geom_area(aes(x = Dia, y = v3, group = 1), fill = "blue")+
  labs(x = "Período de 05/02 á 18/02", y = "Chamadas criadas", title = "teste 1") +
  scale_x_date(breaks=seq(min(tab.OpTT$Dia), max(tab.OpTT$Dia), by="1 day"), 
    date_labels="%d/%b", minor_breaks=seq(min(tab.OpTT$Dia),
    max(tab.OpTT$Dia), by="1 day")) +
  theme(axis.text.x = element_text(angle = 90, hjust = 1))

Anyway, there are several options. If the solutions I posted here are not ideal, I recommend that you play with scale_x_date until you find something that pleases you.
