Expanding discrete variable x-axis

Hello, everyone!

I am producing a line graph that displays a participant's train of thought (individual words) before and after reading a story. The x-axis is to have each word produced with subjective ratings from an independent rater on a scale of 0 to 7 on the y-axis. The subjective ratings reflect what the rater presumes the word is related to the story read or not. A 0 indicates that the word is not directly related to the story, and a 7 is most definitely related to the story.

Each participant can produce as many words as possible within a 5-minute time limit. You will notice below that the free associate word x-axis for the participant is illegible. This is because the participant produced 299 words for the pre-story condition. The post-story has 254 words, with the overall number of observations at 553.

I write to ask for guidance on how to expand the x-axis as the words are considered discrete variables since they are ordered from the first word produced to the second, third, etc. Eventually, I plan to stack 5 separate line graphs into one line graph to show the differences between 5 different raters' ratings for the same participant's free associate word chain. I also plan to showcase the differences pre and post-story.

The data frame pA_CF_pre code originates from these lines below of the original particip_a data frame. The particip_a data frame is a larger data frame with all raters.

pA <- particip_a[c(7:11)] #selecting only the columns of interest (word, phase, order)
pA[pA == "1 (not at all)"] <- "1"
pA[pA == "7 (very much)"] <- "7"
pA <- as.data.frame(sapply(pA, as.numeric))
pA$word <- particip_a$word
pA$phase <- particip_a$phase
pA$order <- particip_a$order
pA <- pivot_longer(pA,cols=1:5,names_to="raters", values_to="ratings")
pA <- as.data.frame(pA)

My code to produce the line graph is this:
pA_CF_pre <- subset(pA, raters == "CF" &phase == "pre-story" & ratings)
pA_CF_plot_pre <- ggplot(pA_CF_pre, aes(x=as.factor(word), y=ratings))+geom_line(group=1)+
theme(axis.text.x = element_text(angle=90, hjust=0.5, vjust=0.5))+
xlab("free associate word")+
ggtitle("Participant A free associates (pre-story) and rater1 ratings")
pA_CF_plot_pre+scale_x_discrete(limits=pA_CF_plot_pre$word)

My plot currently looks like this:

Any help is welcome and much appreciated. Thank you so much!

Hi @cmariecan, is better help you if put a reproducible example of data.

https://community.rstudio.com/t/faq-draft-use-the-reprex-package-to-prepare-your-reproducible-example-for-posting/47264

Paste the result of dput(pA_CF_pre[ 1:30, ])

Try with this lines:

pA_CF_pre$word   <-  as.factor(pA_CF_pre$word)

A_CF_plot_pre <- ggplot(pA_CF_pre, aes(x=reorder(word, - ratings) y=ratings))+geom_line(group=1)+
theme(axis.text.x = element_text(angle=90, hjust=0.5, vjust=0.5))+
xlab("free associate word")+
ggtitle("Participant A free associates (pre-story) and rater1 ratings") 

pA_CF_plot_pre+scale_x_discrete(limits=pA_CF_plot_pre$word)

Thank you for your feedback, @M_AcostaCH! My apologies for not doing so the first time.

The result of dput(pA_CF_pre[ 1:30, ]) is:

The plot produced with your above code is not exactly what I am looking for. Thank you for your suggestion!

Here is a reprex example of my initial inquiry for the line graph. I attached a link here for a CSV file for the free associate words for my working condition.

library(plyr)
library(Hmisc)
library(ggcorrplot)
library(psych)
library(tidyverse)
library(ggplot2)
library(ggthemes)
library(cowplot)
library(gridExtra)
library(patchwork)

#load csv file for list of free associates
free_associates <- read.csv("[insert csv file]/sample_word.csv")
head(free_associates)

#input order, phase, and raters columns for pre-story condition
order <- c(291:299,1:10,31:40,21:30,111:120,231:240,81:90,11:20,101:110,181:190,121:130,281:290,261:280,51:60,221:230,251:260,161:170,191:210,91:100,141:150,241:250,41:50,211:220,131:140,61:70,171:180,151:160,71:80)
phase <- rep(c("pre-story"),299)
raters <- rep(c("CF"),299)
participant_A <- data.frame(free_associates,phase,raters,order)

#convert CF chr vectors to numeric
participant_A$CF[participant_A$CF == "1 (not at all)"] <- "1"
participant_A$CF[participant_A$CF == "7 (very much)"] <- "7"
participant_A$CF <- as.numeric(sapply(participant_A$CF, as.numeric))
colnames(participant_A)[2] = "rating" #rename CF to ratings

#participant_A$word <- as.factor(participant_A$word) -- not necessary?
free_associates_pre <- ggplot(participant_A, aes(x=as.factor(word), y=rating))+geom_line(group=1)+
theme(axis.text.x = element_text(angle=90, hjust=0.5))+
xlab("free associate word")+
ggtitle("Participant A free associates and rater1 ratings")
free_associates_pre

Looking forward to any further suggestions! Thank you so much.

Kind regards,

Maybe you could make groups in x axis.

What plot you want, you could draw?

Hello @M_AcostaCH, thank you so much for your continued support!

The plot I was looking for was similar to the above I posted; the x-axis extended to show all of the words. It turns out the solution was simpler than I expected! Using the export to PDF process, I increased the width of the dimensions (e.g., 40 inches). Here's a link to view the desired output (I cannot embed the photo in this post, I apologize!).

Thank you so much for your help! Your suggestion to make groups is also possible. It is something I will consider for the next steps in my analyses. Thank you again!

Kind regards,
