ggplotly and geom_text vjust/hjust - how to achieve this static plot? - r

I've created the following plot which I'm quite pleased with when it's static - however, I wanted to make it interactive so when people hover over you can see the seasons (like pudding.cool has done here. The static plot I have:
The code to achieve this is:
character_sentiment_season_adj %>%
mutate(sent_dummy = ifelse(sentimentc < 0, "More Negative", "More Positive")) %>%
mutate(character = reorder(character, avg_sentiment)) %>%
ggplot(aes(character, sentimentc, hoverinfo = season)) +
geom_point(colour = "#666666", size = 4, fill = "#f2f2f2", shape = 21) +
coord_flip() +
geom_hline(yintercept = 0, alpha = 0.2) +
geom_point(aes(character, avg_sentiment, color=avg_sentiment), shape = 21, colour = "#262626", fill = "#ff9933", size = 4) +
geom_text(aes(label = character),
size = 3,
data = subset(character_sentiment_season_adj, sentimentc == max_sentiment),
hjust = -0.5,
vjust = 0.3) +
labs(title = "How negative are The Office (US) characters?",
subtitle = "Sentiment of each character based on bing sentiment scores") +
theme(axis.title.x = element_blank(),
axis.title.y = element_blank(),
axis.text.y = element_blank(),
axis.text.x = element_blank(),
axis.ticks = element_blank(),
axis.line = element_blank(),
panel.background = element_rect(fill = "white"),
plot.title = element_text(hjust = 0.5, face = "bold"),
plot.subtitle = element_text(hjust = 0.5),
plot.caption = element_text(size = 6)
)
However, when I turn it into a Plotly, it starts looking like this:
I've tried using style already so the code for the above plotly is:
ggplotly(p,
tooltip = "season") %>% style(textposition = "right")
I'm quite new to R. I am happy to use a package other than ggplotly if necessary.

Aligning text on horizontal bar chart

I've come across several threads pointing out how to annotate bar charts, but I've tried a number of iterations of this code and can't seem to get the text left justified, starting at 0% on the x axis. I've tried to change hjust to "left", 0.95, and progressively larger numbers - none of them have the text tethered to the x origin.
dummy_data <- tibble(Proportion = c(0.87, 1),
`Person of Interest` = c("Person B", "Person A"))
dummy_data %>%
ggplot(aes(x = Proportion, y = `Person of Interest`,
fill = `Person of Interest`,
label = paste0(`Person of Interest`, "~", scales::percent(Proportion))))+
geom_col(width = 0.5) +
geom_text(position = position_dodge(width = .9), # move to center of bars
vjust = 0, # nudge above top of bar
hjust = "top",
size = 4.5,
colour = "white",
fontface = "bold") +
scale_x_continuous(labels = scales::percent,
limits = c(0, 1.01),
expand = c(0, 0)) +
ggthemes::theme_economist(horizontal = F) +
scale_fill_manual(values = alpha(c("black", "#002D62"), .5)) +
ggtitle("Lack of Skill") +
theme(title = element_text("Lack of Skill"),
plot.title = element_text(hjust = 0.5, face = "italic"),
axis.title.y = element_blank(),
axis.text.y = element_blank(),
axis.ticks.y = element_blank(),
axis.title.x = element_blank(),
axis.text.x = element_text(hjust = 0.25),
legend.position="none",
aspect.ratio = 1/3)
I've often found text data with ggplot maddening - a huge thanks to anyone willing to take a look.
Try this approach that is close to what you want. Your themes can be producing the issues with placing the labels:
#Code
dummy_data %>%
ggplot(aes(x=`Person of Interest`,
y=Proportion,
fill=`Person of Interest`,
label = paste0(`Person of Interest`, "~", scales::percent(Proportion))))+
geom_bar(stat = 'identity')+
geom_text(aes(y=0.13),
size = 4.5,
colour = "white",
fontface = "bold")+coord_flip()+
scale_y_continuous(labels = scales::percent,
limits = c(0, 1.01),
expand = c(0, 0)) +
ggthemes::theme_economist(horizontal = F) +
scale_fill_manual(values = alpha(c("black", "#002D62"), .5)) +
ggtitle("Lack of Skill") +
theme(title = element_text("Lack of Skill"),
plot.title = element_text(hjust = 0.5, face = "italic"),
axis.title.y = element_blank(),
axis.text.y = element_blank(),
axis.ticks.y = element_blank(),
axis.title.x = element_blank(),
axis.text.x = element_text(hjust = 0.25),
legend.position="none",
aspect.ratio = 1/3)

How to draw an empty ggplot with just the legend?

My question is very similar to this question, but it's not the same.
I am looking for a way to create an empty ggplot with just the legend. However, in contrast to the autohor of the question I linked at the top, I actually need to create just the legend with no plot area included in the image.
I tried the following code:
ggplot(NULL, aes(color = ""))+
geom_blank()+
scale_color_manual(values = "black", labels = "Something")+
guides(color = guide_legend())+
theme(legend.box.background = element_rect(color = "black"))
But I'm getting the opposite of what I want - I am getting an empty plot area with no legend, like this:
And I would like my end result to look like this (I drew this in Paint):
Any help would be appreciated!
You can make a normal plot, then play with theme to achieve the desired result.
library(ggplot2)
ggplot(data.frame(x = 1, y = 1, colour = 'Something'), aes(x, y, fill = colour))+
geom_point(alpha=0, shape = 0)+ # completely transparent rectangular point
scale_fill_manual(values='black', drop=FALSE) +
guides(fill = guide_legend(override.aes = list(alpha=1, size = 40)))+ # showing the point in the legend
theme(axis.title = element_blank(),
axis.text = element_blank(),
axis.ticks = element_blank(),
legend.position = c(0.5, 0.5), # move the legend to the center
legend.title = element_blank(),
legend.text = element_text(size = 40),
legend.key = element_rect(fill='NA'),
panel.grid = element_blank(),
panel.border = element_rect(colour = "black", fill='white', size=1)
)
Get the legend how you want it to look, then extract it with cowplot::get_legend:
library(grid)
library(cowplot)
library(ggplot2)
grid.newpage()
grid.draw(get_legend(
ggplot(data.frame(x = 1, y = 1), aes(x, y, fill = "Something")) +
geom_col(size = 20)+
scale_fill_manual(values = "white", labels = "Something", name = "") +
theme_bw() +
theme(legend.box.background = element_rect(color = "black"),
legend.title = element_text(size = 30),
legend.key.size = unit(60, "points"),
legend.text = element_text(size = 24),
legend.key = element_rect(colour = "black"),
legend.box.margin = margin(20, 20, 20, 20))))

Pesky border around a grob inset map

I made this map and it's nearly perfect except for the inset map has this pesky white borer around it. I would like for the inset to just have the black line border of the actual panel border, but not that white background that's coming along with it. Additionally, my panel.grid element is not displaying above the land mass I have plotted, and would like for it to display above the land mss (pictured in the main map in light gray). I have my panel.grid = element_line(color = "darkgray") in my main map, but it's still not displaying the way I intended. The same goes for my scale bar and my north arrow. Here is a screenshot of my plot:
And this is the code that I used to generate my map:
MainMap <- ggplot(QOI) +
geom_sf(aes(fill = quadID)) +
scale_fill_manual(values = c("#6b8c42",
"#70b2ae",
"#d65a31")) +
labs(fill = "Quadrants of Interest",
caption = "Figure 1: Map depicting the quadrants in the WSDOT project area as well as other quadrants of interest in the Puget Sound area.")+
ggtitle("WSDOT Project Area and Quadrants of Interest") +
geom_sf(data = BCWA_land) +
xlim (-123.1, -121.4) +
ylim (47.0, 48.45) +
theme_bw()+
theme(panel.grid = element_line(color = "darkgray"),
legend.text = element_text(size = 11, margin = margin(l = 3), hjust = 0),
legend.position = c(0.95, 0.1),
legend.justification = c(0.85, 0.1),
legend.background = element_rect(colour = "#3c4245", fill = "#f4f4f3"),
axis.title = element_blank(),
plot.title = element_text(face = "bold", colour = "#3c4245", hjust = 0.5, margin = margin(b=10, unit = "pt")),
plot.caption = element_text(face = "italic", colour = "#3c4245", margin = margin(t = 7), hjust = 0, vjust = 0.5))
MainMap
InsetRect <- data.frame(xmin=-123.2, xmax=-122.1, ymin=47.02, ymax=48.45)
InsetMap <- ggplotGrob( ggplot( quads) +
geom_sf(aes(fill = "")) +
scale_fill_manual(values = c("#eefbfb"))+
geom_sf(data = BCWA_land) +
scale_x_continuous(expand = c(0,0), limits = c(-124.5, -122.0)) +
scale_y_continuous(expand = c(0,0), limits = c(47.0, 49.5)) +
geom_rect(data = InsetRect,aes(xmin=xmin, xmax=xmax, ymin=ymin, ymax=ymax),
color="#3c4245",
size=1.25,
fill=NA,
inherit.aes = FALSE) +
theme_bw()+
theme(legend.position = "none",
panel.grid = element_blank(),
axis.title = element_blank(),
axis.text = element_blank(),
axis.ticks = element_blank(),
panel.background = element_blank()))
InsetMap
Figure1 <- MainMap +
annotation_custom(grob = InsetMap, xmin = -122.2, xmax = -121.3,
ymin = 47.75, ymax = 48.5) +
scalebar(x.min = -122.7, x.max = -122.5, y.min = 46.95, y.max = 47.1, location = "bottomright",
transform = TRUE, dist = 10, dist_unit = "km", st.size = 2, st.bottom = TRUE)
Figure1
In the inset map code, I had set the panel.background = element_blank() so I'm not sure why I'm still getting a white background/border around my inset.
Please let me know if you need the data that I used to generate these maps. It's a larger file and so the character limit on SO limits what I can put up. Even if I trim the data down, because they are polygon shape files a single data row is pretty cumbersome to share.
Any insight would be much appreciated!

Adjusting white space between titles and the edge of the plot

I want to create space between the titles (the axis title and the plot title) and the edge of the plot. I tried vjust on axis.title and plot.title with no luck. Nothing really changed in the plot when I tried various values for vjust. I also tried plot.margin, but nothing seemed to happen with it either.
Data:
data = data.frame(Category = c(0,1), value = c(40000, 120000))
data$Category = factor(data$Category, levels = c(0,1), labels = c("One-time", "Repeat"))
Plot:
p = ggplot(data, aes(Category, Value)) +
geom_bar(stat = "identity", width = 0.5, position=position_dodge(width=0.9)) +
geom_text(aes(label=Value), position=position_dodge(width=0.9), family = "mono", vjust=-0.5) +
ggtitle("Title") +
scale_y_continuous(expand = c(0,0), limits = c(0,150000)) +
scale_x_discrete(expand = c(0,0), limits = c("One-time", "Repeat")) +
xlab("X axis Title") +
ylab("Y axis Title")
Theme:
p + theme(
panel.grid.major = element_line(linetype = "blank"),
panel.grid.minor = element_line(linetype = "blank"),
axis.title = element_text(family = "sans", size = 15),
axis.text = element_text(family = "mono", size = 12),
plot.title = element_text(family = "sans", size = 18),
panel.background = element_rect(fill = NA)
)
You want to do this using margin
p + theme(
panel.grid.major = element_line(linetype = "blank"),
panel.grid.minor = element_line(linetype = "blank"),
axis.title.x = element_text(family = "sans", size = 15, margin=margin(30,0,0,0)),
axis.title.y = element_text(family = "sans", size = 15, margin=margin(0,30,0,0)),
axis.text = element_text(family = "mono", size = 12),
plot.title = element_text(family = "sans", size = 18, margin=margin(0,0,30,0)),
panel.background = element_rect(fill = NA)
)
Note that margin requires a four inputs and they specify the space in the order top,right,bottom,left. Also note I'm using the developmental ggplot2 version so my title default is left justified. 'hjust' and 'vjust' worked in older versions of ggplot2.
You can also give a "-ve" value to margin argument to pull the title closer to the plot.
gg_1 +
theme(plot.title = element_text(size = 12,
hjust = 0.5,
family = fam_3,
face = "bold",
margin = margin(0,0,-10,0))

Add legend to ggplot object (why two legends?)

I created a ggplot2 object:
a <- replicate(8,rnorm(100))
colnames(a) <- letters[1:8]
b < -melt(a,id.vars=1:1)
colnames(b) <- c("c","variable","value")
ggplot(b,aes(x = c,y = value, colour = variable, linetype = variable)) +
geom_line()+
geom_point(aes(shape = factor(variable)), size = 1.7) +
scale_x_continuous(limits = c(-1, 1),
breaks = seq(-1, 1, 0.1),
expand=c(0.01, 0.01)) +
scale_y_continuous(limits = c(-1, 1),
breaks = seq(-1, 1, 0.1),
expand = c(0.01, 0.01))+
theme_bw(base_size = 12, base_family = "Helvetica") +
theme(axis.text=element_text(size = 10),
axis.title=element_text(size = 10),
text = element_text(size = 10),
axis.line = element_line(size = 0.25),
axis.ticks=element_line(size = 0.25),
panel.grid.major = element_blank(),
#panel.grid.minor = element_blank(),
panel.border = element_rect(colour = "black", fill = NA, size = 0.5),
panel.background = element_blank(),
legend.position = "top" ,
legend.direction = "vertical",
legend.title = element_blank(),
legend.text = element_text(size = 13),
legend.background = element_blank(),
legend.key = element_blank()) +
labs(x = '', y = '', title = "") +
theme(plot.title = element_text(size=10)) +
theme(strip.text.x = element_text(size = 8,color="black"),
strip.background = element_blank()) +
theme(strip.text.x = element_text(size = 8, colour = "black"))
My problem is the following:
when I create the legend, there is a separate legend for the colors and a separate one for the points.
How can I create a single legend for each of the 8 variables?
Let me minimise your code and focus on the legend issue. This is what you have now.
ggplot(b,aes(x = c, y = value, colour = variable, linetype = variable)) +
geom_line() +
geom_point(aes(shape = factor(variable)),size=1.7)
Your data frame, b has variable as factor. You use this in two ways here; variable and factor(variable). You can simply use variable for shape in geom_point; make all variable identical.
ggplot(b,aes(x = c, y = value, colour = variable, linetype = variable)) +
geom_line()+
geom_point(aes(shape = variable),size = 1.7)
I saw some warning messages related to colours and other things. You may want to take care of them. But, for legend, this is one way to go.
Take from the ideas on this page: http://www.cookbook-r.com/Graphs/Legends_(ggplot2)/#modifying-the-text-of-legend-titles-and-labels
I edited your code to make the data visible (you had problems with your x-axis limits. Note the final three lines. These commands tell ggplot to create only one legend.
a<-replicate(6,rnorm(100))
colnames(a)<-letters[1:6]
b<-melt(a,id.vars=1:1)
colnames(b)<-c("c","variable","value")
ggplot(b,aes(x=c,y=value,colour=variable,linetype=variable)) +
geom_line() + geom_point(aes(shape=factor(variable)),size=1.7)+
scale_x_continuous(limits=c(0,100))+
scale_y_continuous(limits=c(-2,2),breaks=seq(-2,2,0.1),expand=c(0.01,0.01))+
theme_bw(base_size=12, base_family="Helvetica") +
theme(axis.text=element_text(size=10),
axis.title=element_text(size=10),
text = element_text(size=10),
axis.line = element_line(size=0.25),
axis.ticks=element_line(size=0.25),
panel.grid.major = element_blank(),
#panel.grid.minor = element_blank(),
panel.border = element_rect(colour="black",fill=NA,size=0.5),
panel.background = element_blank(),
