How to change font and lollipop size? - r

Question

I want to increase the width of the sticks on my lollipop graph, and increase the size of the font of my y-labels. How would I go about doing that?
df_graph2 <- data.frame(
parameters = c("Cut back spending on food",
"Used up all or most saving",
'Increased credit card debt',
'Took money out of long-term savings',
'Borrowed money from family or friends',
'Pawned or sold possessions'),
values <- c(34.40,26.00,25.50,14.40,12.70,11.30))
df_graph2 %>%
ggplot() + aes(x=parameters, y=values) +
geom_segment( aes(x=parameters, xend=parameters, y=0, yend=values), color="gray82") +
geom_point( color="darkorange", size=4.2, alpha=0.9) +
geom_text(aes(label = paste(values,"%")), hjust = -.3,size=3.8,family="Arial") +
expand_limits(y = 100)+
theme_light() +
coord_flip() +
theme(
plot.margin = margin(1, 1, 4, 1.1, "cm"),
panel.grid.major.y = element_blank(),
axis.text.y = element_text(color = 'black'),
panel.border = element_blank(),
axis.ticks.y = element_blank(),
axis.ticks.x = element_blank(),
axis.title.x = element_blank(),
axis.title.y = element_blank(),
axis.text.x = element_blank(),
panel.grid.major.x = element_blank(),
panel.grid.minor.x = element_blank()
)

Change the y axis label size using the size parameter inside the element_text call of theme(axis.text.y and change the line width of the lollipops with size = inside geom_segment
ggplot(df_graph2, aes(parameters, values)) +
geom_segment(aes(xend = parameters, y = 0, yend = values),
size = 2, color = "gray82") +
geom_point(color = "darkorange", size = 4.2, alpha = 0.9) +
geom_text(aes(label = paste(values,"%")), hjust = -.3, size=3.8) +
expand_limits(y = 100) +
coord_flip() +
theme_void() +
theme(plot.margin = margin(1, 1, 4, 1.1, "cm"),
axis.text.y = element_text(color = 'black', size = 12, hjust = 1))
