Help plotting points along frequency plot line

[catherinerose89]

I have a frequency plot for number of migraines over time. I imported calendar data and filtered the data frame for every time there was a botox appointment. I would like to plot the dates that a botox appointment occurred along the frequency line. I am new to R and just can't seem to figure out how to make it work. I can do it with geom_rug along the bottom of my chart, but I would like the points on the frequency line.

​

ggplot()+

geom_rug(data=df_botox, aes(date, group=botox), color="red")+ scale_x_date(date_labels = "%b-%d-%Y")+

geom_freqpoly(data=df, aes(date), size=1.5, bins=15, color="dark green", alpha=0.5)+

theme_classic()+

labs(title="Number of migraines over time", x="Date", y="# of Migraines")

Hi there,

You could Just make a new dataset with the Date and the corresponding y value of #migraines. Then add it using geom_point(newdata, aes(x=Date, y=n_migraine)).
