So I have a dataset that I am trying to plot and everything shows up except my data. The plot itself is made with the correct parameters I want excpet my data isn't there. My data table is listed below. And a photo of what running this code gives me.

And the code I used is this...

ggplot(Ecology_Project_Data, aes(x = Ecology_Project_Data$`Zebra Mussel growth rate (dN/dt)`, y = Ecology_Project_Data$`Salmon Growth rate (dN/dt)` )) +
+   labs(x = "Zebra Mussel Growth Rate (dN/dt)", y = "King Salmon Growth Rate (dN/dt)" , title = "Growth Rate of King Salmon Realtive to Zebra Mussel Growth Rate (Lake Michigan 1992-2018)")

What you're missing is a geom_* call.

If you use ggplot2, you need to add a call to geom_line, or geom_point, or one of the many other options. In the first call to ggplot functions, you're registering the variables you want to use. Then in these geom_* calls, yoou'll actually plot the data in the way you want.

Hope this helps.
