How do you adjust the line graph to avoid so much spare space?. Is scale alpha the way to trim the line graph?.
ggplot(cdata) +
geom_line(aes(x = Date, y = Value)) +

Does this answer your question? [set date range in ggplot](https://stackoverflow.com/questions/14162829/set-date-range-in-ggplot) – Paul May 09 '22 at 06:52

You can use the scale_x_* and scale_y_* family of functions in ggplot2 to control the scaling and limits of the axes.
Assuming your cdata$Date is a Date, you can do the following:
ggplot(cdata) +
geom_line(aes(x = Date, y = Value)) +
scale_x_date(limits = as.Date(c("2020-01-01", "2020-12-31")))
EDIT: If you are looking to scale the y axis, it is continuous, so you could use scale_y_continuous(). There are also other scaling functions available, like scale_*_discrete(), scale_*_log10(), and scale_*_reverse(), depending on the type of values on your axes.

and then for the y axis, you do something like scale_x_value(limit = as.Dbl(c("2e.00,))? – morgenphil May 08 '22 at 11:38

The y axis appears to be continuous, so you could use `scale_y_continuous()`. – Matthew Fisher MSCIS May 08 '22 at 11:42

so I tried scale_y_continous(limits = c(1e.05, 3e.00)) but it came up with an empty graph – morgenphil May 08 '22 at 11:51

You misspelled 'continuous' and have periods (.) instead of plus signs (+). Try: `scale_y_continuous(limits = c(1e+05, 3e+00))` – Matthew Fisher MSCIS May 08 '22 at 14:10
