Question about Plots

General Usage
1 
using SingularSpectrumAnalysis, Plots
# generate some data
L   = 20                      # Window length
K   = 100
N   = K*L;                    # number of datapoints
t   = 1:N;                    # Time vector
T   = 20;                     # period of main oscillation
y   = sin.(2pi/T*t);          # Signal
y .+= (0.5sin.(2pi/T*4*t)).^2 # Add another frequency
e   = 0.1randn(N);            # Add some noise
yn = y+e;
# plot(ys)

yt, ys = analyze(yn, L, robust=true) # trend and seasonal components
plot(yt, lab="Trend")
plot!(ys, lab="Season")

It’s generally not considered appropriate to tag package authors you find on GitHub when you post questions on Discourse - if you think there’s an actual issue with a package, file an issue on the GitHub repo.

You seem to be running into trouble with your GR backend. Run ] build GR and try again.
