Plotting R in Jupyter lab with dark theme is barel

问题:

I am trying to plot using R kernel in Jupyter lab, and I set my Jupyter lab theme as "Jupyterlab dark."

Below is my code:

options(repr.plot.width=20, repr.plot.height=5)
plot(x)
points(x2,pch=1,col="blue")

This is what I get

Is there a way to make it look more like the plot below? (I switched jupyter lab theme to light, and now the plot is visible)
