R help - Aug 2021 - Help needed with getting a decent image of ggplot2 graph

I am able to change but the place where I have to submit a similar graph has
kept a fixed upper limit of 440 pixels for the width and an upper limit of 300
for the dpi.

 Hi bharat,
I think there is a conflict between your image size and resolution.
You need a lot larger height and width in pixels to get 300 dpi
resolution for the whole plot.

 tiff("test.tiff", units = "px", width = 2200, height =
1250, res = 300)

would probably do it for you. How come you can't change the width and
height in pixels?

Ah, an _upper_ limit. Why not let tiff() work out the resolution
(res=NA - the default) and see if that passes muster.
