Opening a PDF in Illustrator cuts off an image

Hi all. I made a graph in R and exported that plot in PDF format. The colors in the PDF go beyond the "40000" mark at the bottom. However, when I opened the filed with Adobe Illustrator 2024, the graph is partially cut off (it doesn't even reach 40000). Any idea as to why this is happening? Thank you.

Are the lines in the graph a single connected path? If so, it's possible the path may have so many anchor points that a portion of the path is being disregarded. I think 32,000 is the maximum number of anchor points a path can have in Illustrator.

Thanks for clarifying, Bobby!

You've reached the limit as to how many points can be in path in Illustrator (approx 32000). There is no solution unless you simplify the graph at the source.

This was covered here a few times, most recently with somone creating a graph in Cairo. I don't know anything about either Cairo or R, but a quick google search mentions this being a problem and that there are apprently routines you can invoke to simplify the sampling in your graph, or by splitting your graph into a few separate sections at a time so you have a few lines that you can butt up against each other. The other way, of course, is to render your graph as a high-resolution image file in Photoshop.
