Remove whitespace around figure's PDF output

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

Save the current figure to a PDF file named 'analysis_plot.pdf', and trim any extra whitespace around the plot so it fits cleanly into the presentation.

Before I send this plot to Dr. Evans for the grant proposal, make sure it looks professional. Save the current figure as a high-quality PDF, remove all unnecessary whitespace, and ensure the text and lines are crisp, not pixelated, so it reads well in print and on a tablet.

I've generated a complex plot for the final report.
I've generated a complex plot for the final report, and when I save it as a PDF, there's always a big white border that makes it look unprofessional in the document. I'm afraid if I crop it manually, I might lose some detail or make it inconsistent across figures. What's the best way to automatically remove that whitespace and ensure the plot fills the page area without distortion, so it's ready for the publisher?

My generated PDF figures always have too much whitespace, requiring manual cropping later.
My generated PDF figures always have too much whitespace, requiring manual cropping later, which wastes time and sometimes introduces inconsistencies. It's a recurring frustration when preparing papers and presentations. What habit should I change in my figure saving process to automatically produce tightly cropped, publication-ready PDFs without extra borders?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from MATLAB's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
