Plot different colored lines automatically

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.

The same task, four prompts

Plot the three data sets on the same graph, with each line a different color, so they are easy to distinguish for the weekly lab meeting.

Before I share this with the design team, plot these three stress-strain curves. Make sure each material's curve is a distinct color and that the legend clearly identifies which line belongs to which material, so they can quickly compare performance.

CDecide — diagnose the stuck momentI just plotted the three different simulation runs, and the default colors are so close I can…+
I'm trying to plot three simulation results, but the colors are too similar, and I'm worried about confusing the client.
I just plotted the three different simulation runs, and the default colors are so close I can barely tell them apart. I'm afraid the client will misunderstand the differences in performance during Friday's demo. I don't know if I should try to manually pick colors or if there's a better way to ensure high contrast. What's the best way to automatically get distinct colors for multiple lines, especially when I might add more later, so the client can clearly see the trends?

DBecome — change the patternI consistently spend too much time manually picking distinct line colors for my plots,…+
I frequently waste time manually adjusting line colors to make plots readable for my thesis advisor.
I consistently spend too much time manually picking distinct line colors for my plots, especially when I add new data series. My thesis advisor always points out when lines are indistinguishable. What habit could I change to automatically generate clearly differentiated line colors for my plots, ensuring readability without constant manual tweaking?

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.
