Bug introduced in 11.0.0. Fixed in 11.1.0.

Why is it that:

Plot[{x^2}, {x, 0, 1}, PlotLegends -> {"a"}]

does fine, but:

funcs={x^2};
Plot[funcs, {x, 0, 1}, PlotLegends -> {"a"}]

makes the legend disappear?

Please note that clearly this is a toy example, so a workaround is not the issue here. I would like to understand what is going on. Is it related to what Plot[] looks for in its first argument? I know that funcs==={x^2}, so that is a list of functions of x, which it should be.

Thanx.

    $\begingroup$ It might be side effect due to the HoldAll property of Plot. Try Plot[Evaluate@funcs, {x, 0, 1}, PlotLegends -> {"a"}] $\endgroup$ – Nasser Jan 16 '17 at 23:41
  • $\begingroup$ I can't reproduce your result. If I run your code, the legend is drawn as expected. Which version of Mathematica do you use? $\endgroup$ – Felix Jan 17 '17 at 0:06
  • $\begingroup$ @Felix in version 11.0.1 the legend do indeed disappear. But adding Evaluate they show up. $\endgroup$ – Nasser Jan 17 '17 at 0:09

    $\begingroup$ That's remarkable, considering that they don't disappear in 11.0.0. I have updated to 11.0.1 and can confirm that they now do disappear. $\endgroup$ – Felix Jan 17 '17 at 1:44

    $\begingroup$ It's a bug. It's fixed in the upcoming release, and I'll update this once that's out the door. $\endgroup$ – rcollyer Mar 14 '17 at 14:39

On the upcoming release, this works fine.
