Howto plot a boxed label with a specific background color? (Like the legend box)

推荐答案

您的意思是:

LABEL="label in a box"
set obj 10 rect at 0,0 size char strlen(LABEL), char 1 fc rgb "cyan"
set label 10 LABEL at 0,0 front center
plot sin(x)

Here's a link to gnuplot's demo where I got the idea.

当然，您可以将盒子的尺寸稍大一些-我发现它使外观看起来更好:

Of course, you can make the size of the box slightly bigger -- I find that it makes things look a little nicer:

set obj 10 rect at 0,0 size char strlen(LABEL)+1, char 1.5 fc rgb "cyan"

但这取决于您.
