Bug introduced in 11.0 and fixed in 11.1
The Callout
option is a new option for plotting, but the performance is very poor, see bellow testing case.
num = 1000;
list = N@Sin@Range[num];
list2 = ReplacePart[list,num->Callout[Last@list,Last@list]];
GraphicsRow[{ListLinePlot@list // Timing,
ListLinePlot@list2 // Timing}, ImageSize -> Large]
it spends more times running time when data plotting option Callout
is used. I just wonder why?
