Hi,
I created external legend without calling insertLegend() in my project which is based on Qwt 6.1.
I know I can use insertLegend(NULL) to delete the legend whose position is Top/Bottom/Left/Right. But it didn't work for hide the externl legend that I created.
I created my external legend by creating a new QwtLegend().
Does anyone know how to hide this kind of the external legend ?
Thanks!
