How to add a label to a layer in QCustomplot?

[Muralidharan]

Hello all!
I would like to display the name of the plot in the top left corner of QCustomplot screen. I have added a layer to the QCustomplot using "addlayer" function. How to add a label to a layer to display the name or is there any other way to display a name in the QCustomplot screen?

thanks in advance.
