How edit the type of data at the x axisReturn to overview

I need a graphic whit the x axis show names, not number, for example in the y axis show hours of work and the x axis show name of employes. But qcustomplot only admit double for the both axis. Please someone explain me this dude. Sorry for my englihs I am from Cuba.

for the name axis, you would use

and for the hours axis, it depends on the format you want. doubles would be fine if you just set whole numbers?
there is also

I do this
QSharedPointer<QCPAxisTickerText> textTicker(new QCPAxisTickerText)

And return this error
undefined reference to QCPAxisTickerText::QCPAxisTickerText()

And I dont know why because I add all include
