Chart::addSeries function does not allow discrete columns

[chaoyonghan]

First of all, thanks a lot for this great project and your nice work. I'm trying to replace out dated QtXlsxWriter library in my project with QXlsx. One thing I noticed is that function Chart::addSeries only allow continuous columns. In my use case I need to always use the 1st column (time) as x-Axis and a few user selected (discrete) columns of data as the y-Axis. In the old QtXlsxWriter code, this is possible.

Of course it won't be a problem for me to add an overload function myself, but it would be great if this function can be considered in the future version of QXlsx.

Dear @chaoyonghan

Thanks for reporting. I will register this issue to an enhancement.

This project can have many differences from QtXlsxWriter. If there is a difference that is not in the functionality you want, it is not necessary to replace the library. QtXlsxWriter is a very good library.
