How can I put data table under the X axis? And I would like it to be aligned to each tick according to the zoom in/out.

Do you mean using negative Y values? Just set the range of the Y axis to a +/-Value range like (-10, +10).
I'm afraid I don't completely understand what you mean, SK.
Do you want a table showing the data points as a list of numbers? In that case I'd suggest just using a Qt table widget below the QCustomPlot.
