#include <sbknumpycheck.h> #include <qtgraphs_helper.h> Populates the data from a 2 dimensional numpy array containing the y values for a range starting a ``x``, ``z`` with steps of ``deltaX``, ``deltaZ``, respectively. Adds the list of data points specified by two one-dimensional, equally sized numpy arrays representing the x, y values, respectively. Replaces the current points with the points specified by two one-dimensional, equally sized numpy arrays representing the x, y values, respectively.
