Even though QXYSeries has a pointAdded() signal, it doesn't appear that the QChart listens for it. So once you initially set the series on the chart, that's it. AFAIK, the only way to implement real-time behavior is to remove the series from the chart, add the points to it, then add it back to the chart.

If there are several QXYSeries derived series added to the chart and no series of other types have been added, then only one pair of axes is created. If there are several series of different types added to the chart, then each series gets its own axes pair.

For example, on a chart having regional categories “West”, “East”, and “Mid-west”, a series might be “Q1 Sales” and have values 42, 120, and 34. The series in this case coheres around the first quarter time period. In general, the type (class) of a series object depends upon the chart type. pub unsafe fn append_2_double (&self, x: c_double, y: c_double) [src] [ −] Adds the data point with the coordinates x and y to the series.

A horizontal model mapper is used to create a connection between a line, spline, or scatter series and the data model that has X and Y rows for the coordinates and holds the data points for the XYSeries as columns.
