Update axes in QLineSeries

[Eduardo Huerta]

I have a function that updates the X and Y ranges in real time and allows to visualize all the data of 5 QLineSeries. This function works correctly when I graph 5 QLineseries in a single window, but it works incorrectly when I add other QLineSeries in other windows (see image). I have observed that the X axis does not have this problem, but I suppose it is because the data in the X axis are the same in all the windows (I graphic in each window against time). My question is, how can I correctly update the Y axis of each window?

void setRange(QChart *mChart, qreal xValue, QVector<double> yValue)
This function receives the QChart of the window where the QLineSeries are plotted, the data of the X axis and a vector with the minimum and maximum value of the Y axis. I thought that with the QChart of each window it was enough to update the Y axis of each window , but I think that is not enough.
Thanks for help me.
