The Axis do not match with the serie

[Alfacu]

Hi every Qt collage! I hope all be fine!

Ok, I have a problem. I trying to plot a data (no important date: the data come from Arduino), and all is fine but, the the axis values do not math whit the series values.

I tried some possibility.
1.

lineserie->append(count, value_a);
chart->removeSeries(lineserie);       //to remove the before serie and add the new one
chart->addSeries(lineserie);
chart->addAxis(axisX, Qt::AlignBottom);
chart->addAxis(axisY, Qt::AlignLeft);
lineserie->attachAxis(axisX);
lineserie->attachAxis(axisY);

Should be work I think... using the attachAxis() function, I suppose that the axes refresh it sealf and/or the line inside the chart. But that do not happen!!!

2. In the second try I refresh manually the values of the
   where count is the current data received ... I put tha range 10:34 (temperature)

lineserie->append(count, value_a);
chart->removeSeries(lineserie);         //to remove the before serie and add the new one
axisX->setRange(0, count);
axisY->setRange(10,34);
chart->addSeries(lineserie);

As you can see, there is a "non-connection" of the serie whit the axes and/or vie versa.

The best.
