Description
QChart Y axis do not change when setting min & max values to numbers < 1.0E-12
I add one or more series to X& Y QValueAxis & use
axisY->setMin(_lowValue); axisY->setMax(_highValue);
as long as _highValue > _lowValue and the _lowValue > 1.0E-12
the chart responds as expected.
if either the setMin() or setMax() uses anything < 1.0E-12, the chart no longer responds.
To confirm that the chart is really getting these values, I use the
axisY->Min() & axisY->Max() gets and the values are present.
ie;
axisY->setMin(1.0E-12); axisY->setMax(1.0E-11);
works fine. If I use :
axisY->setMin(1.0E-14); axisY->setMax(1.0E-13);
the QChart does not respond.
