Qt6 rejects Qt::OffsetFromUTC offsets beyond ±14h, so the old setUtcOffset(-m_startTime/1000) produced invalid QDateTimes and empty x-axis labels (zero extent -> collapsed axis). Replace the offset abuse with a TimeScaleDraw that shifts the label value, keeping data in absolute epoch and preserving pre-Qt6 behavior. Signed-off-by: andreidanila1 <andrei.danila@analog.com>
The label overlap loop in BasicScaleDraw::draw() removed ticks from a shrinking list, decimating down to ~1 label whenever wider (ARM fontconfig-substituted) fonts caused overlap. Replace it with stride-based decimation that keeps >=2 labels, guard against an empty scaleDiv, and stop half padding from collapsing to 0 for pixel-sized fonts (pointSize() == -1).
