Using Wt 3.2.2-p1:
If I plot data that has the constant value of 2000.0, with scale_ = LinearScale,
the assertion at the end of WAxis.C fails:
assert (segment.renderMinimum < segment.renderMaximum)
The problem appears to be in the calculation of 'resolution'.
if (scale_ == LinearScale)
resolution =1e3 * std::numeric_limits<double>::epsilon()
since resolution has the value 2.2204460492503131e-13, it is too small to add
or subtract to
segment.renderMinimum
or
segment.renderMaximum
to cause these two values to differ.
A fix that works for me is to calculate resolution based on the segment limits:
resolution = 1e-3 * segment.renderMinimum
