Wt

3.2.1, we can not use the 3.2.2 because the layout is totaly not working for our application.

This is the complete back trace:

so inspecting the variables I have:

(gdb) p segment.renderMinimum
$1 = 1997
(gdb) p segment.renderMaximum
$2 = 1997
(gdb) p scale_
$3 = Wt::Chart::LinearScale
(gdb) p segment
$4 = (const Wt::Chart::WAxis::Segment &) @0x7fcc540e33d0: {minimum = -1.7976931348623157e+308, maximum = 1.7976931348623157e+308, renderMinimum = 1997, 
  renderMaximum = 1997, renderLength = 1.7976931348623157e+308, renderStart = 1.7976931348623157e+308, dateTimeRenderUnit = 1970973440, 
  dateTimeRenderInterval = 32716}
(gdb) p AUTO_MINIMUM
$5 = -1.7976931348623157e+308
(gdb) p AUTO_MAXIMUM
$6 = 1.7976931348623157e+308
(gdb) p resolution_
$7 = 0

and that is the problem look at this indeed:

$ cat main33.cpp 
#include <cassert>
#include <limits>

int main() {
  double resolution = 1E3 * std::numeric_limits<double>::epsilon();

  double average = 1997;

  double max = average + resolution / 2;
  double min = average - resolution / 2;

  assert (min < max);
}
$ g++ main33.cpp
$ ./a.out 
a.out: main33.cpp:12: int main(): Assertion `min < max' failed.
Aborted (core dumped)

I will give it a shot and I'll let you know. The layout change have killed us, we are spending lot of time to dig into it, we are even paying users...

Koen,

I due the layout change we can not use the 3.2.3 yet, I have backported the WAxis.C from it to our 3.2.1, we had the assert failure again I was able to only find this:

segment.renderMinimum was 0

segment.renderMinimum was 0

resolution_ was 0

I'm going to instrument that method due the fact most variable have a scope already closed when the assert happen.

Hey Gaetano,

You may want to consider more changes to the whole Chart namespace to backport to 3.2.1 in that case ?

Regards,
