Issue with streaming out histograms #396

Closed taehyounpark closed 3 months ago

taehyounpark commented 3 months ago

Hello,

I'd like to report a possible issue with the streaming feature of the histogram; following one of the examples to print out the histogram reports this compilation error from macOS homebrew's installation:

base ❯ brew list boost
/usr/local/Cellar/boost/1.82.0_1/include/boost/ (15673 files)
#include <boost/histogram.hpp>

int main() {

  using namespace boost::histogram;

  std::ostringstream os;

  // width of histogram can be set like this; if it is not set, the library attempts to
  // determine the terminal width and choses the histogram width accordingly
  os.width(78);

  auto h1 = make_histogram(axis::regular<>(5, -1.0, 1.0, "axis 1"));
  h1.at(0) = 2;
  h1.at(1) = 4;
  h1.at(2) = 3;
  h1.at(4) = 1;

  // 1D histograms are rendered as an ASCII drawing
  os << h1;
}

Indeed, apologies for my silly mistake and thank you for pointing it out :slightly_smiling_face:
