An issue to install st_viewer

[sqsun]

I got the error message when I did "make -j4" step:

~/libpath/st_viewer/src/analysis/AnalysisClustering.cpp:266:32: error: ‘QtCharts::QAbstractAxis* QtCharts::QChart::axisY(QtCharts::QAbstractSeries*) const’ is deprecated [-Werror=deprecated-declarations]
m_ui->plot->chart()->axisY()->setRange(min_y - 1, max_y + 1);

I ran into this issue today while installing STViewer on a fresh install of Ubuntu 18.04 and QT Version 5.12.0.

After reading the installation documentation, I removed QT, and installed version 5.9.2 (matching the documentation). I also ensured that I clicked the arrow in the QT Installation Tool and selected QT Charts.

I hope this helps solve this specific problem!
