Add 'concMin' argument to plotConcHist()
Created by: emorway-usgs
There is a very subtle, seeming steady, possibly significant (statistically speaking) upward trend in pH (plot below). It is difficult to detect, however, because the y-axis lower limit defaults to 0. Would it be possible to add a concMin argument to plotConcHist(), kind of like what exists in plotConcQSmooth(eList, date1, date2, date3, qBottom, qTop, qUnit=1, printLegend=FALSE, concMin=7)
