SPECIATION
calculationType species # Cd speciation as a function of pH - log c vs pH
calculationMethod 1
mainSpecies Cd
xmin -13.0 # range of logH
xmax -6.0
resolution 100
PLOT
plotTitle "log species concn vs pH<br>(using logspeciesvsph.inc)"
ytitle "log concentration (mol/kgw)"
labelSize 1.7 # controls the size of the key text
pxmax 13 # sets upper limit on x-axis
customXcolumn 2 # x-column is second column
legendTextSize 1.3 # reduce the size of the legend (key) text
extraText "extratextlogCdspeciation.dat" # places the legend inside the plot
CHEMISTRY
include 'logspeciesvsph.inc' # contains the logic for outputting the expected x-axis, y-axis (log c) pairs expected by 'species' plot type
