Thanks for your note and feedback!

Dear GWB community, I would like to plot SI for mineral saturation, rather than (Q/K). My GSS spreadsheet is showing log (Q/K), but when I do an XY plot with "mineral saturation", Gtplot always uses (Q/K) rather than log (Q/K). If I switch the scale to log, it does not transform the data, only the axis scale. How can I plot SI (log (Q/K)) directly for mineral saturation using Gtplot? I found a work-around by copy/pasting the log (Q/K) column calculated by GSS into a new user-defined analyte, but it would be better if SI could be plotted directly. Thank you for your time and consideration. Andy
