Plotting with different database in a phreeplot image

[Xavier.Qiu]

Hello everyone and happy new year!
I have a question:
Is it possible to plot an image to show the difference of 3 database, for example, in phreeplot, I want to plot the solubility of Uranium by using 3 different database, and I want to plot them in one image, is it possible to use <loop> or other operations to achieve this effect?

No, with PHREEQC and PhreeqcI, you can only use one database at a time. You would need to make three runs and then combine the three output files for your favorite plotting program.

If you know R, you could use the R version of PHREEQC in a script to do the three calculations, combine the data, and plot. It is also possible using the COM version of IPhreeqc with Matlab or Excel, or you can use IPhreeqc non-COM version to do the calculations under program control with C, Fortran, or C++. Python with PhreeqPy is also possible.
