Including initial concentration in USER_GRAPH output

[AzadGhadirian]

Hello all!

I am currently working on the visualization of my phreeqc results.
So I have modeled a pretreatment of a brackish water by adding NaOH and aerating the water with ambient air. The Goal is to precipiate CaCO3 and MgCO3. Later I will compare the results with other methods like aerating with Gas with higher CO2 content etc.

My problem is that the User Graph does not visualize the initial concentration of Ca and Mg but starts with the concentration after the first Reaction-step. The highest precipitation of Ca and Mg is in the first step so it is important to also show that.
I have researched the User Forum and different User Graph functions but couldn't find a solution yet...

I would be very greatful if someone has an idea how to fix this problem!
Thank you very much and all the best,
Azad

Oh yes, of course! Thank you very much!
