Title: the concentration (molarity) vs time curve
Post by: sama.k on May 28, 2020, 02:57:34 PM
Hello;
Is the bellow script right for showing Na element concentration (mmol/l) versus time?
Many thanks

USER_GRAPH 9
    -axis_titles            "Time (days)" "Na  (mmol/l)" ""
    -chart_title            "Na concentration"
    -initial_solutions      false
    -connect_simulations    true
    -plot_concentration_vs  x
  -start
10 GRAPH_X total_time/86400
20 GRAPH_Y (TOT("Na")* TOT("WATER") / SOLN_VOL)*1000
  -end
    -active                 true

OR

USER_GRAPH 9
    -axis_titles            "Time (days)" "Na  (mmol/l)" ""
    -chart_title            "Na concentration"
    -initial_solutions      false
    -connect_simulations    true
    -plot_concentration_vs  x
  -start
10 GRAPH_X total_time/86400
20 GRAPH_Y (TOTMOLE("Na")/SOLN_VOL)*1000
  -end
    -active                 true
