Overview
In the OLI Studio, users often visualize simulation results through plots generated from Survey or Mixer calculations. These plots illustrate how chemical properties or species concentrations respond to varying input conditions such as temperature, pressure, or composition. Adjusting the plot variables, such as redefining the x-axis or selecting a different output property, can provide deeper insight into the system’s behavior.
This article outlines the procedure for modifying plot variables in OLI Studio.
Step-by-Step Instructions
- Open your plot.
- Press the Variables button.
- Select the variable(s) you want to appear in your plot and press >> to add the variable(s) to the X Axis, Y1 Axis, or Y2 Axis.
E.g., in the below example, the pH is added to the Y2 Axis. - Click OK to update the plot with the new variable settings. E.g., the pH is now shown on the second Y axis.
Notes
- You can create multiple plot templates from a single calculation.
- Output availability depends on the species present in the model and the type of calculation performed.
- Use the Units Manager (accessible via Tools > Units Manager) to ensure consistent and interpretable units across variables.
Conclusion
Modifying plot variables in OLI Studio enables users to tailor visual outputs for clearer interpretation of simulation results. Whether you're evaluating scaling potential, solubility behavior, redox conditions, or pH variation, adjusting the plot axes ensures that critical chemical trends are effectively visualized.
