The Monitor Plot sits directly below the 3D Viewer within each Simulation tab, and plots the convergence history of a simulation. Use the dropdown menu at the top left of this panel to choose to display Residuals or other simulation outputs, if configured.

For steady state cases, the horizontal axis of the plots corresponds to the number of iterations. For transient cases, it corresponds to time steps. Small dotted vertical lines above the charts mark where intermediate solutions of the entire flow field were saved.

The longer vertical yellow line indicates which of these solutions is currently being displayed within the 3D Viewer itself. Additionally, above the plot, a box shows the iteration number of the currently selected solution.

You can move between saved solutions by clicking on the dotted lines, or by clicking the forwards and backwards arrows on the left of the box displaying the iteration number.

Hovering over the plot line will display values corresponding to intermediate iterations or time steps. You can also zoom in and out using the scroll wheel function on your mouse, and left-click and drag to pan the chart to the left or right.
