* This plot requires an observation coverage with feature points included that have observation data from the field. | |||
* This plot requires [[GMS:Automated Parameter Estimation#Sensitivity_Analysis|sensitivity data]] calculated as part of a MODFLOW simulation. | |||
* Selecting the correct dataset in the Project Explorer is essential to visualizing the results. If there is sensitivity data in the project, but the plot is not representing it, try selecting different solution datasets in the Project Explorer. The ''Sensitivity Plot'' display updates with each new selection, so it will become obvious which dataset must be active for the plot to accurately represent the data. Selecting the items under the ''Parameters'' folder in the Project Explorer does not draw the data in the plot. | |||

It may be used in transient simulations. This plot can display the mean error, mean absolute error, and root mean squared error between successive solutions and [[GMS:Observations#Point Observations|observed data]]. Various simulations would be run after changing model parameters, such as hydraulic conductivity or recharge. The plot will show trends in the solution to see if model parameter changes are causing better calibration with measured field data.

====Error vs. Simulation Troubleshooting==== | |||
If a plot will not generate or does not display significant data, it's possible that the conditions for the plot have not been set up correctly. To get a meaningful plot, take the following into account: | |||
* This plot requires data from multiple simulation runs for comparing to each other. | |||
: This data can be put in one project by using the '''Save As''' function to save the project with a new name before each MODFLOW simulation run. If the project isn't saved with a new name before each simulation run, the program will overwrite the former simulation results and the ''Error vs. Simulation'' plot will not have the desired comparison between simulation results. | |||
* This plot requires an observation coverage with feature points that include data from the field. This data is used to judge the accuracy of the each simulation run. If there is more than one observation coverage, ensure the correct observation coverage is selected on step 2 of the ''Plot Wizard''. | |||
* It's possible that the wrong geometry is active. Since simulation solutions are usually attached to geometries, it's important to select the geometry with the solutions to be compared. | |||

In addition, if transient calibration data has been defined, the plot can show time variant [[GMS:Calibration Targets|calibration targets]]. Only transient datasets may be used in these plots. Time series plots are created in the ''Plot Wizard'' by setting the ''Plot Type'' to "Time Series". A sample plot is shown in the figure. | ||

====Time Series Troubleshooting==== | |||
If a plot will not generate or does not display significant data, it's possible that the conditions for the plot have not been set up correctly. To get a meaningful plot, take the following into account: | |||
* This plot requires an observation coverage with feature points included that have observation data from the field. If there is more than one observation coverage, ensure the correct observation coverage is selected on step 2 of the ''Plot Wizard''. | |||
* A point from the observation coverage must be selected. This point can be selected in the Graphics Window or in the spreadsheet on the second page of the ''Plot Wizard''. If a point is not selected, the plot will not have significant results. | |||
* This plot requires a simulation with calculated transient data of the same type of data as the observation coverage (head, for example). If the simulation has not been run, then this plot will not have significant results. | |||
=== Active Dataset Time Series === | === Active Dataset Time Series === | ||
An Active Dataset Time Series plot is used to display the time variation of one or more scalar datasets associated to a given geometric element selected in a model solution. Active Dataset Time Series plots are created in the ''Plot Wizard'' by setting the ''Plot Type'' to "Active Dataset Time Series". | |||

If a plot will not generate or does not display significant data, it's possible that the conditions for the plot have not been set up correctly. To get a meaningful plot, take the following into account: | |||
* This plot needs a transient dataset interpolated to a mesh or a grid active in the Project Explorer and visible in the Graphics Window. This is usually a dataset associated with a model solution. | |||
* A specific element of the geometry must be selected in order to generate meaningful data in this plot. Grids require that a grid cell be selected. Meshes require that a mesh node be selected. | |||
