MERLIN-Expo

The charts screen allows you to plot simulation results and has a lot in common with the tables screen.

Depending on the type of simulation that has been run, different charts are available. A chart is created by first selecting outputs in the list. The will attempt to create a chart which suites the selected output, but if you want a specific chart you can select the chart type from the menu.

To the left is a list with all available simulation outputs. All results from a simulation is (by default) packaged in a folder named with the date and type of simulation ¹⁾. This folder in turn contains folders for each sub-system. These folders contains the simulation outputs.

If an output has dependencies - for instance a concentration which is contaminant dependent - lists will appear below where you can select which indices indices/contaminants you want to include in your chart.

¹⁾ If several simulations have been run using scenarios, the results for each scenario is packaged in a folder with the same name as the scenario.

When a result is selected a chart is automatically created. If you wish to create another type of chart or table, right-click and choose the type you want from the menu. To include more than one result in the same plot, keep the CTRL key pressed while selecting results.

Please refer to this page for more information about results.

Right-click a simulation output in the result list for a menu. The first half of the menu lets you create different types of charts and/or tables, the second half lets you manage results:

A time chart will plot the selected outputs against time. When you plot a probabilistic output, by default the mean value is displayed. To select other statistics you must edit the chart.

The scatter chart plots one or more outputs against another output. For deterministic simulations, values for all time points are plotted. For probabilistic simulations, values for a given time point are plotted. For more settings, edit the chart.

Displays a histogram for the selected outputs at a given time point. To control the number of bins and other settings, edit the chart.

The tornado chart is used for sensitivity analysis. It displays the impact of uncertain parameters on one output by displaying correlation coefficients in a horizontal bar diagram. You can select which sensitivity indices to display from the Plot box below. To specify which parameters to include, as well as other settings, edit the chart.|

Use the search filters below when the number of outputs make results difficult to find.

• Name - Enter part of the name of the output
• Type - The type of block used in the model for the output.

Each chart is given a page identified by the title of the chart. To change the properties of the chart, you can either use the buttons beneath in the Plot box, or right-click the chart and select Edit from the menu.

Archives can be created by right-clicking the list with simulation results.

You can also export data for a given chart either to an Excel file. Right-click the chart and select Export data….
