Results of sensitivity testing can be displayed in terms of histograms. These provide a cross section of values at a particular period in time. Histograms display the number of simulations for which the variable was in a given range at the specified time. Histograms provide a mechanism for seeing the distribution of values for a variable over all the simulations done and at a specified time. In Vensim PLE Plus the Bar tool 
is configured to show sensitivity at Special Time. For other configurations you can adjust the settings.
