Time Filtered Models

The second option for altering data in a pre-existing model is the restriction of the time axis in the Time Series Plots. Such restrictions, however, also alter between curve similarity values, making it necessary to re-compute the coordinates in the Scatterplot. Therefore, restricting the time axis values in the Time Series Plots requires the creation of a new, derived model. To create a time filtered derived model, select Create > Time Filtered Model, as shown in Figure 47. As with combined model creation, this must be done from within an existing model.

The time filtered model creation wizard consists of two dialogs. The first dialog is shown in Figure 48. In this dialog, simply adjust the sliders for a given time series plot to the desired range. After the desired restrictions have been performed, push the Continue button. To return the ranges to their full available values, push the Reset button.

As in the combined model wizard, the final dialog allows you to name and mark the new time filtered model. This is done in the same way that new models are named (see Name Model). After naming the model, an indicator and accompanying message box will be presented to show progress and any problems making the time filtered model (see Loading Data and Progress Indicators).
