What Is It? 
 The Accuracy Chart Wizard helps you evaluate the performance of mining models against test data from the mining structure, an Excel table, an Excel range, or an external data source. If the model to be evaluated is a classification model, then the wizard builds a lift chart that presents the model performance compared against a hypothetical ideal model (which performs classification without errors). If the model is an estimation model, then the wizard builds a scatter plot chart that presents the model estimations as well as the actual values from the test data. 

  What Does It Do? 
 The wizard helps you to choose a model to evaluate from the list of models available on the server, or a mining structure. If you choose a mining structure, then all models in the structure will be evaluated. You can also choose the output column of the models to be tested. In addition, you can choose the test data source: this can be test data from the mining structure, or a new data source. If you select new test data, the wizard enables you to define mappings between the test data columns and the model columns.
