Running The Matrix Samples

AllSelected Sample

In the AllSelected sample, the Spotfire Streaming® Matrix operator is configured to create a list of tuples and output the list only when all the selected values change between the last input tuple and second-to-last input for all the selected fields, which in this sample are the Temperature and Voltage fields.

  1. In the Project Explorer view, open this sample's folder.

    Keep an eye on the bottom right status bar of the Studio window. Make sure any Updating, Downloading, Building, or Rebuild project messages finish before you proceed.

  4. Click the Run button. This opens the SB Test/Debug perspective and starts the module.

  5. In the Feed Simulations view, select the available feed simulation and click the Run button.

  6. In the Output Streams view, observe tuples emitted on the DataOut output stream.

  7. Press F9 or click the Stop Running Application button.
