+% Template MATLAB code for visualizing correlated data using the
+% SCATTER function.
+
+% Prior to running this MATLAB code template, assign the channel variables.
+% Set 'readChannelID' to the channel ID of the channel to read from.
+% Also, assign the read field IDs to the variables 'fieldID1', 'fieldID2', and 'fieldID3'.
+
+% TODO - Replace the [] with channel ID to read data from:
+readChannelID = []];
+% TODO - Replace the [] with the Field ID to read data from:
+fieldID1 = 1;
+% TODO - Replace the [] with the Field ID to read data from:
+fieldID2 = 2;
+% TODO - Replace the [] with the Field ID to read data from:
+fieldID3 = 3;
