+'''
+This file gives the pressure trace for 2 traces (Nominally measured and simulated)
+but can be modified to do 1 or more if needed.
+
+It will automatically scale from -180 to 180 for a 2-Stroke
+
+It needs .txt files copied from the data of GT-Power with the format of:
+
+title line
+pressure    CAD
+pressure    CAD
+.           .
+.           .  
+.           .
+
+Other needed info: Max y value for the y axis
+
+**Will need to adjust colors, line type, etc.**
