This is a project I have done in college. Graph 1 shows an Excel sheet that contains lots of alarm data. These data were retrieved from sensors on a factory equipment. Graph 2 is called High Density Alarm Plot. It shows the density of alarms during a specified period (the redder the denser). It also reveals some relationships between different alarms. Graph3 is called Alarm Similarity Color Map. It shows the correlational relationships between two alarms. When the color is darker, it means that the two alarms are more likely to happen at the same period.
