BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller of injection molding machine, an injection molding machine, and a recording medium. 2. Description of the Related Art Various sensors have conventionally been installed in injection molding machines. Therefore, in injection molding machines, a technique has been proposed to display various processes during injection molding based on detection signals from sensors or to display waveform data representing settings made by a user, on a display device.
