Storage medium to store data display control program, data display control method, and data display controller

A data display control method comprising:

• storing first data and second data, the first data being data related to a manufacturing device in operation, and being time series data for a period of time including a first date and time;
• causing the first data to be displayed in a first display area and, when a second date and time is designated within the first display area, causing a first marking position indicating the second date and time to be displayed in the first display area;
• registers registering first marking information related to the first marking position;
• causing the second data to be displayed in a second display area, reads the registered first marking information, and causing the first marking position indicating the second date and time to be displayed in the second display area;
• causing the second data to be displayed in the second display area, the second data being data on the manufacturing device in operation for a period of time including a third date and time and, when a fourth date and time is designated within the second display area, causing a second marking position indicating the fourth date and time to be displayed in the second display area;
• registering second marking information related to the second marking position;
• and
• reading the registered second marking information and causing the second marking position to be displayed in the first display area, wherein
• the first marking position and the second marking position are displayed in the first display area and the second display area, the first marking position and the second marking position being linked with each other.

A data display controller comprising:

• a memory to store first data and second data, the first data being data related to a manufacturing device in operation, and being time series data for a period of time including a first date and time;
• first display circuitry to cause the first data to be displayed in a first display area and, when a second date and time is designated within the first display area, cause a first marking position indicating the second date and time to be displayed in the first display area, the first display circuitry registering first marking information related to the first marking position, in the memory;
• and
• second display circuitry to cause the second data to be displayed in a second display area, read the first marking information from the memory, and cause the first marking position indicating the second date and time to be displayed in the second display area, wherein
• the second display circuitry causes the second data to be displayed in the second display area, the second data being data on the manufacturing device in operation for a period of time including a third date and time and, when a fourth date and time is designated within the second display area, causes a second marking position indicating the fourth date and time to be displayed in the second display area, the second display circuitry registering second marking information related to the second marking position, in the memory,
• the first display circuitry reads the second marking information from the memory and causes the second marking position to be displayed in the first display area, and
• the first display circuitry and the second display circuitry cause the first marking position and the second marking position to be displayed in the first display area and the second display area, the first marking position and the second marking position being linked with each other.
