Abstract
A display apparatus includes: an operation input device configured to designate a data range of an observed value; an analysis condition setting device configured to determine an analysis range or an analysis parameter of the observed value, corresponding to the number of samples included in the data range; a computation device configured to analyze a waveform or a trend of the observed value on the basis of the analysis range or analysis parameter; and a display screen generation device configured to cause a display device to display a waveform or a straight line as a computation result of the computation device.
Claims12
A display apparatus comprising:
- an operation input device that receives an operation signal, and designates a display range of an observed value with coordinates specified by the operation signal;
- an analysis condition setting device that determines, as an analysis range or an analysis parameter of the observed value, a predetermined proportion, that ranges from 5% to 20%, of a number of samples included in the display range, wherein the larger the display range, the larger the predetermined proportion;
- a computation device that analyzes a waveform or a trend of the observed value based on the analysis range or the analysis parameter;
- and
- a display screen generation device that causes a display device to display a waveform or a straight line as a computation result of the computation device.
A display method using a display apparatus, the method comprising:
- receiving an operation signal, and designating a display range of an observed value with coordinates specified by the operation signal;
- setting, as an analysis range or an analysis parameter of the observed value, a predetermined proportion, that ranges from 5% to 20%, of a number of samples included in the display range, wherein the larger the display range, the larger the predetermined proportion;
- analyzing a waveform or a trend of the observed value based on the analysis range or the analysis parameter;
- and
- displaying a waveform or a straight line as a computation result of the computation step.
A non-transitory computer-readable recording medium recording a program for causing a computer included in a display apparatus to execute:
- receiving an operation signal, and designating a display range of an observed value with coordinates specified by the operation signal;
- determining, as an analysis range or an analysis parameter of the observed value, a predetermined proportion, that ranges from 5% to 20%, of a number of samples included in the display range, wherein the larger the predetermined proportion;
- analyzing a waveform or a trend of the observed value based on the analysis range or the analysis parameter;
- and
- causing a display device to display a waveform or a straight line as a computation result of the computation command.
