GRAPH DISPLAYING DEVICE
First Claim
1. A graph displaying device comprising:
- a trend graph display that defines a first axis as a time axis to indicate time marks, defines a second axis that is perpendicular to the first axis as a data axis to indicate data values, and plots time series data in an orthogonal plane indicated by the first axis and the second axis, to display the plotted time series data as a trend graph;
a focus data pointer display that displays, as a focus data pointer, a pointer to indicate a plot point relative to a selectively indicated plot point of the time series data when a desired plot point of the time series data has been selectively indicated on the trend graph;
a focus data pointer moving/stopping unit that receives an instruction from an operator for starting movement of the focus data pointer in a designated earlier or later direction on the first axis, moves the focus data pointer in the earlier or later direction, designated by the instruction on the first axis, and stops, at a plot point of the time series data on the trend graph, the focus data pointer that has been moved; and
a numeric value information display that displays as numeric value information a data value and a time mark at the plot point of the time series data indicated by the focus data pointer.

Abstract
A graph displaying device includes a trend graph display that defines a time axis and a data value axis, and plots time series data in an orthogonal plane indicated by the axes to display a trend graph, a focus data pointer display that displays a pointer indicating a plot point relative to a selectively indicated plot point of the time series data when a desired plot point of the time series data has been selectively indicated on the trend graph, a focus data pointer moving/stopping unit that moves the pointer in a designated earlier or later direction on the time axis, and stops, at a plot point of the time series data, the pointer that has been moved, and a numeric value information display that displays a data value and a time mark at the plot point of the time series data.
