Abstract
A self-centered zoom system includes a display device to indicate a measured quantity, and first and second bar graphs displayed on the display device. The first bar graph displays both a current value and a peak value of the measured quantity. The second bar graph displays an automatically zoomed range generally centered about one of the peak value, the current value, and a point lying between the peak and current values of the measured quantity.
Claims32
A system comprising:
- a display device to indicate a measured quantity;
- and
- first and second bar graphs displayed on the display device, the first bar graph to display both a current value and a peak value of the measured quantity, the second bar graph to display an automatically zoomed range generally centered about one of the peak value, the current value, and a point lying between the peak and current values of the measured quantity.
A system comprising:
- a display device to indicate a measured quantity;
- a bar graph displayed on the display device to display the measured quantity;
- and
- a strip chart to display a zoomed range of the measured quantity and a plurality of historical peak values of the measured quantity, wherein a furthest extremum value of the measured quantity is used to automatically rescale the strip chart so that the zoomed range is bounded by the furthest extremum value.
A system comprising:
- a display device to indicate a measured quantity, the measured quantity varying over time and including minimum and maximum peak values over a time period;
- a bar graph displayed on the display device to display the measured quantity in real-time;
- and
- a strip chart to display the minimum peak average value and the maximum peak average value of a user-defined number of samples of the measured quantity.
A method for displaying a zoomable bar graph, the method comprising:
- accepting a first user option to choose from one or both of the maximum and minimum peak values of a measured quantity;
- in response to the first user option, displaying the user selection on a first bar graph together with the measured quantity;
- accepting a second user option to auto-zoom the first bar graph;
- in response to the second user option, providing a second bar graph in which to display an automatically zoomed range of the measured quantity;
- and
- translating the measurements taken of the measured quantity to a scale required for display on the first and second bar graphs.
A method for displaying a zoomable strip chart, the method comprising:
- accepting a first user option to select a zoomed range of a measured quantity;
- and
- in response to the first user option:
- recording a furthest extremum value of the measured quantity over a time period;
- and
- displaying a plurality of peak values of the measured quantity on the strip chart, wherein the furthest extremum value is used to automatically rescale the strip chart, providing for at least one bound of the zoomed range.
A method for displaying a statistical strip chart, the method comprising:
- accepting a first user option to average a measured quantity;
- and
- in response to the first user option:
- calculating the average of a plurality of maximum and minimum historical peak values of the measured quantity at a sample number rate, wherein a data set having a calculated maximum peak value and a calculated minimum peak value is generated for each sample;
- and
- displaying each data set along a strip chart scale, wherein the scale is determined by the sample number rate.
