Abstract
Automated generation of graphical displays of industrial process data tags including three trend charts for each data tag. The displays include trend charts for the time-weighted average, the minimum value, and the maximum value over a predetermined time period. Altering the transparency of the trend charts for the minimum value and maximum value enables displaying data for multiple tags on a single chart.
Claims20
An automated graphical display generation system comprising:
- a display device;
- at least one processor;
- and
- one or more processor-executable instructions stored on at least one computer-readable storage medium of the automated graphical display generation system, said processor-executable instructions including instructions that, when executed by the at least one processor:
- receive a query time period selection via a query graphical user interface of the display device;
- retrieve a plurality of time-weighted average data values from an industrial process historian device communicatively coupled to the automated graphical display generation system via a communications network, each retrieved time-weighted average data value representing a time-weighted average of data values captured during each of a plurality of intervals of the query time period;
- retrieve a plurality of minimum data values from the industrial process historian device via the communications network, each retrieved minimum data value representing a minimum data value captured during each interval;
- retrieve a plurality of maximum data values from the industrial process historian device via the communications network, each retrieved maximum data value representing a maximum data value captured during each interval;
- and
- generate, in response to said retrieving the time-weighted average data values, the minimum data values, and the maximum data values, a graphical user interface on the display device comprising:
- a time-weighted average trend line for the retrieved time-weighted average data values;
- a minimum trend line for the retrieved minimum data values;
- and
- a maximum trend line for the retrieved maximum data values.
11 more elements
A computer-implemented method comprising:
- receiving a query time period via a graphical user interface of a display device;
- dividing the received query time period into intervals, wherein the number of intervals is dependent upon a display resolution of the display device;
- retrieving a time-weighted average data value for each interval from an industrial process historian device via a communications network, wherein each retrieved time-weighted average data value represents a time-weighted average of the data values captured during the interval;
- retrieving a minimum data value for each interval from the industrial process historian device via the communications network;
- retrieving a maximum data value for each interval from the industrial process historian device via the communications network;
- and
- generating a display on the display device in response to said retrieving the time-weighted average data values, the minimum data values, and the maximum data values, the display comprising:
- a time-weighted average trend chart for the retrieved time-weighted average data values;
- a minimum trend chart for the retrieved minimum data values;
- and
- a maximum trend chart for the retrieved maximum data values.

A computer readable storage device having processor readable instructions stored thereon including instructions that, when executed by a processor, implement a method of automatically generating a graphical display for time series data, comprising:
- receiving a query time period selection via a graphical user interface of a display device;
- receiving a first tag selection via the graphical user interface of the display device, wherein the first tag is one of a plurality of tags of an industrial process historian;
- receiving a second tag selection via the graphical user interface of the display device, wherein the second tag is one of the plurality of tags of the industrial process historian;
- dividing the received query time period into intervals, wherein the number of intervals is based upon a display resolution of the display device;
- retrieving a first time-weighted average data value for each interval from the industrial process historian via a communications network, each retrieved first time-weighted average data value representing a time-weighted average of the data values for the first tag captured during the interval;
- retrieving a first minimum data value for each interval from the industrial process historian via the communications network, each retrieved first minimum data value representing a minimum data value for the first tag captured during the interval;
- retrieving a first maximum data value for each interval from the industrial process historian via the communications network, each retrieved first maximum data value representing a maximum data value for the first tag captured during the interval;
- retrieving a second time-weighted average data value for each interval from the industrial process historian via the communications network, each retrieved second time-weighted average data value representing a time-weighted average of the data values for the second tag captured during the interval;
- retrieving a second minimum data value for each interval from the industrial process historian via the communications network, each retrieved second minimum data value representing a minimum data value for the second tag captured during the interval;
- retrieving a second maximum data value for each interval from the industrial process historian via the communications network, each retrieved second maximum data value representing a maximum data value for the second tag captured during the interval;
- and
- generating a graphical display on the display device in response to said retrieving the first time-weighted average data values, the first minimum data values, the first maximum data values, the second time-weighted average data values, the second minimum data values, and the second maximum data values, the graphical display comprising:
- a first time-weighted average trend chart for the retrieved first time-weighted average data values;
- a first minimum trend chart for the retrieved first minimum data values;
- a first maximum trend chart for the retrieved first maximum data values;
- a second time-weighted average trend chart for the retrieved second time-weighted average data values;
- a second minimum trend chart for the retrieved second minimum data values;
- and
- a second maximum trend chart for the retrieved second maximum data values;
- wherein the first time-weighted average trend chart, the first minimum trend chart, and the first maximum trend chart have a first color on the graphical display, and
- wherein the second time-weighted average trend chart, the second minimum trend chart, and the second maximum trend chart have a second color on the graphical display.
