Description

list[float]

getGraphData( name )

Read the data of graphs.

loadHistoryTrend( trendsetName,

 syear, smonth, sday, shour, sminute,

 eyear, emonth, eday, ehour, eminute,

 step )

Read the past trend and display it on the widget.

loadTrend( trendsetName )

Read the trend group and display it as the real time trend.

  loadHistoryTrend( trendsetName:Trend set name,

                          syear:Start year, smonth:Start month, sday:Start day, shour:Start hour, sminute:Start minute,

                          eyear:End year, emonth:End month, eday:End day, ehour:End hour, eminute:End minute,

                          step=0:Display interval(Second)  )

  Read the selected data on the trend set by entering the start date and the end date.

        ㆍ trendsetName setting is as follows.

                - When loading the entire data : 'Trend set name'

                - When loading a subset of data : {'Trend set name' : ['Point 1', ' Point 2']}

                - When loading the data from two different trend set : ['Point 1', 'Point 2']

  Select the displaying space on the last parameter.

  If you did not set the last parameter, it displays it according to the recording period set on the trend set.

  Example) When loading the entire data

       chart = canvas.getObject('trend')  # Obtain the trend widget.

       # Display all data for 5 minutes interval.

       chart.loadHistoryTrend( 'Power', 2017, 7, 3, 1, 0, 2017, 7, 3, 2, 0, 60*5 )

  Example) When loading a subset of data

       chart = canvas.getObject('trend')  # Obtain the trend widget.

       # Display all data for 5 minutes interval.

       chart.loadHistoryTrend( trendSetName , 2017,7,3,1,0   , 2017,7,3,2,0 , 60*5 )

  Example) When loading the data from two different trend set

       chart = canvas.getObject('trend')  # Obtain the trend widget.

       # Display all data for 5 minutes interval.

       chart.loadHistoryTrend( trendSetName , 2017,7,3,1,0   , 2017,7,3,2,0 , 60*5 )

  Read the data printed on the graph.

        ㆍ name : Enter the name of graphs set on the history data chart widget.

  Example)

       chart = canvas.getObject('trend')  # Obtain the trend widget.

       print chart.getGraphData('Outlet')

  loadTrend( trendsetName:Trend set name )

  Read the data of the entered trend set and display it as the real time trend.

        ㆍ trendsetName setting is as follows.

                - When loading the entire data : 'Trend set name'

                - When loading a subset of data : {'Trend set name' : ['Point 1', 'Point 2'] }

                - When loading the data from two different trend set : ['Point 1', 'Point 2']

  Example) When loading the entire data

       chart = canvas.getObject('trend')  # Obtain the trend widget.

       data = chart.loadTrendSet('Available Power')   # Read 'Available Power' trend cell.

  Example) When loading a subset of data

       chart = canvas.getObject('trend')  # Obtain the trend widget.

       name = {'Available Power' : ['Equipment1.Power', 'Equipment2.Power']}

       data = chart.loadTrendSet(name)   # Read 'Equipment1.Power', 'Equipment2.Power' from 'Available Power'.

  Example) When loading the data from two different trend set

       chart = canvas.getObject('trend')  # Obtain the trend widget

       name = ['Equipment1.Power', 'Equipment2.Power']
