Defining worksheet's display item using spy.assets

[Kin How]

While building an asset tree using spy.assets, the display items of a worksheet can be defined under @Asset.Display(). The list below shows the options that can be set for each parameter of the display pane:

• Color: str = any valid color hex for example #4055a3, #068c45, #9d248f. 
• Line Style: str = {'Solid', 'Short Dash', 'Short Dash-Dot', 'Short Dash-Dot-Dot', 'Dot', 'Long Dash', 'Dash-Dot', 'Long Dash-Dot', 'Long Dash-Dot-Dot'} 

• Line Width: float = {1, 1.5, 2, 2.5, ...9.5, 10}
• Lane: int = {1, 2, ...}
• Samples Display: str = {'Line', 'Line and Sample', 'Samples', 'Bars'}

• Axis Auto Scale: bool
• Axis Align: str = {'Left', 'Right'}
• Axis Group: str = {'A', 'B', ...}
• Axis Max: float
• Axis Min: float

One example of display items set using @Asset.Display():

@Asset.Display()
def Bar_Graph (self, metadata, analysis):
    worksheet = analysis.worksheet('BarGraph')
    workstep = worksheet.workstep('BarGraph')
    workstep.display_items = [{
        "Item": self.Signal_1(),
        "Axis Group": "A",
        "Axis Auto Scale": True,
        "Lane": 1,
        "Line Style": "Solid",
        "Line Width": 10,
        "Samples Display": "Bars",
        "Color": "#4055A3"
    }, {
        "Item": self.self.Signal_2(),
        "Axis Group": "B",
        "Axis Auto Scale": True,
        "Lane": 1,
        "Line Style": "Short Dash",
        "Line Width": 1,
        "Samples Display": "Line",
        "Color": "#9D248F"
    }, {
        "Item": self.self.Signal_3(),
        "Axis Group": "B",
        "Axis Auto Scale": True,
        "Lane": 1,
        "Line Style": "Solid",
        "Line Width": 1,
        "Samples Display": "Line and Sample",
        "Color": "#CE561B"
    }, {
        "Item": self.self.Signal_4(),
        "Axis Group": "C",
        "Axis Auto Scale": False,
        "Axis Align": "Right",
        "Axis Max": 100.5,
        "Axis Min": 10,
        "Lane": 1,
        "Line Style": "Solid",
        "Line Width": 1,
        "Samples Display": "Samples",
        "Color": "#00A2DD"
    }]
    workstep.display_range = {'Start': '2020-06-11T00:00:00', 'End': '2020-07-12T00:00:00'}
    workstep.view = 'Trend'
    return workstep

Here is an example of Scatter plot push.

@Asset.Display()    
def Display(self,metadata,analysis):
        #define name of worksheet
        worksheet = analysis.worksheet(self.definition['Name']+' Scatter')
        #define name of workstep
        workstep = worksheet.workstep('Trends')
        # make sure workstep is in Scatter Plot view
        workstep.view = 'Scatter Plot'
        # define the display items - need to have at least the 2 signals you want in scatterplot
        workstep.display_items = [{
            'Item': self.Temperature(metadata)
        },{
            'Item': self.Relative_Humidity(metadata)
        }]
        # define the 2 scatterplot signals
        workstep.scatter_plot_series = {
            'X': {'ID': self.Temperature(metadata)},
            'Y': {'ID': self.Relative_Humidity(metadata)}
        }
        return workstep

    return workstep

 

There is a typo on the second item to the forth item of the workstep.display_items. The correct way to specify them is self.Signal() instead of self.self.Signal()

[RMC]

Is there any way to add labels to signals?  

[Sanman Mehta]

Unfortunately not.  It has been accepted in feature request. If you request via support@seeq.com we will make sure you get an email when it’s in product future release.

Btw, there is a workaround using fragile method I would not want to advertise here as well so feel free to reach out to Seeq support.

Can the above method be utilized to push a custom Python plot (for example, generated using python visualization libraries) to a WORKBENCH ?

I have seen some advanced topics covering how to push it to Organizer topics (requires HTML type but was wondering if it can be done to a workbench.

[Sanman Mehta]

Hi SBC,

This is not friendly to pushing visuals.  we can discuss more on our call later this week to discuss further.
