Raw Data

Abstract

The Raw Data Chart panel displays a chart providing an analysis of one or multiple Signals using their raw values, as read directly from the Device.

This article describes the Raw Data chart available by clicking the dedicated tile. The Raw Data Chart is a high resolution chart providing an analysis of one or multiple Signals using their raw values, as read from the Device.

The Raw Data chart panel

The toolbar of the Raw Data chart panel allows the following selections:

  • selection of the Time frame using the Calendar button - the view is expanded to display the following time frame options:

    The Calendar view

    • Time range options - 1H (last hour), 8H (last 8 hours), 1T (last day), 1W (last week)

    • From / To selectors - allow a customised time frame selection, where the user can chose the Start and End date and time.

    Note

    After selecting the desired time frame the user must click the Apply button to preserve the selection.

  • selection of the Chart settings - the view is expanded to allow the user to manually input the desired maximal measurements to be considered by the chart.

    The default maximal value can be customised in the Panel parameters. Regardless of the default value defined by the system administrator, the user can increase / decrease the Maximal displayed measurements value, as desired.

    Note

    In case the maximal measurement value is lower than the actual plotted data, the result is cut and the user is notified.

  • selection of the Signal using the Open filters button - opens the Signal List panel where all the i4connected Signals are displayed.

    The user is allowed to select multiple Signals but the chart will only display the number of Signals that the system administrator defined as default, in the panel parameters. The selected entities are highlighted in red colour. To apply the selection to the chart the user needs to press the bottom Select button.

    Tip

    Signals that are currently used by the chart will no longer be visible in the Signal List panel.

    All the selected Signals are displayed as cards at the bottom of the chart providing information about the Signal name or alias name and the used unit of measure.

    When the maximum amount of Signals are selected and the limit is reached, the Open Filter button becomes inactive.

    The applied Signals can be removed by clicking the respective card. The chart will be automatically refreshed to bring the data up to date and the Open filter button is activated.

The Raw Data chart represents the data obtained from an intersection between the chosen Signal raw values. The Raw Data line chart uses two axes, as follows:

  • the vertical axis represents the value per unit.

    Note

    The vertical axis supports multiple units of measure, each being represented separately.

    Multiple vertical axes

  • the horizontal axis represents the selected measurement time-stamp.

    Note

    The horizontal axis is impacted if a more granular selection is applied, by pulling the cursors at the top of the time frame bar, acting like a zoom in and out action.

When multiple Signals are applied to the chart view, each Signal is represented with a different colour, hence making the chart easier to read.

Chart lines

By hovering the mouse cursor over the chart lines three tooltips are displayed, as follows:

  • the chart tooltip represents the highest peak of the hovered Signal;

  • the vertical axis tooltip represents the exact registered value for the hovered Signal;

  • the horizontal axis tooltip represents the exact time of the measurement, for the hovered Signal.

Under the chart view the legend of selected Signals is displayed. While hovering the mouse cursor over a legend label, the line trend of that Signal will be emphasised in the chart by dimming down the other trend lines.

The legend can also be used to toggle on or off the representation of Signals, by clicking on the legend labels of the corresponding Signals.
