The EQuIS Live - Historical Chart widget provides visual interaction with a high volume of data over an extended period of time. Remarks and qualifiers can be displayed on the widget. Users with editor permissions to the dashboard and the widget can add, edit, and delete remarks and qualifiers.
The widget contains two parts: A legend and a chart.
Legend
The legend displays information about the plotted series and allows the user to show or hide the series on the chart. The name of each series and logger source are denoted. If the series has a value for DT_LOGGER_SERIES.SERIES_UNIT, the series unit is displayed in parentheses.
Toggle the Show check box for each series to show or hide that series on the chart. The Nav column decides which series will be shown in the Navigator at the bottom of the chart. Click the series name in the legend to show or hide the typical range for the given series (the "plot band"). This range is defined in DT_LOGGER_SERIES.TYPICAL_MIN_VALUE and DT_LOGGER_SERIES.TYPICAL_MAX_VALUE, but can also be set manually for each series in the Widget Editor.
Note: Any series with longer description values may not get the full value displayed in the widget legend or the legend of an exported chart. |

Chart
The chart portion of the widget displays the logger data as a time series graph. The header of the chart contains a Chart Context Menu and navigation options. The user can hover over individual data points in the data series to see values. Remarks and qualifiers can be added to the chart.
Chart Navigation
The chart can be navigated by a variety of options:
•Using Zoom options (one day's worth of data, one week's etc.);
•Entering start and end dates and time;
•Using the Navigator; or
•Selecting a region of the chart to zoom in.
The Zoom buttons (top-left corner of chart) allow the user to quickly and easily zoom into a particular date range as follows:
•1d – One day
•1w – One week
•1m – One month
•1y – One year
•All – All of the data included in the widget
The dates to the right of the Zoom buttons (i.e., From and To) display the currently visible date range. For example, the series may have data from an entire year, but the user may be zoomed in to just two months. The From and To dates will display the start and end date of the time period that is currently visible on the chart.
If enabled in the widget properties, the chart Navigator will appear at the bottom of the chart. The Nav column decides which series will be shown in the chart Navigator. Use the Navigator to navigate the date range that is displayed within the chart. The Navigator shows the entire date range for the chart, with the currently visible date range selected as shown in the scroll bar. Use the bottom scroll bar to scroll through the date range. Click and drag the selected range to increase or decrease the visible date range.
Tooltip
Hovering the mouse over the chart will display a tooltip. The top line of the tooltip contains the date/time value at the current point on the time axis (i.e., X-axis). The date/time will be displayed based on the culture specified in the current browser settings. Following the date/time value, each logger name and series will be listed (assuming the series has a value for the current date/time). The series name will be followed by the value. The values will be displayed with the number format based on the culture specified in the current browser settings.
Chart Context Menu
Options for downloading data (as seen in the chart), printing or exporting chart images, and applying remarks or qualifiers can be found from the Chart Context Menu (
) in the top-right corner of the chart. The Chart Context Menu allows the user to:
•Download – When selected, the download options are displayed (defined below).

•Search – User can search qualifiers and remarks between date range. Users with editor permissions can edit or delete remark from list that will refresh on chart.

Remarks
Remarks allows a flag to be added on the data at a certain point to indicate an anomaly or to distinguish that data area in any way desired. Users with editor permissions to the dashboard and the widget can add, edit, and delete remarks. Clicking on a remark displays a dialog that allows user to edit or delete the remark. Use the Search functionality in the Chart Context Menu to find specific remarks.

Qualifiers
Qualifiers can be used to highlight specific portions of data via a selected color. If a 'transparent' color is selected, then this can be used to hide sections of data, if desired (e.g., if a logger was found to be faulty for a certain period). Users with editor permissions to the dashboard and the widget can add, edit, and delete qualifiers.

5.On the Date Range tab, adjust the start and end date times for the qualifier if needed.
6.On the Series tab, choose which series to apply the qualifier. If a series is charted more than once (e.g., Daily Max and Hourly Average), they will be grouped together. A grouped series will be selected by default if one or more are displayed on the chart.
7.Click OK. The chart will reload with the qualifier applied.
