\"P2_RGB<\/p>\n

P2 Explorer 4.5 addresses the need for users to build their own Explorer pages and trends. With the addition of two critical components, the Performance Curve and the Embedded Trend, Studio\u2019s Toolbox has a comprehensive set of controls, enabling you to create the pages that you need, in order to optimise the way you display your data.<\/p>\n

Explorer 4.5 offers a more usable Design Mode, and a Display Mode that makes it simpler for users to navigate through the displays, and easier to understand data and trends.\u00a0Navigation has been streamlined to give a better user experience, allowing users to link to pages, trends or related information on external URLs through hyperlinks or drill-down charts on pages, as well as view a trend or point details of data displayed on pages. Workspaces are easier to work with than before, and the ribbon tabs have been consolidated.<\/p>\n

Patch Release 4.5.3 has several new features, including dual hairline statistics, editing a calculation from the trend, and data error handling. There are also several enhancements to existing components, most notably the performance curve. Several issues raised against earlier releases have been resolved in this release.<\/p>\n

\n

Dual Hairline Statistics on Trend\u2019s Trace Table<\/h2>\n

The Trend\u2019s Trace Table has had a change to its Value column. In previous versions of Explorer, the Value column displayed the values for the respective items in the trace window. If the trend had hairlines, then this was the value from the latest hairline that was added or moved; otherwise, it was the value from the end-time of the selected time range for the trend.<\/p>\n

\"\"<\/a><\/p>\n

In this version of Explorer, there is still a Value column for the None<\/em>, Single<\/em>, or Multiple<\/em> hairline modes. However, this column changes to a drop-down list of Dual Hairline Statistics<\/em> options, if the trend is in Dual<\/em> hairline mode, and if two hairlines are selected.<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/p>\n

To enable the feature, you need to select two hairlines:<\/p>\n

\"\"<\/a><\/p>\n

The available options for Dual Hairline Statistics<\/em> are:<\/p>\n\n\n\n\n\n\n\n\n
Time Weighted Average<\/strong><\/td>\nThe time weighted average calculated from the data between the two hairline positions<\/td>\n<\/tr>\n
Value Difference<\/strong>
\n (previously shown in the Hairline Information Panel)<\/em><\/td>\n		The absolute value difference calculated from the values at the two hairline positions<\/td>\n<\/tr>\n
Time Difference<\/strong><\/td>\nThe time difference between the two hairline positions<\/td>\n<\/tr>\n
Standard Deviation<\/strong><\/td>\nThe standard deviation calculated from the data between the two hairline positions<\/td>\n<\/tr>\n
Min<\/strong><\/td>\nThe minimum value in the data range defined by the two hairlines<\/td>\n<\/tr>\n
Max<\/strong><\/td>\nThe maximum value in the data range defined by the two hairlines<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Note: The values in the trace table are calculated using the last known value before each hairline position, whereas the hairline information panel shows the interpolated value at the hairline position.<\/p>\n

Editing a Calculation from the Trend<\/h2>\n

In this version of Explorer, you can now edit a calculation or its description from the trend, where previously you could only save a new calculation.<\/p>\n

To edit a calculation from the trend, or save to a new calculation, click the corresponding calculator icon in the trace table.<\/p>\n

\"\"<\/a><\/p>\n

The Calculation Editor opens, to show the calculation.<\/p>\n

\"\"<\/a><\/p>\n

    \n
  1. To edit the calculation\u2019s description, click the pencil icon next to the description, then update the contents of the description edit box which appears below the calculation name.
    \n     \"\"<\/a><\/li>\n
  2. Edit the calculation expression in the expression edit box.<\/li>\n
  3. If you edit the calculation or its description, you have the option to save the changes to the existing calculation (click Save<\/strong>), save the changes to a new calculation (click Save<\/strong> As<\/strong>), or click Cancel<\/strong> to exit the calculation editor.<\/li>\n<\/ol>\n

    \"\"<\/a><\/p>\n

    If you cancel, and there are unsaved changes, a confirmation dialog gives you an opportunity to still save the change.<\/p>\n

    \"\"<\/a><\/p>\n

    Click Save<\/strong> to save your changes, Discard<\/strong> to discard changes, or Cancel<\/strong> to return to the calculation editor, which still has your unsaved changes.<\/p>\n

    You can save the unchanged calculation to a new calculation, by clicking the Save As<\/strong> button. This opens a dialog for the new calculation\u2019s Name<\/strong> and Description<\/strong>.<\/p>\n

     <\/p>\n

    \n

    Trend Trace Table Splitter<\/h2>\n

    In the Trend, you can now manually adjust the height of the Trace Table. Click the splitter at the top of the trace table, then drag it up or down to increase\/decrease the trace table height.<\/p>\n

    \"\"<\/a><\/p>\n

    \n

    Trend\u2019s Export to CSV Format<\/h2>\n

    The Export CSV<\/strong> function for a trend has changed so that the spreadsheet no longer shows columns for data errors or data confidence.<\/p>\n

    The data timestamps are now in a format that Microsoft Excel recognises, whereas previously they were exported in GMT.\u00a0This feature addresses customer requests SF371506 and SF373708.<\/p>\n

    \n

    Data Error Handling<\/h2>\n

    Explorer now shows data errors in design mode and in display mode, and also in a tag or attribute value\u2019s Point Detail page.<\/p>\n

    For example, if there is a data request for too many data points (exceeding a configured limit), an error is returned. Another example is a data error that is returned when a page component references a data item that does not exist (such as an entity that is not defined in the referenced hierarchy).<\/p>\n

    In version 4.5.3, Explorer helps you to identify the data errors and where they are originating within a page, by displaying a list of error items.<\/p>\n

    Open the Data<\/em> Errors<\/em> window by clicking the new Data<\/strong> Errors<\/strong> button on the Explorer ribbon. The button is only enabled when there are data errors on the page.<\/p>\n

    If you are in Display Mode, click the Data<\/strong> Errors<\/strong> button on the Page<\/strong> ribbon tab:<\/p>\n

    \"\"<\/a><\/p>\n

    If you are in Design Mode, click the Data<\/strong> Errors<\/strong> button on the Studio<\/strong> ribbon tab:<\/p>\n

    \"\"<\/a><\/p>\n

    In Point Details, click the Data<\/strong> Errors<\/strong> button on the Details <\/strong>ribbon tab:<\/p>\n

    \"\"<\/a><\/p>\n

    Each error item in the Data Errors window contains the name of the component (e.g. Data<\/em> Label<\/em>), the property that is experiencing the error (e.g. Value<\/em>), and a brief description of the error.<\/p>\n

    Hover over an error item in the Data Errors list; the component that has that particular error is boxed in blue, on the Explorer page behind the Data Errors window.<\/p>\n

    Components Showing Digital States<\/h2>\n

    Digital State Sets can be defined in Server and then applied to tags and calculations.<\/p>\n

    Here are some examples of digital state sets:<\/p>\n\n\n\n\n\n\n\n\n\n
    Digital State 1<\/strong><\/td>\n\u00a0<\/td>\nDigital State 2<\/strong><\/td>\n\u00a0<\/td>\nDigital State 3 <\/strong><\/td>\n<\/tr>\n<\/thead>\n

    In this release of Explorer, tags or calculations that are assigned a Digital State Set will display the string value (Name)<\/em> from the Digital State Set in place of the corresponding digital value (Value) <\/em>from that State Set, when used in any of the following of Explorer\u2019s page components:<\/p>\n
