\"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 4.5.5 introduces XY Mode in the Trend, as well as several minor usability enhancements for the Chart components. Hairlines, tooltips, and comment markers have received a facelift, following feedback from customers, and the current timestamp is now available on Point Detail pages for tags and attributes.<\/p>\n

 <\/p>\n

XY Mode in Trend<\/h2>\n

The Trend now includes an option to display time series data using either Time Series Mode<\/strong> or XY Mode<\/strong>. Time Series Mode, which is the default, displays time series data as values in time along the x-axis in the trace window. XY Mode is used to display a relationship or model between the traces, with one tag representing the range of values on the x-axis, and the other tags plotted along the Y Axis.<\/p>\n

XY Mode allows you to easily represent relationships or models rather than time series trends, such as PQ curves or pressure temperature relationships. XY Mode is very powerful for process analysis, as the calculation engine can be used to calculate regressions, correlation coefficients, residuals, and so on, and plot these on the same axis.<\/p>\n

You can set the data item you want to display on the x-axis by selecting a radio button against one of the rows in the trace table.<\/p>\n

When XY Mode is selected, you can still choose to have separate or shared y-axes, as well as a linear or log scale, and you can still choose to auto range the data; however, the raw sample methods and hairlines are not available.<\/p>\n

Trend Autorange<\/h2>\n

The way Autorange is calculated on a trend has changed to make more use of available space and to include more data.<\/p>\n

In this release, Autorange includes all data points within 5 standard deviations<\/strong> of the mean. The trend also uses the maximum and minimum values within that range to determine the range along the Y Axis. This means that the trend will now show more of the data, with fewer gaps.<\/p>\n

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

Autorange on the Trend in version 4.5.5<\/em><\/p>\n

In previous versions, when Autorange was selected, data points within 3 standard deviations of the mean were re-distributed along the Y Axis. Data points that occurred out of this range would be excluded, and a gap would appear in the trace line.<\/p>\n

Trend Range Selector<\/h2>\n

The Range Selector in the Trend now displays average values, with Autorange applied. This makes it easier to see changes to the trace line when the values in the trace window are similar.<\/p>\n

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

Range Selector autorange on the Trend in version 4.5.5<\/em><\/p>\n

In previous versions, it would display average values without Autorange applied. The Range Selector would only display autoranged values when it was applied to the whole trend.<\/p>\n

Updated Hairline<\/h2>\n

Following customer feedback, the hairline available for both charts and trends has received a facelift with a sleeker design which makes it easier to interpret at a glance. This addresses customer request SF373348.<\/p>\n

The timestamp has been split from the information box, and is now available at the top of the hairline.<\/p>\n

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

When you move hairlines so that they approach each other, the information box flips so that the values are not obscured.<\/p>\n

Data point values and other information is now available in separate information boxes, which are coloured to match the colour of the trace\/series.<\/p>\n

The Value Difference<\/strong> when using Dual or Multiple hairlines has also returned, and is displayed in brackets in the middle of the information box.<\/p>\n

Initially, the information box shows only 3 items: the data value, the value difference, and the comment icon. When you hover over the box, it expands to show the name of the data item.<\/p>\n
