The following sections provide a quick reference for SAP xApp Manufacturing Integration and Intelligence (SAP xMII) Java Applet users in manufacturing intelligence applications. A detailed reference for each applet can be found in the Applet Reference topic.
The following functionality is available unless the application developer who designed your Web page disabled it:
Double-click on the chart to refresh it to the current date and time (identical to selecting the zoom to current time button).
Click on a tag name in the legend to change the Y-axis to the ranges associated with the tag and to display the description associated with the tag.
Move your mouse over the chart to display the X and Y values at the mouse pointer location.
Right-click on the chart to view a variety of menu options for scrolling, zooming, selecting data points, changing the chart appearance, etc.
Additionally, you can enable the following capabilities:
Single-click or double-click on a point to enable point-by-point drill downs.
Set up drill downs through single-clicks or double-clicks on the chart.
Customize what query result set attributes are shown in the upper right-hand corner of the chart.
The Zoom and Scroll functions are the same as the functions on the Time Control and Navigation Bar. The Query Properties and Display Properties are explained below. Printing is also explained below. The Data menu allows you to download the data behind the chart in its raw form or get summary statistics of the data. You may also download the applet's raw data in CSV format and analyze it in other tools such as spreadsheet applications. The iGrid also has a right-click menu.
There are two shortcuts that you can use when you are getting data detail from the right-click menu:
Press the Shift key to call an http "get" method with the name-value pairs used for the query visible in the command line of the browser.
Press the Ctrl key to return the data set as an XML file.
The navigation bar, shown below, is used for selecting the time interval, enabling/disabling automatic refresh, and refreshing/updating your chart on demand.
Click the light bulb button to enable automatic refresh. If the button is active, the other buttons are inactive. Click the button again to disable automatic refresh; the button is grey when it is inactive.
The two buttons next to the light bulb button are the Zoom In and Zoom Out buttons. To select a zoom area, click and drag your mouse on the chart to select a zoom region, then select the Zoom In or Zoom Out buttons.
The arrow and diamond buttons handle time scrolling. The left most left arrow button scrolls back in time one full screen of data. Therefore, if you are looking at a one hour chart, it scrolls you back one hour. The second left arrow button scrolls back one quarter screen of data or, in our example, 15 minutes. The diamond button updates the chart to the current time. The first right arrow button scrolls forward one quarter of a screen, and the last right arrow button scrolls forward a full screen.
Click either of the two buttons with the date/time
values displayed to select date and time values from a calendar. To pick
a date, click on the desired date. You can select a month from the
drop-down list or select a year by scrolling forward or backwards using
the arrow buttons next to the year. You can select an hour/minute/second
via the spin buttons or via the speed bar, the scroll bar below the date,
which allows you to quickly select time values in 15-minute increments.
When you change either the start or end date/time, the chart automatically
updates. To select both the start date/time and end date/time, select
QueryProperties | Time Interval from the right-click menu.
You can right-click your mouse button on a chart and select the DisplayProperties | ChartProperties menu item if it is enabled. From there, you can change virtually any property in the chart. The pop-up windows for each type of property show a detailed list of the available parameters. Changes are temporary unless you save a template containing these values (see below). These parameters are described in more detail in the Applet Reference topic.
You can right-click your mouse button on a chart and select the Query Properties | Select Tags menu item if it is enabled.
From this dialog, you can select the tags you wish to chart and browse other available data sources. You can also use the mask field to provide a subset of the available tags. When entering a mask, use the percent sign (%) as a wildcard for matching. For example, to get all tags that begin with TIC, enter "TIC%" as the mask, and then click the Apply button.
You can add or remove tags from the selected tag list using the buttons next to the selected tag list. You can also manually type a tag name into the entry field, and click the Add button to add it to the list.
To browse available data sources, click the Select Data Source button. From this dialog, you can browse the list of available servers from which you can select tag data points for your chart.
In addition to using the navigation bar, you can also select a time interval in a historical or time-related chart by selecting the Query Properties | Time Interval menu item. This displays a dialog from which you can select the time interval.
The only free format data entry field is the Time field which has a special format of day@HH:mm:ss, where day is any of the following: Today, Yesterday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday. The time is in military (24-hour) format and must include minutes and seconds. As an example, to view data for today at 4:30 PM, the value is Today@16:30:00. The chart then sets the start time to this value and displays a chart width based on the Duration and DurationUnits you selected. You can also select specific start and end dates, modify the duration (width) for the chart, and also select from a predefined list of time periods or schedules that your system administrator has defined.
You can load and save both query and display templates via the pop-up menu items on a chart. A dialog box appears when you load or save either type of template. The dialog displays a list of available folders and templates from which you can load templates or to which you can save templates.
If you wish to print your chart, right-click the chart and select the Print menu option. A new browser window is created with a copy of your chart as a Web graphic. You can then print it by selecting your browser's print option.
Mouse tracking is a configurable feature of the iChart applet. Mouse tracking data appears in the upper left-hand corner of the applet and shows the current location of the mouse or the value of an object (bar, line, data point, etc.) at the position of the cursor in the chart area. When ShowMouseTracking is enabled for the iChart, the default mouse tracking format is "TagName : XValue : YValue : DatalinkValue." The configurable settings for the mouse tracking area are detailed in the iChart Reference topic.
