From the Attribute Explorer, you can right-click any data attribute to display a suitable pop-up menu of options:
Select one of the display methods to open the appropriate data display window.
4.5.1 View data in a Map
1 Use the pop-up menu to display the data attribute (UE_TxPow in this UMTS example) in a map window on a new layer.
If the title of a particular series is too long to see easily in the legend pane, right click on the series name and select Multipath from the options to split the name over two lines.
The legend panel shows the how the various colors used relate to values for the particular attribute. The number in parentheses is the number of binned data points for that value range that occurs in the logged data, followed by the percentage of the total number of binned data points.
2 If there are no other attribute layers on this map, the new attribute layer will be
beneath the lowest site or cell layer. See the chapter Configuring Analyzer for more information on map layers.
2 Click on the Pan button.
3 Click and drag the data around the map window.
4 Experiment with the Zoom buttons.
5 In the Attribute Explorer, open the 'Event Data' set and drag an event type (in this example the Uu_CallDropped event) onto the map, which should then look similar to this:
Adding events to the mapped data can help you see where problems are occurring.
6 Drag another attribute onto the map.
The attribute information is displayed on a new map layer directly above the previous attribute layer.
You can also change the size, symbol or color of the data, apply offsets to an attribute or merge attributes for a multidimensional display. See the online help for further details.
7 To hide the data for an attribute, go to the legend pane and click in the check box beside the attribute name.
To find out how to add background geographical and network information to map windows, see the chapter Configuring Analyzer.

4.5.2 Replay the data
With a drive test file, you may want to recreate the drive test by 'playing' through the data file from beginning to end. You can do this using the Replay control from the Home tab.
To move through the messages by one message at a time, click on a Step button:
Several clicks may be required before any change is visible on the Map, depending on the binning settings.
To move through each message at a set speed, click a Play button:
This will move through the data at a multiple of real-time speed set using the slider (if the Play by Time option is selected – see below).
The Mode dropdown button allows you to set the replay mode:
Mode Play Step
Time Replays message at the same rate as originally recorded. Some messages will be ignored to maintain the replay speed.
Step to next message.
Message Replay all messages. The speed slider has no
effect. Step to next message.
Bin Replays bin-to-bin in sequence. The speed slider has no effect.
Step to first message in next bin.

4.5.3 View data in a Form
While examining data on a map, you can also view data attributes for the same data point by using Forms (also called StateForms).
1 From the View menu, select Forms and select an appropriate StateForm (or, from the Attribute Explorer, right-click on a stream name, select Display Form and then the form name).
2 In a map window, click Select and select a data point.
The Form window now displays a variety of attributes based on the data point you selected. Here is an example:
You can synchronize all views in other open data windows by clicking on the timeline in Navigator-type StateForms like this.
2 Other StateForms provide information for the currently selected point in the drive
test:
3 If you have scanner data in your logfile, start another Form window.
4 Right-click on the form and select Open File, then select a form (.axw) file for a scanner.
5 Right-click on the form and select Stream Selector, then the scanner stream.
See the online help for details on how to create your own forms.

4.5.4 View data in a Chart
To display an attribute in a chart
From the Attribute Explorer window, use the pop-up menu to display a data attribute (in this example, 'EcIo_1stBest') in a chart window.To display an attribute in an existing chart
You can display more than one attribute on the same chart.
Select a second attribute that would make a useful comparison (in this example, the attribute 'ForwardFER') and drag it onto the existing chart.2 To zoom into a chart
You can zoom into selected areas of the chart by defining a frame for the zoom.
1 On the chart, click the upper left corner of the zooming rectangle, and drag down to the lower right extent of the rectangle.
2 Release the mouse button to complete the zoom action:
Note that the zoom only operates in the X-axis, not in the Y-axis.
3 Now return the chart its original state by dragging a box anywhere, but this time starting from the bottom.
To pan and scroll around the chart
Put the cursor within the chart window, hold the right mouse button down and drag the cursor around to pan and scroll around the chart window.Although you can scroll in the X-axis for all attributes on the chart, you can only pan in the Y-axis for the last attribute to be displayed on the chart.

4.5.5 View data in a Table
Tables let you examine the numeric series, histogram and statistical data for the selected attribute.
1 From the Attribute Explorer, right-click on a data attribute (in this example, 'DownLink Measurements > EcIo_1stBest') and select Display on Table.
This opens the Table window:
2 Experiment with the other tabs in the window.
4.5.6 View data in a Workbook
Workbooks let you examine the data for the selected data attribute within a Microsoft Excel™ spreadsheet.
1 From the Attribute Explorer, right-click on an attribute and select Display on Workbook to open the spreadsheet.
2 See also the section Generate new reports on page 50.

4.5.7 About synchronized data windows
The data in each of these windows is synchronized, so that when displaying the same data attribute in a map, chart or table, if you select a data point in one window, all related map, chart or table windows also highlight the data point.
Open a map and a chart window, and display an attribute in each.
1 From the map window, click on Select.
Note the other toolbar buttons for selecting data points.
2 Click on a data point - a line appears at the equivalent time on the chart:
