Data Trace Import Dialog Box

The Data Trace Import dialog box allows you to import an external format of trace which is different from the trace format of CodeWarrior Software Analysis. This trace format is generated from an external trace collection tool and can be saved in an input file in a text format. The trace data contained in this input file is converted into a format compatible with CodeWarrior. A sample input file, dsc8257_Data_Visualization_1.txt, is located at <CWInstallDirectory>\MCU\morpho_sa\sasdk\data\fsl.testdata.sa.trace\ and <CWInstallDirectory>\eclipse\plugins\com.freescale.morpho.sa.arm_*\data\fsl.testdata.sa.trace.

To import external trace format into your project:

1. Click the Import Data Trace from text file button in the Software Analysis view to display the Data Trace Import dialog box.
2. Locate the Input File.
3. From the Output Project drop-down list, select the project where you want to import the trace format.
4. Select the architecture for which the trace was collected from the Select Platform drop-down list.

5. Click OK.

   The results of the input file get displayed in the Software Analysis view. Two hyperlinks appear, Trace and Data Visualization.

The Data Visualization graph allows you to monitor variables of your application. You can identify and chart variables of the application against time. The chart displays tooltips when you place mouse cursor over the circular data dots.

The symbols have different sizes, so that multiple series points which coincide (ox/oy values) are visible. You can change the values displayed on the ox (time) axis between time and any of the series.

You can zoom-in and zoom-out the information in the graph using mouse scroll up and down. You can also select a particular area on the graph to zoom-in the information. Right-click in the graph to open a context menu, which allows you to:

• adjust X and Y axis range,
• show/hide legend,
• zoom-in/zoom-out the graph,
• zoom-in/zoom-out information on X axis or Y axis,
• save graph as picture,
• set various properties of graph such as color, legend, and grid style, and
• change series appearance, for example, show/hide, line color, symbol color/shape/size, show/hide labels
• logarithmic scale.
