Table

The table can display different kinds of signals including enumeration Data type which is based on a verbal conversion formula (i.e. certain value ranges are mapped to certain output strings). (VTab), event, and string signals.

The table shows enumeration signals as follows: If a string value is available, it is displayed. If the enumeration signal has a default value, the table displays the default value for all numerical values for which there is no associated string value. If the enumeration signal has no default value and if there is no string value defined for a numerical value, "n/a" is displayed.

In an MDF This file is a binary file format for measurement data (MDF). This format is used to store, exchange and analyze measure data for automotive system development purposes. MDF files contain so-called meta-information like user, company, project, file comments etc. Typically for MDF format version V3.x the file extension *.dat is used. For MDF format version V4.x, the file extensions *.mdf or *.mf4 are used. measure file, single samples can be marked with an "invalid" flag. In the table instrument, these invalid samples are marked by a red exclamation mark.

You can perform the following actions:

• To define the table properties
• To scroll the visible time range
• To navigate to the start or end of the time range
• To move the synchronization time stamp
• To show or hide header rows
• To reorder columns
• To fill empty cells
• To change the number of decimals
• To change the data representation of a signal
• To delete signals
• To filter data rows

To see how you can use the possibilities of the Table instrument, watch our video Using the Table.

To define the table properties

The complete set of configuration possibilities for this instrument is available in the Properties docking window. There, the tooltips provide a detailed description of the properties and their possible options.

1. Do one of the following:

   • In the instrument, click .

     or

   • Select the instrument and press Alt+Enter.

     or

   • In the instrument, right-click and select Properties in the context menu.

To scroll the visible time range

To quickly navigate to a specific time stamp, you can use the time slider Control used for navigating on the time axis, including zooming functionality.. For more information, see Time Navigation and Synchronization. Alternatively, you can scroll by using the keyboard:

1. To move upwards, press the Page Up or Cursor Up key.
2. To move downwards, press the Page Down or Cursor Down key.

To navigate to the start or end of the time range

1. To navigate to the start of the time range, press the Home key.
2. To navigate to the end of the time range, press the End key.

To move the synchronization time stamp

In synchronized mode, the synchronization time stamp is highlighted in the second row in blue. If the synchronization time stamp is located between the first two rows, a blue line is displayed between these rows. For more information, see Synchronizing Instruments.

1. To move the synchronization time stamp, double-click a row.

   or

2. Use the keyboard:

   • To select a row above the current synchronization time stamp, press Alt+Cursor Up.

   • To select a row below the current synchronization time stamp, press Alt+Cursor Down.

To show or hide header rows

To distinguish signals that have the same name but are coming from different devices or different rasters, you can display the device, raster, or unit.

1. In the toolbar, click or use the tab Instrument in the Properties window.

   A list of the default header rows appears.

2. To show or hide a header row, select or clear the checkbox of the respective name in the list.

To reorder columns

1. Move a column by dragging its column header to the new position within the table header.

   A line between the columns appears together with highlighted areas on the left and on the right of the line.

2. Select the left or right highlighted area to place the column in front of or behind this line.
3. Release the mouse button.

To fill empty cells

1. If the value of a signal is not available, you can display its interpolated value. In the table toolbar, click .

   The empty cells are filled with the last available sample (so-called "step-mode" or "constant interpolation"). These values are shown in gray italic font.

2. To undo this action, click the icon again.

To change the number of decimals

1. Mark the columns for which you want to change the number of decimal places.
2. In the toolbar, click one of the following icons:
   • To show more decimal places, click .

   • To show fewer decimal places, click .

   The decimals for the time values can be adapted in the same manner.

To change the data representation of a signal

1. In the table, select one or more signals.
2. In the toolbar, click .
3. Select one of the following entries from the Data Representation drop-down menu:
   • Physical Values
   • Hexadecimal (memory) Values
   • Binary (memory) Values

   • Decimal (RAW) Values

   All selected signal values are shown in the selected data representation. The unit information is adapted according to the selected data representation.

   Note that if the device name of the signal ends with #MeasureCal, you must additionally select which data type shall be used to display the values. Select one of the following:

   • 8 bit
   • 16 bit
   • 32 bit

   • Do not cast

     In this case, the shown hexadecimal or binary representation for the Float value is according to the IEEE-754 standard.

To delete signals

1. Select one or more signals. Do one of the following:
   • In the instrument, mark one or more columns.
   • In the Configuration Manager, mark one or more signals.
2. In the context menu, select Remove.

To filter data rows

To reduce the shown amount of data to what is relevant for you, you can define a column filter per column. Only those rows (i.e. time stamps) for which the defined column filter conditions are fulfilled will be listed.

1. Click the funnel icon of the column.

2. Select from the conditions offered.

   Only one condition can be set per column.

3. Confirm the defined condition.

4. If needed, repeat the steps for other columns. Multiple column filters will be logically AND combined.

   Merely the rows for which all filter conditions are met will be displayed.

Note
Currently, a filter condition can be defined only for signals with numerical data. For signals with a verbal conversion, create a calculated signal using the Raw() function, and assign it to the table instrument. When the table contains signals recorded in different rasters the filtering happens on the interpolated data of the last available sample.

Column filters can be removed individually in the filter definition window, or per instrument using the icon.
