Graph Parameters

The parameters on the right side of the Graph Display Layout Editor can be broken down into five groups:

￭

Basic Parameters

Basic Parameters

Parameter

Description

Label

The table or histogram name that will be displayed in the left column of the Graph panel.

View

(Tables only) Select the default type of data displayed by this table's cells:

￭

Max: Show the highest value observed for the cell.

￭

Min: Show the lowest value observed for the cell.

￭

Average: Show the average value observed for the cell.

￭

Last: Show the last observed value for the cell.

￭

Count: Show the hit count for the cell.

NOTE: When viewing this table in the Graph panel, this selection can be overridden by the icons above the table.

View Zoom Data Only

When this box is checked, the table or histogram will display only data gathered during the time frame that you select in the Chart vs. Time panel.

If this box is left unchecked, the table or histogram will show data gathered during the entire length of the recording.

NOTE: When viewing this table or histogram in the Graph panel, this selection can be overridden by the icons above the graph.

Parameter

(Tables only) Click this link to select the signal (sensor or PID) whose output values will be mapped in the cells of the new table.

Unit

Once the Parameter is selected, use this dropdown to select the units for this parameter. For example, Spark Advance can be displayed in degrees or radians.

Decimals

(Tables only) The number of decimal places displayed for cell data.

Filtering

The fields in this group are used to filter out data that should not be included in the graph.

Function

If a function is entered here, each frame of data received will be checked against this function.

￭

If the function evaluates as TRUE for the frame, the data in the frame will be added to the graph.

￭

If the function evaluates as FALSE, the data from the frame will NOT be added tot he graph.

See Expression Filtering for more information in defining filter functions.

Cell Hits Required

(Tables only) The field is used to specify the minimum number of cell hits required to register data on the graph. Entering a higher value here can help remove erroneous data by filtering out cells that do not have enough data for accurate feedback.

Shading

Table cells can be colored based on the values they contain. The parameters in this section define what values will be colored and what colors will be used.

Parameter	Description
High Value	Cells whose values are equal to or above the number entered here will be given the color in the box to the right. (Click the box to select a different color.)
Mid Value	Cells whose values are between the Low Value and High Value will be colored with lighter shades of the two colors selected. The value specified here is used to set the value at which the colors shift from shades of the Low Value color to shades of the High Value Color.
Low Value	Cells whose values are equal to or below the number entered here will be given the color in the box to the right. (Click the box to select a different color.)

Parameter

Description

High Value

Cells whose values are equal to or above the number entered here will be given the color in the box to the right. (Click the box to select a different color.)

Mid Value

Cells whose values are between the Low Value and High Value will be colored with lighter shades of the two colors selected.

The value specified here is used to set the value at which the colors shift from shades of the Low Value color to shades of the High Value Color.

Low Value

Cells whose values are equal to or below the number entered here will be given the color in the box to the right. (Click the box to select a different color.)

Column Axis

The configuration options in this section specify the values displayed on the column axis of the table or histogram.

Parameter	Description
Parameter	Click this link to select the signal (sensor or PID) whose output values will be used for the column axis of the table or histogram.
Unit	The units for the selected parameter.
Header Cell Factor	(Tables only) the header values entered below will be divided by this value to determine the values actually displayed at the top of each column. For example, if the column header value entered is 1200 and the Header Cell Factor value is 1000, the actual value displayed at the top of the table will be 1.2.
Values	The values for the column headers, separated by spaces. NOTE: You can copy the labels from an existing table in VCM Editor by right-clicking on the original table and selecting Column Axis > Copy Labels. Then, right-click on this field and select Paste.

Row Axis

(Tables only) The configuration options in this section specify the values displayed on the table's row axis.

Parameter	Description
Parameter	Click this link to select the signal (sensor or PID) whose output values will be used for the row axis of the table.
Unit	The units for the selected parameter.
Header Cell Factor	The header values entered below will be divided by this value to determine the values actually displayed at the left end of each row. For example, if the row header value entered is 70 and the Header Cell Factor value is 10, the actual value displayed at the top of the table will be 7.
Values	The values for the row headers, separated by spaces. NOTE: You can copy the labels from an existing table in VCM Editor by right-clicking on the original table and selecting Row Axis > Copy Labels. Then, right-click on this field and select Paste.
