Chart configuration series options

Each chart in the Live or Timeline view contains one or more series or sets of data. Each series has a set of options that enable you to customize the data that is used to plot the chart, and its look and feel.

You can use the handle on the left side of each series control to reorder the series in the chart. You can also use it to move or copy the series to another chart. To move the series, drag and drop it. To copy the series to another chart, hold down the Ctrl key while dragging it. When moving the series to another chart, make sure that the chart configuration panel is open for the destination chart.

Each series in a chart contains the following options:

Color

To change the color of a series, click the color box in its series control to open the Color dialog box.

Name

Enter a name for the series. This name appears next to the chart color in the chart key.

Description

Enter a description for the series. When you hover over the series title or color, a tooltip appears, containing the description defined here.

Expression

Use this field to define the data set that the series uses. Open a drop-down list of counters by pressing Ctrl+Space or the $ symbol. To see a description of a counter, hover over it in the list. To add a counter to the Expression field, select it in the list. You can create an expression using more than one counter by using a combination of counter names and any of the following operators: >, <, >=, <=, ==, !=, ||, !, &&, %, *, /, +, -. You can use parentheses to define the order of operation.

In addition to the mathematical and comparative operators, you can use the following functions in the Expression field:

if

Evaluates whether a condition is true or false before applying an effect.

Usage: if(x, y, z), where x is the expression to be analyzed. If x is nonzero, the result is y. If x is zero, the result is z. Only one of y or z is evaluated.

abs

Returns the absolute value of the numeric expression that is specified as the parameter.

Usage: abs(x), where x is a numeric expression.

ceil

Returns the smallest integer that is greater than or equal to the numeric expression given as a parameter.

Usage: ceil(x), where x is a numeric expression.

floor

Returns the largest integer that is less than or equal to a numeric expression given as a parameter.

Usage: floor(x), where x is a numeric expression.

max

Compares the arguments and returns the greater value.

Usage: max(x,y), where x and y are numeric expressions.

min

Compares the arguments and returns the lesser value.

Usage: min(x,y), where x and y are numeric expressions.

round

Returns a numerical value that is rounded to an integer.

Usage: round(x), where x is a numeric expression.

You can also use the following built-in variables:

$ZOOM

This variable is the bin size of the current zoom level, in seconds, given as a floating-point value. For example, when showing the 200ms zoom level, this variable has the value 0.2.

Note

When used independently from source data, entering constants in the Expression field can yield inconsistent results.

Filters drop-down menu

Depending on the class of the counter selected, you can select one of the following filters to apply to all the values in the series. To select the filter, use the drop-down menu in the series options panel:

Average

Works the same way as Minimum, except that it displays an average value for each time bin.

Accumulate

Displays the accumulated value of all the samples in the time bin.

Hertz

Converts the counter to a rate. It takes the value for each time bin and divides it by the unit of time that the time bin represents. It then converts the result up to seconds. You can use it to convert a cycles count into cycles per second.

Maximum

Works the same way as Minimum, except that it displays a maximum value for each time bin.

Minimum

Displays the minimum values for the counter for each time bin in the current zoom level of the Timeline view. So, if the current zoom level of the Timeline view is one second, Minimum displays the lowest value that was recorded within that second.

Unit

Enter the unit type for the series. The value that you enter in this field appears when you use the cross-section marker to select one or more bins.

Remove Series

To remove the current series from the chart, click Remove Series .
