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, specific to that series that enable you to customize both the data used to plot the chart and its look and feel.

Figure 5-18 Series options

Series options

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 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 on the color box in its series control. This opens a 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. Press Ctrl + Space or the $ symbol to activate a drop-menu that shows you a list of counters. You can select a counter in this Content Assist list to see its description. Click on a counter to add it to the Expression field. 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 parentheticals 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. The result is y if x is non-zero or z if x is zero. Only one of y or z is evaluated.

abs
Returns the absolute value of the numeric expression 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 rounded to an integer.

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

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 using 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 represented by the time bin, then converts it 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 recorded for any millisecond within that second.

Note

In most cases, Minimum provides the lowest value for each millisecond within any time bin. If you have High Resolution Timeline enabled, Minimum provides the lowest value per microsecond, if the given counter provides that level of detail.
Unit
Enter the unit type for the series. The value you enter in this field appears when you use the Cross Section Marker to select one or more bins.
Remove Series
Removes the current series from the chart.
