5.4.2 Chart configuration toolbar options
The toolbar of the Chart Configuration panel defines options that apply to all series in a chart.
It has the following options:
- Create a new series
Adds an empty series to the chart.
- Chart Type
Use the Type buttons on the left side of the toolbar to
choose between one of the following chart types:
In a filled chart, each series is displayed
as an area filled with the color specified in the chart
In a line chart, each series is displayed as
a colored line.
In a bar chart, each series is displayed as
a colored bar. Each bar in the chart represents a time
- Series composition
- Use the drop-down menu to select one of the following
In a stacked chart, the data for different
series are stacked on top of each other. So, the highest
point of a stacked chart is an aggregate of data from all of
the series contained in the chart. For example, if the first
value of series A is three and the first value of series B
is five, the first data point in the stacked chart that
contains these series is eight.

- Stacked charts are appropriate when the events
are counted in exactly one of the series in a chart. For
example, this is useful in a case where a chart contains both
Data Read Hits and Data Read Misses.
In an overlay chart, the different series
overlap each other. The front-to-back ordering is determined
by their position in the chart control. To prevent data from
being obscured by other series, as shown in the following
figure, ensure series with larger values are placed above
series with lower values in the chart control. Drag and drop
series controls using the chart configuration panel to

from series B
- Overlay charts are appropriate when some of the
events are counted in more than one series in the same chart.
Data Read Requests and Data Read Hits are a good example of
- Shows all data points on a log10(y) scale where
y is each Y-axis data point in the chart. This Y-axis modifier
is useful when there is a huge difference between the minimum
and maximum values in a chart. In charts with these huge deltas,
it can be hard to differentiate between the lower value data
points in the chart. Setting the Y-axis modifier to Logarithmic
can give you a better visual representation of your data in
these cases. A logarithmic chart displays with a series of
horizontal lines in Streamline, each line represents an increase
in value by a power of ten, so that if data point A sits exactly
one line higher than data point B, A is ten times higher than
NoteIf the actual value of a data point
in a Streamline logarithmic chart is less than one, it
appears in the Streamline chart like a zero value. This is
because the logarithmic value of such a data point would be
a negative number.

- Average Selection
- If you select this option, the Cross Section Marker overlay
shows the average value of all bins included in the selection. If not
selected, the overlay shows the total value of all bins in the
- Average Cores
- Select this option to plot values in a multi-core chart as
the average of all cores, unless you have used the multi-core disclosure
control to show metrics per core. If not selected, the multi-core chart
shows the total for all cores.
- Select this option to plot values as a percentage of the
largest value in the chart.
The following energy offset buttons allow you to align energy data with the
other data in the view.
NoteThese buttons are disabled if there is no energy data in the chart. To capture
energy data you must have either an Energy Probe or a supported NI-DAQ
- Offset energy chart data to the left
- Manually adjusts the energy data to the left.
- Reset energy chart offset to zero
- Returns the energy data to its original position.
- Offset energy chart data to the right
- Manually adjusts the energy data to the right.
- Link adjustments to other charts
- Links the adjustments made to the current energy chart to
the other energy charts in the capture.
- Use this field to give the chart a title. The title appears
at the top of the chart handle.
- Remove Chart
- Removes the chart from the view. If you have saved the chart
in a chart configuration template, you can add it back to the view later
using the Switch and manage
