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:
Filled
In a filled chart, each series is displayed as an area filled with the color specified in the chart configuration.

Line
In a line chart, each series is displayed as a colored line.

Bar
In a bar chart, each series is displayed as a colored bar. Each bar in the chart represents a time bin.

Series composition
Use the drop-down menu to select one of the following options:
Stacked
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.
Overlay
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 reorder them.

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 this.
Logarithmic
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 B.

Note

If 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 selection.
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.
Percentage
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.

Note

These 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 device.
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.
Title
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 templates button.
