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.

Create new wildcard series

Adds an empty wildcard series to the chart.

Chart Type

To choose one of the following chart types, use the Type buttons on the left side of the toolbar:

Filled

In a filled chart, each series is displayed as an area filled with the color that is 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.

Heatmap

In a heatmap chart, each series is displayed as a heat map. Each counter is shown on a separate line and the bin color intensity increases in proportion to the number of samples.

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 the series that are 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, they are 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. Their position in the chart control determines the front-to-back ordering. To prevent series from obscuring data, as shown in the following figure, place series with larger values 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. For example, Data Read Requests and Data Read Hits.

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. A logarithmic chart displays with a series of horizontal lines, which increase in value by a power of ten.

Note

The charts cannot show negative numbers, so values less than one, which have a negative value in log space, appear as zero.

Average Selection

The cross-section marker overlay shows the average value of all bins that are included in the selection. If not selected, the overlay shows the total value of all bins in the selection.

Average Cores

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

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.

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.
