Histogram widgets can be used to display a distribution of customized numerical data directly on the Dashboard. The results of this graph are updated on the widget every time the Dashboard is refreshed.
Configure a Histogram Widget
When configuring the histogram widget, the following specifications are available.
|Saved Search||(Optional.) Open the drop-list and select a Saved Search to use as the data distribution for the histogram.|
Open the drop-list and select a value to show on the horizontal axis of the histogram. This value will always be a number (for example, size of a log).
The default X-Axis value is Raw Message Size.
(Optional.) Click the + Add Y-Axis Grouping button to enable a custom Y-Axis.
Open the drop-list and select a value to show on the vertical axis of the histogram. This value is almost always a count (for example, how many logs or signals).
|Scale Type||Select one of the following scales to determine how data is displayed on the Y-Axis.|
The Y-Axis values are displayed with equal distance between each plotted point. For example, in the following histogram, the data is shown with a gap of 500 between each value.
When the counted values are small, this can sometimes result in an unreadable graph, like the one in the example.
The Y-Axis values are displayed with exponential distance between each plotted point. This can allow for better visibility, as it creates a "taller" chart. For example, in the following histogram, the same data as above is shown with exponentially increasing values on the Y-Axis.
|Display Type||Select one of the following display types to determine how data is depicted in the histogram.|
The data is displayed as bars superimposed over each other for each X-Axis value with data. For example, shown below is the same data from the previous example displayed in bar chart form.
|Line||The data is displayed as parabolic lines visualizing the fluctuations in data.|
Enter a title for the widget.
By default, the title is <X-Axis field> Distribution.
