Information Displayed in Analyze Chart
Analyze chart for Link visualization is useful in visually identifying anomalies in the patterns. B default, a bubble chart is generated. However, you can select a chart from the options available.
Each row in the Link table represents a unique group. The size of the bubble represents the number of such groups that are contained in the bubble. The position of the bubble is determined by the values of the fields that are plotted along the x and y axes. Hover the cursor over a filter legend to view the following information:
-
Clusters: Number of bubbles in the chart for this legend value
-
Groups: Total number and percentage of groups across all the clusters
-
Average Cluster Range: Each bubble (cluster) represents a range of values. An average is computed for each bubble which shows the minimum and maximum averages across all the bubbles for this value. This is applicable only for numeric values.
-
Minimum Value: Lowest absolute value across all the bubbles for this legend range.
-
Maximum Value: Largest absolute value across all the bubbles for this legend range.
Change the Title of the Analyze Chart
To improve the readability of the chart and for friendly analysis, you can change the title of the bubble chart by using the option in the Analyze dialog box.
To modify the title of the Analyze chart, click the Settings icon next to the title of the chart, and click Edit Chart. The Analyze dialog box is displayed. Update the value of the field Chart Title, and click Submit.
As a result, the title of the chart is now changed to the value that you provided.
Control the Colors in the Analyze Chart
Two numeric fields are selected for plotting along the X and Y axes. The Time field can be used only for X-axis.
-
Any fields can be used to control the color of the bubbles. There are no restrictions about the types of the fields.
-
Numeric fields can be used for controlling the size of the bubbles. The value of the fields control the size of the bubble. The larger the values, the larger the bubbles.
For steps to select the fields for controlling the color of the bubbles in the chart, see Add More Fields for Analysis Using Size and Color.
The following chart shows the Time Taken for Requests, which is plotted along Y-axis, and also the Application and Job that are involved in the analysis:
By default, the Link Analyze chart automatically selects a color palette
based on the values in the chart. To select a different palette or to add additional
field values, click the Color link. In the following example, the field
Event Type
has Audit Analysis
color palette
applied for different values:
'Log Source' = 'OCI Audit Logs'
| link Time, Event
| eval 'Event Type' =
if(indexOf(Event,upload) != -1, Insert,
indexOf(Event,update) != -1 or indexOf(Event,literal(patch)) != -1, Update,
indexOf(Event,delete) != -1,Delete,
indexOf(Event,get) != -1 or indexOf(Event,list) != -1, Read, Other)
| classify 'Start Time','Event Type' as 'Audit Analysis'
