Line Charts Visualization
Oracle Log Analytics provides a line chart visualization that lets you group by a numeric field, then graph the trend of values over time. Only numeric fields or aggregate output (sum as sum, average if the fields or output can be broken up by time) can be selected for the y-axis.
For example, to view the count of all Apache log entries, which are grouped by log source, over a period in time (say the last 7 days):
The count of Apache log entries grouped by Log Source is displayed.
Similarly, to view a graph displaying the average content size of the Apache log records over time, grouped by log source, from the Other section of the Fields panel, drag and drop the Content Size field to the Y-axis section in the Visualize panel. Ensure that you’ve selected the Average function from the Y-axis list.
You can select different statistical operations that you can perform on the selected field.
Note:
Some fields may not support all operations. For example, numeric operations, such as Average, Min, Max, Median, and so on won’t work on fields that are of data type String
