Which of the following is NOT a capability of the chart builder tool?

The chart builder tool within Fortinet FortiAnalyzer is primarily designed to facilitate the visualization and manipulation of data through the creation of various types of charts and graphs. It allows users to customize data visuals to meet specific needs, generating charts that can display various metrics derived from analyzed data.

Creating a dataset from search results is a fundamental capability of the tool, enabling users to extract relevant information from logs and observations to feed into the chart-making process. In addition, while the chart building tool aids in presenting data visually, it does not inherently include the capability to generate comprehensive reports based solely on those charts. Reports typically require additional functionality that is not exclusively part of the chart builder tool, which focuses on data visualization rather than report generation.

Thus, the ability to analyze historical trends is not the correct answer; rather, it is a feature that supports the purpose of the chart builder, helping users to view comparisons and progress over time. The chart builder's main function is not to provide analytical summaries but rather to create visual representations of data, reinforcing why generating a report based purely on the chart is not a fundamental capability of this tool.
