# Filters and perspective

Visualizations are available to help you gain deeper insights into your projects’ current statuses and histories.

### How do I compare current state for multiple projects or project components? <a href="#compare-current-state-multiple-projects" id="compare-current-state-multiple-projects"></a>

The Projects space allows you to filter the projects in your instance by multiple, measure-based criteria. Once you’ve chosen your set, you don’t have to stare at the raw numbers to identify the risks its projects face. Instead, several visualizations (**Projects** > **Perspective**) are available to help you understand each project’s relative position in terms of each of the major axes:

* Risk - reliability and security ratings, test coverage, technical debt, and lines of code
* Reliability - reliability rating, reliability remediation effort, lines of code, and bug count
* Security - security rating, security remediation effort, lines of code, and vulnerability count
* Maintainability - maintainability rating, technical debt, lines of code, and code smell count
* Coverage - coverage, complexity, and uncovered lines
* Duplications - duplicated lines %, lines of code, and duplicated blocks
* At the project level these same visualizations are available in the **Measures** tab to help you compare project components. The **Project Overview** corresponds to the **Risk** visualization in the **Projects** space, For the other five graphs, choose the **Overview** option under the relevant domain.

Additionally, tree maps are also available for percentage and rating metrics at the project level. Navigate to them in the **Measures** tab using the perspective selector in the right pane.

### How do I visualize metric history? <a href="#visualize-metric-history" id="visualize-metric-history"></a>

At the project level, the **Activity** tab offers several canned line graphs of selected metrics across time, with convenient mouseovers to show graph details and the ability to easily narrow the graph to a slice of the project’s history. Beyond the canned graphs, you also have the ability to map the metrics of your choice against each other in a custom graph.
