To help you troubleshoot, Netdata +synchronizes every chart every time you interact with one of them. + +Here's what synchronization looks like: + +![Animated GIF of the standard Netdata dashboard being manipulated and synchronizing +charts](https://user-images.githubusercontent.com/1153921/80839230-b034a800-8baf-11ea-9cb2-99c1e10f0f85.gif) + +Once you understand all the interactions available to you, you'll be able to quickly move around the dashboard, search +for anomalies, and find root causes using per-second metrics. + +## Pause or stop + +| Interaction | Keyboard/mouse | Touchpad/touchscreen | +| :---------------- | :------------- | :------------------- | +| **Pause** a chart | `hover` | `n/a` | +| **Stop** a chart | `click` | `tap` | + +By hovering over any chart, you temporarily pause it so that you can hover over a specific timeframe and see the exact +values presented as dimensions.

Zooming out lets you see metrics within the larger context, such as the last hour, day, or +week, which is useful in understanding what "normal" looks like, or to identify long-term trends, like a slow creep in +memory usage. + +## Select + +| Interaction | Keyboard/mouse | Touchpad/touchscreen | +| :------------------------------ | :-------------------------------------------------------- | :------------------- | +| **Select** a specific timeframe | `Alt + mouse selection` or `⌘ + mouse selection` (macOS) | `n/a` | + +Selecting timeframes is useful when you see an interesting spike or change in a chart and want to investigate further. + +Select a timeframe, then move to different charts/sections of the dashboard.

Another valuable way to interact with charts is to use the [timeframe +selector](/docs/dashboard/select-timeframes.mdx), which helps you visualize specific moments of historical metrics. + +If you feel comfortable with the [dashboard](/docs/dashboard/how-dashboard-works.mdx) and interacting with charts, we +recommend moving on to learning about [configuration](/docs/configure/nodes.md). While Netdata doesn't _require_ a +complicated setup process or a query language to create charts, there are a lot of ways to tweak the experience to match +your needs. + +### Further reading & related information + +- Dashboard + - [How the dashboard works](/docs/dashboard/how-dashboard-works.mdx) + - **[Interact with charts](/docs/dashboard/interact-charts.mdx)** + - [Chart dimensions, contexts, and families](/docs/dashboard/dimensions-contexts-families.mdx) + - [Select timeframes to visualize](/docs/dashboard/select-timeframes.mdx) + - [Import, export, and print a snapshot](/docs/dashboard/import-export-print-snapshot.mdx) + - [Customize the standard dashboard](/docs/dashboard/customize.mdx) |
