# Get started with Charts beta

NOTE

Charts are currently in beta testing and only available to a few customers via our Early Adopter program. To join an Early Adopter program, contact your Cognite representative.

Cognite Charts runs on top of Cognite Data Fusion (CDF), which collects, cleans, and contextualizes industrial data to make the data accessible and meaningful for humans and machines.

Charts is a powerful tool for engineers and domain experts to explore, trend, and analyze industrial data. It gives industrial experts instant access to data and no-code tools to find, understand and troubleshoot for actionable insights. Charts is cloud-native and is speedy compared to traditional tools. It runs securely on any computer in your desktop browser with a single, secure sign-in.

If you are doing routine tasks or troubleshooting complex issues where you need access to industrial data, Charts makes this fast, repeatable and collaborative - all in one tool. You can find and work with any time series or contextualized P&ID available in your organization's Cognite Data Fusion. You can also find and analyze data you find in other Cognite applications for a seamless collaborative experience.

# Open Charts

To open Charts, navigate to https://charts.cogniteapp.com/ (opens new window), type in your company name, and sign in with your company ID and credentials.

Currently, we recommend that you run Charts in Google Chrome.

Start a new chart or open a private or public chart on the Overview page. Find data to plot with the search icon in the top left corner on the New chart page.

# Exploring data

Search by equipment tag name or description to see a list of time series connected to the relevant assets. Review the assets using the sparkline time series preview that shows sensors with the data you're looking for.

Assets found in one or more P&IDs are displayed with a Document icon in the search result. Click the icon to browse the P&IDs and add data to the chart. Then rename, remove, or customize the data using the available tools.

All vertical axies are interactive, and can be independently moved by click+hold and drag, or scaled in and out by hovering over each respective horizontal axis and scroll using your mouse. This allows for fast stacking, overlay and comparison of trends of multiple time series. Navigate between current and historic data with the Last year, Last month, and Last day buttons or setting a specific time and date. Each time series can be made visible or hidden by clicking the relevant color dot in the list below the chart.

Customize the trend by adjusting colors, line thickness, and dotted or dashed lines.

# Calculations and analysis

Troubleshooting and working on root cause analysis often require calculations ranging from basic algebraic to more advanced algorithms. You can easily apply these calculations to one or multiple time series, and the results are directly available in the chart.

To start a new calculation, click New calculation, and navigate to the calculations tab by selecting the calculation or pressing the Calculations tab in the lower left corner. Right-click in the black work area and add one or more input time series to get started.

# The Constant or Toolbox Function

Right-click to add Constants or Toolbox Functions to the work area. Double-click the Toolbox Function to select and add a function. Add any input parameters before you save.

Right-click again to add an Output time series for the calculation to be written back to the chart area. Pipe the calculations together in the right order to complete the computational graph, and click Run to start the calculation, and show the results in the graph as a new, calculated time series.

Adjust input parameters and constants values at any time by double-clicking a Toolbox Function or Constant. Click Run to calculate with the new input parameters.

# Collaboration and sharing

Charts can be private or public. You can share a link to public charts with co-workers with access to the Cognite Charts project. All users in your organization can see the charts under Public charts on the Overview page.

Only the owner of a chart can save changes made to Public charts. To save changes to a chart you don't own, duplicate the chart with the Duplicate option on the Actions menu and save changes to the copied chart.

You can use duplicated charts to create template charts with pre-selected time series and calculations that you can reuse when performing troubleshooting or root cause analysis and share with your team.
