SciChart.js Licensing

To try out SciChart.js, you will first need to start a trial. You can do this using our cross-platform licensing wizard which is common to all SciChart platforms.

Download the licensing wizard from here and install on your PC or Mac.

Next, log in to the Licensing Wizard using your scichart.com username and password. If you do not have an yet, you can create one here.

Once logged in, click “Start Trial” on the Trials tab for SciChart.js.

Your SciChart.js applications on localhost will search for the licensing wizard to validate the trial license locally. Leave the licensing wizard open or minimise to tray while developing!

When you have a paid SciChart.js developer license, to deploy an application to a domain you need to register that domain with your account.

First, set set a domain at scichart.com/profile:

Next, generate a Runtime Key also at scichart.com/profile.

The Runtime Key must be placed in your application once before any SciChartSurface is shown or instantiated, for example in a Root component in a React App.

Code samples below:

// Set a runtime key in JavaScript once before any SciChartSurface is created
SciChartSurface.setRuntimeLicenseKey("YOUR_RUNTIME_KEY_HERE");

Note: You can register a single domain for each developer license you have purchased. Site licenses or company-global licenses can register unlimited domains.

Make sure you update your runtime keys after adding a new domain!

#3 Respond to Invitation

You will receive an email with an invitation to join the SciChart.js Github repository! Accept the invitation to get access!

If you cannot manage to get your application working with the license applied, please check out our licensing troubleshooting steps below or contact us and we will do our best to help.

Trial Expired or Invalid License Problems

Sometimes people report that after deploying their application, the Trial Watermark still appears, or, end users see Trial Expired.

Follow the steps below to debug this.

1. Enable License Debug info: If you contact support with a licensing issue, we will usually ask you to do the following. Use your browser dev tools to set a Local Storage key called LICENSE_DEBUG with value 1, as shown below. This will output much more information to the console, which you can copy and send to us.
   
2. Check support expiry date: if your support subscription has expired, then you cannot use the latest versions of SciChart. You can check your support subscription at the profile page or in the cross platform licensing wizard. Contact sales to renew your license, as discounts are available if you renew promptly!
3. For localhost: check the Licensing Wizard application is open and you have activated your developer license. Licensing error messages are reported to the browser console, and SciChart.js periodically has to check the licensing wizard for a valid license key.
4. Check the Runtime License Key is set: Follow the steps above to set your Trial or Paid Runtime License key in your app. Without this, the app will not work!
5. Ensure Runtime Key is set once before any SciChartSurface is created: The SciChartSurface.SetRuntimeLicenseKey method must be called once before any SciChartSurface is instantiated.
6. Configure the License Wizard Port: For trials and local development, SciChart communicates with the license wizard using a small web server running as part of the license wizard. By default this listens on port 24278. In rare cases this port may be unavailable due to other services on your machine.
   • Licensing wizard version 6.0.330 and later will alert you if the default port is not available and if an alternative port could be found.
   • Click the alert to go to the debug tools section of the about page. There you can check or set the port. If the License wizard cannot listen on the port you specify, it will search up to 100 ports up from there.
   • Set a Local Storage key called LICENSE_WIZARD_PORT. If you cannot guarantee a single port, but only a range, then you can also set a Local Storage key called LICENSE_WIZARD_MAXPORT which will cause SciChart to try to contact the wizard on ports up to that value.
7. Delete Cookies and refresh the page. Licensing info is cached in a cookie called scLicense. If you have done all the above and still experiencing trouble, find and delete this cookie and refresh the page before contacting support.
