Setting a Runtime License on a SciChartSurface

Another static method which allows you to license SciChart (apply a trial or paid production or test license) is SciChartSurface.setRuntimeLicenseKey()

All of our instructions for licensing can be found at the page scichart.com/licensing-scichart-js. A quick code sample is below. Ensure that you call this function once before any SciChartSurface is shown with a valid runtime key.

import { SciChartSurface } from "scichart";

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

Notes on Licensing​

  1. SciChart licensing is two-step. We have a developer license for localhost and a runtime key for production or staging sites.
  2. The Runtime Key controls how your app works on a website (with encoded domain in the key). This applies to production and staging (test) sites.
  3. Staging (test) sites will have a watermark. This is expected & by design. Production sites will not have a watermark.
  4. Development activity carried out on your local PC will require an activated developer license.
tip

Full instructions how to activate developer licenses, how to add production & test domains to your account and how to include Runtime keys can be found at scichart.com/licensing-scichart-js.

Resolving Wasm errors on load​

If you get an error when loading a SciChartSurface as follows:

warning

Error: Could not load SciChart WebAssembly module. Check your build process and ensure that your scichart2d.wasm, scichart2d-nosimd.wasm and scichart2d.js files are from the same version
