Frequently Asked Questions



All developers programming LightningChart API directly, need a license. Please see LightningChart EULA.

Charting developers (licensed) can generate a Deployment Key, and assign this Deployment Key to the source code of the project. Non-charting developers can’t see the charts in Visual Studio designer. If running the application with the debugger attached, the chart shows up, but with low-performance mode (~1 frame/sec), and shows a nag message. If development in Visual Studio designer or unrestricted usage while debugging is required, Developer license is needed.

Alternatively, you may want to consider getting a Floating license.

Yes. You can distribute LightningChart components with your software free of charge.

When you purchase a license you get:

  1. License keys
  2. Subscription for updates and technical support during the subscription period.

When the initial subscription expires, the license (and all the applications which you have deployed) keep working. You can continue developing with the latest LightningChart version released before the expiration date.

Subscription expiration ends technical support, updates and warranty. These services are extended by purchasing a subscription renewal.

No, our chart performance is real, and we don’t use these tricks like some other component providers. We don’t want to compromise signal quality. All data is stored in the series as it is given to it, and when you start zooming in, you can notice that all data is really there with full accuracy and quality.

Starting from LightningChart v.8 you can purchase the feature(s) which you need separately, or get a discounted package containing a combination of features. See all product options HERE.

Hard work, benchmarking and utilizing different technologies. For example, we use Direct3D, custom Intel Math Kernel, HLSL vertex and pixel shaders where they are the most efficient.

  • Saves you incredible amount of time and money. We have been developing LightningChart for years, full-time.
  • Allows your application to be available this year, not after several years.
  • LightningChart offers performance you most likely wouldn’t achieve yourselves.
  • Saves you from tangling with DirectX, with different level GPUs, and properties of them.
  • Saves you from tangling with Intel Math Kernel. It is all done already in LightningChart.

Yes, LightningChart supports Window handle management and the objects can be fully controlled with C++/CLI code. Please check the instructions from User’s Manual.

When deploying the application, setting the Deployment Key is needed. Refer to User’s Manual, chapters "License Management" and "Deployment."

Check that Arction.DirectXFiles.dll is deployed with your app. LightningChart checks if correct DirectX dll files are installed in the system, and if they are not, it reads them from Arction.DirectXFiles.dll the first time they are needed, and caches for future usage.
