How can I request off-line activations for my license?
If online activation is not possible due to a lack of internet connection, licenses can be activated via e-mail. Request offline activation button becomes available in License Manager after the respective online action has failed once or twice. Off-line activation may require a day or two to be completed.
Arction guarantees the availability of activation service (on-line and off-line) during active subscription and 3 months after its expiry. After 3-months period has elapsed, off-line (manual) activations are subject to a fee, presented in Arction price list. On-line activations are always free of charge regardless of the subscription validity.
Can I get technical support during my trial period?
Yes, you can! Technical support is available by e-mail. Please contact sales.
Do non-charting developers need a license when working in a team?
All developers programming LightningChart .NET API directly, need a license. Please see LightningChart .NET 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 or a Site License.
Can I distribute LightningChart components royalty-free?
Yes. You can distribute LightningChart components with your software free of charge.
I can successfully install and run the SDK examples, but I don't have time to test the features myself in an application like mine. Can you provide a customized sample application or proof-of-concept?
Proof-of-concept and custom samples can be negotiated and included in LightningChart .NET license price.
What is the subscription?
When you purchase a LightningChart .NET 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.
Subscription can be renewed within 3 months after its expiration. After that, the full license price is applied. Please note that renewal extends a subscription from its expiration date.
Can I upgrade to a better edition, for example, from a subscription without source code to a subscription with source code?
Yes. Upgrading is possible. See the pricing page for additional details.
LightningChart is perfect for my application, but I would like to have a special feature added.
Please contact us in that case.
Does LightningChart .NET use data point reduction/resampling/decimation/down-sampling when rendering a line of high-speed signals or vast data sets?
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.
LightningChart is the only suitable data visualization component for our application, but the price is out of our budget. Can we get it with reduced price and without the features we don't need?
We have multiple package options to suit different needs, also you can contact sales to see if you are eligible for a special discount (eg. start-up or team discount). See all product options HERE.
What is the secret of LightningChart performance?
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.
Why use LightningChart instead of developing our own custom component from scratch?
– 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.
Our team includes several developers who need to use the Software at a different time. Can we get a Floating License for the team?
Yes, we also offer Floating Licenses besides standard Single Developer Licenses.
Floating License is granted for a selected period and can be used by any one developer member of Licensee’s team at a time. If several developers need to use the Software at the same time, you must get several floating licenses.
Please contact Sales for more information.
Can I use LightningChart .NET components in C++ applications (MFC / Win32)?
Yes, LightningChart .NET supports Window handle management and the objects can be fully controlled with C++/CLI code. Please check the instructions from User’s Manual.
Why users of our app see trial watermarks over the chart?
When deploying the application, setting the Deployment Key is needed. Refer to User’s Manual, chapters “License Management” and “Deployment”.
Why some of our users see the chart totally black?
Check that Arction.DirectXFiles.dll is deployed with your app. LightningChart .NET 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.
Does build server or build machine need a license key?
Starting from v.8, it does not. Ensure you have made a Deployment Key from a developer’s License key, and applied it in the code. Please note the debugging in such case, on the build machine, will enter the chart in low-performance mode.
What is the difference between different binding level editions of LightningChart .NET?
For WPF, LightningChart component is available in different binding level editions, to balance between different performance and MVVM (Model – View – View-Model) bindability needs.
As a general starting point, Arction recommends Semi-bindable API.
For best performance in WPF and multithreading benefits, select Non-Bindable chart.
|Chart edition||Properties binding||Series data binding||Per-data-point binding||Performance|
