I am considering applying server-side licensing for my javerScript application.

In the document below, there is a phrase “Our server-side licensing component is written in C++.”
(https://support-dev.scichart.com/index.php?/Knowledgebase/Article/View/17256/42/)

However, there is only asp.net sample code on the provided github.
(https://github.com/ABTSoftware/SciChart.JS.Examples/tree/master/Sandbox/demo-dotnet-server-licensing)

I wonder if there is a sample code implemented in C++ for server-side licensing.

Can you provide c++ sample code?
Also, are there any examples to run on Ubuntu?

    Sounds good. I’ll need to get a small solution that can reproduce this outside our product solution. My first attempt was a simplified version and didn’t reproduce the same behavior. It might take me a bit to get that reproduction outside the product. Thanks for the prompt response!

    Is it possible to give you to debug the issue with our compiled binaries (running against your debug dlls)? If not that is fine–I’m still working on moving the simple side example towards our actual code until the behavior shows itself.

    Also emailed zipped solution as well.

    Also added another attachment that depicts a similar bit at the end of a signal (that ends with the bit being on).

    Another update that I forgot to add — This issue doesn’t seem to happen on the HighSpeedRenderSurface. But does on the HighQualityRenderSurface — This may be a key to tracking it down. Do note that secondglitch.png (https://abtsoftware-wpengine.netdna-ssl.com/wp-content/sabai/File/files/l_f1e47e8d6763d8e945f631c041ecf565.png) still happens regardless of the render surface.

Hi Riley,

We have a cluster of bugs reported related to Digital line and certain patterns of data, which we are looking into. Thank you so much for your sample, I will tag it onto the bug that we are working on.

When we have an update I will let you know.

Best regards,
Andrew

    Thanks!

    Has a fix found its way into any of the recent builds? Is there a status or some issue that I can see where this is at?

    Hi Riley, on investigation this isn’t a bug in Digital Line, but how the lines render with the HighSpeedRenderSurface. By default all lines in SciChart have a round line pen cap, so if you go from thin to thick line it will look like the edges are rounded. The best way around this is, is to use another series type to go from thin to thick line. You could use Band Series, a combination of MountainSeries and LineSeries, or create a custom series for which there is documentation here: https://www.scichart.com/documentation/v5.x/webframe.html#Custom%20Series%20(CustomRenderableSeries).html
