I would like to create a level meter, maybe something like this:

I assume a bar chart, but am looking for suggestions.
BTW, I just switched from OxyPlot to SciChart, what a difference! I am so impressed!
Thanks,

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?

I have this so far: (Excuse the random garish colors)
Another issue, I have a frequency response plot:
For the response, I have a logarithmic x-axis, range 10 – 20,000.
I am missing the label at 20,000. How can I force that label?
Can I add x axis major grid lines at other x-values? A typical frequency response plot would have major grid lines at:
20, 50, 100, 200, 500, 1000, 2000, 5000, 10k, & 20k.
Thanks,

Hi Robert, beautiful VU meter and frequency response! :) The 20,000 label isn't shown as there is no major gridline at 20,000. To get this to show, you will need to override the AxisBase.TickProvider (overrides tick generation). We have an article on how to do this here: http://support.scichart.com/index.php?/Knowledgebase/Article/View/17201/30/advanced-tick-frequency-overriding Note that TickProviders are dynamic and update the ticks as you zoom. What I suggest you do is take one of ours as a basis and simply call the base method but also include VisibleRange.Max at the end of the array of ticks calculated by our provider. The base class you want is LogarithmicNumericTickProvider. Hope this helps!! Andrew
