I’ve the following problem.
We have an application where we have many spectrums (frequency or order spectrums). To get a better overview and to select one for a more detailed analysis, we would like to display them as a waterfall chart. A spectrum always has a high resolution of 32768 points. If I now display between 60 and 100 spectrums in a waterfall chart, it takes quite a long time to render this and it is almost impossible to operate the chart.
However, a high-resolution spectrum is not required for a good overview in the waterfall diagram. Therefore my idea is to resample every single spectrum to e.g. 8192 points and then display it in the waterfall diagram.
Is there a possibility to use the internal SciChart resampler (e.g. Min/Max) or do I have to develop an own algorithm for this?
Or does a similar function already exist in SciChart?
We have a sample actually in our Github repository that does exactly this. It creates a Waterfall 3D Chart and has many slices, each with 65,000 points.
Let me know if this helps!
thank you very much! The example fits perfectly and also works in my code immediately and without problems.
One thing I noticed. If I replace the obsolete PointResamplerFactory by the ExtremeResamplersFactory
I get an exception, because there is 1 more value in the Y-values than specified in the property Count.
I have attached a screenshot of your example with the exception.
I don’t know if I am doing something wrong or if this is a bug from SciChart.
