Re: Fast spectrogram

Thanks for the info.

yes could you provide a sample? That would be great.
I must not be a line graph but the performance should be as fast as possible.

Re: Fast spectrogram

Hi,

I want to have the highest updaterate being possible.
That means the spectrogram should be updated 5 - 10 ms per spectrum data (200 points).
Competitor sample browser shows that this is possible.
I think your framework can do this as well.

BR,
Hendrik

Fast spectrogram

Hi,

can you give me a sample solution for the fastest spectrogram (line) being possible
when using LighningChart?

The demo app is too slow and maybe full of unnecessary code lines to achieve this.

Thanks,
BR,

Update assembly versions to Nuget server

Hi,

is it possible to update your Nuget packages to all available versions? The latest Nuget assembly version is 6.5.8 being from March.
I want to update this to my last possible version 7.1.2 because we use build servers to generate installers for our app.

BR,

Re: Persistent spectrum

Hi, I downloaded the new API for v7. I saw your sample browser. The sample "ExamplePersistentFFT" seems to have the feature to zoom and resize the chart without resetting the persistent chart. This is what I want actually. The sample "ExamplePersistentRenderingHighLowAreas" on th...

Re: WPF Charts displays blank on Remote Desktop

Hi,

I got the same problem with remote desktop to Win 7 maschine, the chart is completley blank. Your demo is also affected. Nothing to complain for Win 8 Remote Desktop.
If I check the GPU info for your app, every value is no or "-".

What can I try to solve the problem?

Re: AudioOutput, how does it work

Hi,

that helped me allot. Thanks for that. I seems that the sound is looping all the time. Can I avoid this behavior that the sound will only play If new data is added?

Thanks.

Re: Persistent spectrum

Hi, thanks for the clarification. How can I present the decay factor to the user? If I have no decay the color code will be fine but if I use the a certain decay there will be a changed color code isn't? I read in your docs that there will be an automatic reset of the chart on resizing it. This is n...

Re: Persistent spectrum

Hi, thanks for the response. Ok if I have my color range from 0...100 then I will have my maximum hit count at 100. With a NewTraceIntensity = 1 and HistoryIntensityFactor = 1 my assumption from my first post is then the same. If I have a spectrum data set varying only at one index occuring every se...

Hi, I want to use your PersistentSeriesRenderingIntensityLayer with a HighLowSeries. I do not understand, how the Colors are mapped to the incomming spectrum data sets. Let's assume the following: - A probability range from 0...100 where 100 is the highest probability of occurence for one data point...
