[BUG] Audio Analyzer sample crashes (EXC_BAD_ACCESS)


I’ve downloaded yesterday showcase example from your github:

After providing license key other samples work ok except Audio Analyzer (and the last sales dashboard – shows blank screen).

Problems is somewhere with SpectrogramSurfaceController ( If I commend it out wave plot and fft plot works)

Xcode shows there is some bad memory access at:
[SCIFastUniformHeatMapRenderableSeries internalDrawWithContext:WithData:]

Tested using:
iPhone 5SE
iOS 11.2.5
Xcode 9.2

    Hi Patryk, I’m able to reproduce the crash. Seems its the heatmap in the spectrogram demo. The heatmap in the main examples suite works fine. Working now for a resolution and will update you when done. Best regards, Andrew
