Hi @h4h13, this is my trick:
If you use BarGraphRenderer, you can change height of bars(in my case increase 5 times for bottom bar):

` @OverRide
public void onRender(Canvas canvas, FFTData data, Rect rect)
{
for (int i = 0; i < data.bytes.length / mDivisions; i++) {
mFFTPoints[i * 4] = i * 4 * mDivisions;
mFFTPoints[i * 4 + 2] = i * 4 * mDivisions;
byte rfk = data.bytes[mDivisions * i];
byte ifk = data.bytes[mDivisions * i + 1];
float magnitude = (rfk * rfk + ifk * ifk);
int dbValue = (int) (10 * Math.log10(magnitude));

  if(mTop)
  {
    mFFTPoints[i * 4 + 1] = 0;
    mFFTPoints[i * 4 + 3] = (dbValue * 2 - 10);
  }
  else
  {
     //PhamVanKha increase bar height 5 times
    mFFTPoints[i * 4 + 1] = rect.height();
    mFFTPoints[i * 4 + 3] = rect.height() - (dbValue * 2 - 10) * 5;
  }
}

canvas.drawLines(mFFTPoints, mPaint);

}`
