I cannot map the sinelon effect into the matrix about esp8266-fastled-iot-webserver

Sorry for the late response. I would have coded like this instead of using the XY helper function:

    for (uint8_t y = prevpos; y <= pos; y++) {
      for (uint8_t x = 0; x < LEAFCOUNT; x++) {
          for(int i = 0;i < LEDS_PER_LEAF;i++)
             leds[LEAFCOUNT * LEDS_PER_LEAF + i] = color;
    }

    }

i tried yours but it cant work. there is blank effect. this is my code:

{
  // a colored dot sweeping back and forth, with fading trails
  fadeToBlackBy(leds, NUM_LEDS, 20);
  int pos = beatsin16(speed, 0, NUM_LEDS);
  static int prevpos = 0;
  //CRGB color = CHSV( gHue, 255, 192);
  CRGB color = ColorFromPalette(palettes[currentPaletteIndex], gHue, 255);
  for (uint8_t y = prevpos; y <= pos; y++) {
      for (uint8_t x = 0; x < LEAFCOUNT; x++) {
          for(int i = 0;i < PIXELS_PER_LEAF;i++)
             leds[LEAFCOUNT * PIXELS_PER_LEAF + i] = color;
    }
  }
 prevpos = pos;
 delay(1000 / FRAMES_PER_SECOND );
}

I don't know if you got this working, but this seems to do it for me.

void sinelon_leaf()
{
// a colored dot sweeping back and forth, with fading trails
fadeToBlackBy(leds, NUM_LEDS, 20);
int pos = beatsin16(speed, 0, LEAFCOUNT);
static int prevpos = 0;
CRGB color = ColorFromPalette(palettes[currentPaletteIndex], gHue, 255);
if (pos < prevpos) {
pos *= PIXELS_PER_LEAF;
fill_solid((leds + pos), (prevpos - pos) + PIXELS_PER_LEAF, color);
}
else {
fill_solid(leds + prevpos, (pos - prevpos) + PIXELS_PER_LEAF, color);
}
prevpos = pos;
delay(100);
}

I added it as an extra pattern.
