If I input the volume as 1, I get an error.

I don't want to use Volume

Set volumeHeightFactor: 0 to hide the volume portion.

InteractiveChart(..., style: ChartStyle(volumeHeightFactor: 0,...))

If set it to volumeHeightFactor: 0, the volume chart is not visible. But still...

List<CandleData> data = MockDataTesla.rawData
  .map((row) => CandleData(
  timestamp: row[0] * 1000,
  open: row[1]?.toDouble(),
  high: row[2]?.toDouble(),
  low: row[3]?.toDouble(),
  close: row[4]?.toDouble(),
  volume: 0,
  ))
  .toList();

An error occurs when volume input is zeroed.
