Secondary state value is always 0.0

I've defined my KChartWidget as following:

KChartWidget(
                datas,
                chartStyle,
                chartColors,
                isLine: isLine,
                onSecondaryTap: () {
                  print('Secondary Tap');
                },
                isTrendLine: _isTrendLine,
                mainState: _mainState,
                volHidden: _volHidden,
                secondaryState: _secondaryState,
                fixedLength: 5,
                timeFormat: TimeFormat.YEAR_MONTH_DAY,
                translations: kChartTranslations,
                showNowPrice: _showNowPrice,
                //`isChinese` is Deprecated, Use `translations` instead.
                isChinese: isChinese,
                hideGrid: _hideGrid,
                isTapShowInfoDialog: true,
                verticalTextAlignment: _verticalTextAlignment,
                maDayList: [1, 10, 100],
              ),

No matter what secondary state I use, it is always 0. I've manipulated all possible properties, and for asks and bids even, I've generated random values but none of these made any change in the secondary state value.
P.S: I have zero financial knowledge about these values.

I think there is a problem with the data. Can you check your data?

I have checked the data. It is real world data and what ever it is, I think it cannot be zero all the time.
