Candlestick Large Data Change

"The original candlestick chart would become cluttered with data when dealing with large volumes of data and using the data zoom feature. The modification now is to switch between different time granularities (daily, weekly, monthly, yearly) when using data zoom. Once the limit of the last granularity is exceeded, it will switch to a line chart to address the issue of data density.
