How to remove front data when appending data?

[snoooopy-ch]

Hi, everyone.

I want to remove first data when I append data to apexchart tail because i want to move graph to left smoothly.

balanceCharts['BTC'].appendData([{ data: [{ x: moment().format('YYYY-MM-DD HH:mm:ss'), y: [80, 85, 30, 50] }] }]);

How can I remove it?
Thanks.
