> Your data contains a large number of `null` values at start and end. The property [connectNulls](https://echarts.apache.org/en/option.html#series-line.connectNulls) interpolates the line if **inbetween** two datapoints there are `null` values. In Your case there is no datapoint to connect to in the beginning. You could add an auxiliary point at the beginning to combat that. Additionally, when zooming in, all data points outside of the view are filtered out which leads to the same problem. You can add [filterMode](https://echarts.apache.org/en/option.html#dataZoom-slider.filterMode) `'none'` to not filter out data but this will slow down performance. thinks for your help! you can hidden the line which have `null` data and leave the other complete line only，it also can not display the last point which the date at 2022-09-26. I want it can display last point on chart! -- This is an automated message from the Apache Git Service.
