Your data contains a large number of null values at start and end. The property 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 '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!

from echarts.

it also can not display the last point which the date at 2022-09-26.

The last point is displayed. Only if you zoom into the area which contains null values the line is not shown which can be fixed with filterMode: 'none'.

Did you apply the suggestions i gave?

yes ,i try.If I'm not mistaken i think What you mean is to add a configuration filterMode: 'none'， I fixed the example. https://codepen.io/FriendsA/pen/VwNZxmw

it is still lost last point to me.

You just cant hover over it in the small view (since there are more data points than pixels). If you increase the width or zoom in you will see that it is present.

yes，but just on both sides has，so i think it is a bug. anyway, your help is greatly appreciated！

I dont understand, sry.

I dont understand, sry.

what I mean is that this phenomenon only appears at both ends of the chart. It should be a bug.

from echarts.

It does not only appear on both ends. If you hover through the data the tooltip will skip a lot of points

from echarts.

#main {
width: 1500px;
height: 400px;
border: 1px solid red;
}

因为描点太多，宽度像素不够，会导致tooltip跳过某些点导致显示不出来，把宽度调宽点就可以了。
