Tooltip isn't displayed when the first series is hidden

[rzds]

I only tested this on a stacked area chart. I used 2 versions of apexcharts.js:

• one from the CDN
• one that I downloaded from https://apexcharts.com/downloads/apexcharts-bundle.zip

CDN: I've noticed that only when you hide the first series (Series A in the example below) the tooltip doesn't show anymore.

Downloaded version: The tooltip shows but there is a problem on the first day of the interval because the x parameter in the formatter function is undefined.

tooltip: {    
        x: {    
            formatter: function (x) {
                if(typeof x==='undefined') {
                     return null;
                 } else {
                     return new Date(x).toCustomFormat();
                 }           
            }
        }
    }

Thanks for reporting.
Yes, since 1.4.11 - I see that the tooltip doesn't behave correctly when series is shown/hide with the legend interaction.

I will also test with the custom tooltip.x.formatter function which you provided.

Fixed it.

But couldn't reproduce the issue for tooltip.x.formatter which you mentioned. I don't get x = undefined when I hide the first series.

Please create a codepen with that issue so I can see what data you are using if the issue still persists after this patch.

Thanks for the fix.
I just checked and the version available for download (the one with the formatter bug) is 1.0.0. Way too old. Maybe someone could put a newer version on apexcharts site.

[junedchhipa]

No worries.
I will upload the latest version on the website.

[rzds]

Awesome.
Can you check it now with the latest version on cdn? Just go to "Sep 6" after you hide Serie A. You'll see there's no date displayed in that tooltip.

I did some more tests.
When I zoomed out this happens.

But when I move the mouse just a little...

Maybe this helps.

Indeed, it will help.
Thanks for providing extra details!
