I have a problem with the tooltips layout and the tooltip pointers

Posted by Joachim at 15:21 on Saturday 29th June 2024 [link]

hi,

With the new version the arrow of tooltips do not display correctly - e.g. outline is missing.
Poperty "tooltipsCssClass": "rgraph_tooltips" seems not to work as it did with 6.17.
Can you pls. check,
Thank you!

Can you post a minimal example that reproduces this please?

Hi,
I found that with v6.18 you append the canvas -id to "RGraph_tooltipsPointer". E.g. if your canvas is "my_cvs" then the id for the tooltips pointer is set to "RGraph_tooltipsPointer_my_cvs".
If the used css had settings for "#RGraph_tooltipsPointer" this will not be used any more.
How can you fix this?

The canvas ID was added to the tooltip ID to make it feasible to have different CSS for different charts' tooltips when you have multiple on one page.

If you're not bothered about this then you could make a slight alteration to your CSS selector and use a regex selector like this:

<style>
    div.RGraph_tooltip div[id^=RGraph_tooltipsPointer] {
        background-color: red !important;
    }
</style>

Or if you don't use any <div> tags in your tooltips:

<style>
    div.RGraph_tooltip div {
        background-color: red !important;
    }
</style>

I appear to have not mentioned this in the changelog - sorry about that!
