@jpc98 This issue looks like it can be solved by nesting your data inside a <VictoryChart>
component that also uses <VictoryVoronoiContainer>
as the value of the containerComponent
prop. Then you can manually use <VictoryTooltip>
as the labelComponent
prop of your data viz of choice. This should allow for a mouse to move from data point to tooltip without the tooltip disappearing.
<VictoryChart domainPadding={{ y: 10, x: 20 }}
containerComponent={
<VictoryVoronoiContainer/>
}
>
<VictoryBar
data={sampleData}
labels={() => "HELLO"}
labelComponent={
<VictoryTooltip
center={{ x: 225, y: 30 }}
pointerOrientation="bottom"
flyoutWidth={150}
flyoutHeight={50}
pointerWidth={150}
cornerRadius={0}
/>
}
/>
</VictoryChart>
Thanks for the suggested solution! This feels more like a workaround to me, and it may be worth considering making this feature standard for victory's tooltips rather than relying on consumers to implement a VoronoiContainer for the tooltips to meet the standard. But definitely lower priority since there's a way around it!
I wonder if it may be best to control this behavior with a prop, maybe something like a persistent
prop on the Tooltip component. The reason being that if a chart has a lot of points of interest, it may be desired behavior for the tooltip to vanish if the mouse moves off the data point. Making it standard by default could cause problems for existing users who upgrade
Maybe an override would make sense, but I do think we'd want the default to be meeting the accessibility guideline if at all possible, since that's the reason that guideline exists in the first place! The tooltip vanishing may be desired behavior, but it's also a problematic behavior for users using certain kinds of assistive technology.
That said, I realize this is the sort of change that could lead to a worse experience for certain use cases, so an override of some sort would make sense as long as the accessibility implications were documented. That way the site still behaves as originally intended until a more accessible design can be implemented without making the application difficult to use.

Description
The WCAG guidelines have the following criteria for hover bubbles: https://www.w3.org/TR/WCAG21/#content-on-hover-or-focus Relevant text quoted below:
This is not met by the hover tooltips provided by VictoryChart currently - when hovering over the content that pops up, the content disappears since the user is no longer hovering over the relevant point.
