google charts - modify tooltip hide/show time

[little...@gmail.com]

Is there a way to set fadeIn/ fadeOut time for the tooltips displayed in the google chart? 

I have one tooltip which contains a scroll bar and; need to scroll down to see data in the tooltip before it disappears.

Thanks.

You can't set the fade in/fade out time, but you can set the tooltip.trigger action to "selection", which will spawn the tooltip when the user clicks the associated data point, and the tooltip will stay in place until they click another point.  Being able to control the fade values would be quite helpful, so I suggest that you file a feature request to add support.

Thanks asgallant for your answer.

I've filed an enhancement request for the feautre: "Issue 1301: Add fadeIn/ fadeOut [hide/show] time property to tooltip on google charts".

I was able to implement what you suggested but I miss what I have lost. Though I am able to scroll in one of the tooltips but now I have to click on every data point whenever I need to know something about it. Can you suggest something? I'll explain my problem:

On a chart, I am displaying some tooltips. Now, data in some of these tooltips is large such that in some cases it bumps off the chart DIV. The UI does not look good, so; I introduce a scroll bar in the tooltip. After making the tooltips dependent on click, I loose the functionality of easily going over the chart and seeing the values by hovering (no selection) but gain the ability to scroll data in the other tooltips. I would like to regain the hover utility along with scroll. Guess I am being greedy.

Any other alternative?

Thanks.

Little,

It sounds like what you really need is that if the user hovers over the tooltip, it remains visible as long as they stay inside the area of the tooltip, or maybe if they exist for a short time and return.  A fadeOut time by itself would not necessarily support that very reasonable feature.  This is more of a delay before starting a fadeOut, but also a disabling of the fadeOut while you are still hovering, either over the data point or the associated tooltip.  And maybe there would have to be a similar delay before showing a tooltip.

I don't know how difficult it will be to support this delay/disable feature in the current code, or if it will have to wait until we do more restructuring of the event handling, but we'll look into it.  Thanks for your suggestion.
