Showing a hidden column in tooltips

[dunba...@gmail.com]

Hi, 

I am using a line chart with multiple series, and am using the last column of the dataTable to store the totals at each time point. I use a dataView to stop the totals column from displaying with the rest of the data. 

What I would like is to show the total for each time point in the tooltip, at the top of the panel of values that you get with the chart option focusTarget: "category", crosshair: { trigger: "focus" }

How do I go about doing this? 

All help appreciated.

There is no direct support for such a display, but you could probably create it with sufficient hacking.  Here are a couple hints if you want to pursue it.  You'll have to create your own html overlay at the right position based on where the mouse is (and thus the crosshair would be). You would need access to the corresponding total value, which you could look up in your original data table.

Hi Dan, 

Thanks for getting back to me. 

Do you think I could do it using a showFullTooltip() function, in the same way that can be done in Treemaps? 

The trouble with the Overlay approach is that I have to create DIV classes for the elements, and I already have a page with a lot of containers carefully balanced together which I would prefer to leave untouched. 

Regards, 

Nick

The undocumented generateTooltip option (which you could use with a showTooltip function) is only available for the Treemap so far, but it would be a good idea to support something similar elsewhere.
