Make tooltips not show on connecting line between markers.

[bowofolaf]

 Hi,

 I have a combination chart with a line graph, with visible markers and i'm trying to disable the tooltips on the connecting lines. How do I go about this?

Hello Bowofolaf,

 Unfortunately this is not possible with the chart tooltips API. But it might be accomplishable.  First, make the mouse over property of all points call your js code.

chart1.AllSeries.Link.OnMouseOver =

"mouseover(this);";

 

Then, display your own tooltip using js:

<script type="text/javascript">function mouseover(item) {

if (item.shape == 'circle') {

//diplay tooltip code here

}

}

</script>

 Thanks Andre.

Can I use this to "do nothing" when the shape isn't the same as my set marker shape, and have the chartfx tooltips show otherwise (on my marker shape). Or does this completely override the chartfx tooltips(%v).

Thanks again.

The chart tooltip comes from the image map. chart1.AllSeries.Link.OnMouseOver changes the onmouseover event on the area of the image map. The tooltips changes the text property of the area of the image map (which most browsers use to display tooltip). So if you are going to use onmouseover, I would recommend that you turn off the chart tooltip.

Note: if your image marker is not circular, this might not work for you. Test the different markers and see what type of area they use on the source of the page.
