I'm trying to enable tooltips for Flot for Wordpress and am having problems with it when I add in a certain function and I need this to work from what I've tried to decipher onnline.
I downloaded the latest version of tooltips for flot charts and loaded the script when the plugin is loaded.
The chart I have create loads perfect when the following js code is not in the code or when the function is empty like below too.
Can anyone tell me what's wrong with the code that is stopping my chart appearing?
Cheers in advance, Alan.
This is code I believe I need to make the tooltips work
function showTooltip(x, y, contents) {
$("<div id="tooltip">" + contents + "</div>").css({
position: "absolute",
display: "none",
top: y + 5,
left: x + 20,
border: "2px solid #4572A7",
padding: "2px",
size: "10",
"background-color": "#fff",
opacity: 0.80
}).appendTo("body").fadeIn(200);
}
This is what works when I remove the inside of the code
function showTooltip(x, y, contents) {
position: "absolute"
}
Here full code below:
