Vertical annotation with float values do not display

Hello there,

Made a new instance of issue #79, because that problem does exist. I ran into it to and I did some more investigation.

Turns out that this is caused by a function in the main repository which is called here: pixel = helpers.isValid(options.value) ? scale.getPixelForValue(options.value) : NaN;

The scale.getPixelForValue implementation has the following code:

var labels = me.getLabels();
value = valueCategory || value;
var idx = labels.indexOf(value);
index = idx !== -1 ? idx : index;`

Which as far as I can see it looks up the value (for instance 4.5) in the array of labels (for instance [1,2,3,4,5]) which of course fails.

So a solution would be to just do the calculations of the x-coordinate in this case in the plugin itself or get the function fixed in the main repository.

My bad, I needed to put the annotations in the “options” object. It works now.

Can you make a fiddle with the code you are using now? Maybe I can help
