Threshold plugin does not handle null values #688

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Threshold plugin does not handle null values - null values are used to separate 
line segments.

Sample HTML showing error attached.

Fix for code also attached - the null value needs to be inserted into both line 
segments.

The provided fix does not work if your point size (ps) is different than 2.  If 
that's your case, replace :

//push a null value into both series
threspoints.push(x);
threspoints.push(y);
newpoints.push(x);
newpoints.push(y);

with :

//push null values for both series.
for (j = 0; j < ps; j++) {
    newpoints.push(null);
    threspoints.push(null);
}

That way, no matter what's your point size, you will add enough null values.
