Please try the latest subversion trunk first. A lot of things have changed, it 
might include a fix for this problem.

So I checked trunk in rev. 169. This is still not supported. The problem in 
solving this problem is that markers are implemented as an independent graph 
type, so in my opinion it could be bad idea to implement them to know about 
other graph types (i think about stacked bars charts). Of course if developers 
have other opinion i will be pleased to read it, and than i can try to think 
about solution. 

One temporary solution that I thing could work is to provide individual data 
series for markers, where as y value you can provide sums used in stacked bars.

Actually I fixed it in my local copy at line 3423 with:

var markerOffset = 0;
if(series.bars.stacked) {
    $H(xa.values).each(function(pair) {
        if (pair.key == x && (y > 0)) {
            markerOffset = pair.value.stack || 0;
            yPos = ya.d2p(markerOffset);
        }
    });
}

Just before the plot function.

@ohhohe: Hi, where is line 3423? I looked in 
http://code.google.com/p/flotr/source/browse/trunk/flotr/flotr/prototype/flotr.j
s#3423
and it does not look right

There are two different types of stacked charts, both behave in different way 
with negative values. "Stacked Bars" like charts sum negative and positive 
values independently (this only reasonable way for bar charts i think). 
"Stacked Area" like charts shows exact sum, so negative and positive values are 
summed together.

Having this in mind, there should be option in stacked markers to specify which 
type of summing should be used.
