Please try subversion trunk first. If that doesn't provide the function, please 
port your patch so it applies cleanly to that version.

Let me know how it goes.

I applied mab's patch to the last revision from trunk, i have followed #rev176 
and added caching of d2p() values.

I've noticed some problems with stacked line charts.  I have attached two 
sample files to this issue.  Tested with flotr-svn r182.

chart-stacked.html contains 4 data series, three with stacked:true,fill:true 
and one with stacked:false,fill:false.  Each of the three stacked data series 
has the same data values.

chart-nostacked.html replicates chart-stacked.html and emulates stacked 
behaviour by progressively adding the values of the lower data series at each 
data point on the x-axis.

The chart in chart-nostacked.html shows properly, while the chart in 
chart-stacked.html goes above the top of the chart area.  Both charts should 
look approximately identical (disregarding colours).

The mouse tracking also only appears to work on the first (green) stacked data 
series in chart-stacked.html.  Mouse tracking also works fine for the unstacked 
blue line.  There are no problems with mouse tracking on the chart in 
chart-nostacked.html.

Ok, so to be precise. Mouse tracking for stacked line graphs is not implemented 
yet so it works like for normal - not stacked lines. I will think about this in 
the future. 

About chart area - yes you are right, i will investigate this as soon as 
posible, probably there is a problem with my function to calculate ploting 
range.

I have committed a solution for your problem with chart area. Let me know if 
that helped. Solution is in revision r185

Thanks.  I tried r186 and I got it working, after a few problems.
I could only get it to display properly when putting lines:{show:true;} into 
the options object (third argument passed to Flotr.draw).  It didn't display 
properly if I removed that from the options object and only had it on each 
individual dataset in the chart data object (second argument passed to 
Flotr.draw).

Ok, I will investigate this too.

Thanks.  You can replicate the bug by taking chart-stacked.html from Comment 
#12 and removing "show":true from the lines{} object, and then adding 
lines:{"show":true} to each object in the chartData array.
