plotLine fails on Safari

[GoogleCodeExporter]

When I send too many points to a line plot in Safari (more than 10000), my page 
refreshes and then fails to load.
I think the issue is related to the ctx.stroke() failing at the end of the 
function
I patched it by limiting the number of points before a stroke() to be an 
arbitrary amount (a parameter I use to set to 5000) and now it works.
It would be great to have this one, or a better solution, in the official code.

Regards
Ce

This is a problem in excanvas as well.  It sounds like Flot should have a 
generalized system of splitting very large lines into smaller ones.

Ce, could you explain how you patched the code? I'm having the same problem.

Thanks!

Dear Ruby, 
I'm sorry but I'm not a javascript developer so, as far as I can remember, I 
just plugged some code in.
Moreover, I'm not directly using flot anymore (note: flot is great and I 
strongly recommend it, it is just that I am not developing for the web now). 
Anyway, the code addition is about 10 lines, all confined in the 
drawSeriesLines(series) function (the only I used, sorry, I know it sounds 
really lazy). You'll find starting and closing comments like "modified by cesco 
...".
It is just a trivial windowing mechanism and maybe it could be implemented in 
several better ways or just improved by parametrizing the chunk variable and 
extending to other drawing methods. I agree with David but don't look at me for 
such a coding ;)
I attached the complete code for drawSeriesLines so I think you just need to 
copy and paste it over the original one.

Hope this helps
Ce
