line chart with gap ?

[dms]

I have a web service that retrieves me data to draw a line chart; Basically, it retrieves me position and value.

The "problem" here is that I do have gaps between my positions (i.e. I have a lot of positions where the value is 0). For those positions without a value <= 0 assigned, I just don't send to d3 for performance  issues (I am working with huge amount of data and multiple charts).

Given that, how should I deal with gaps on line charts ? (I don't want my line chart to create an inexistent  line/conection between my line chart/data.

Any help ? insight ?

Thank you for your time.

Here is an example of line/area chart with gaps: http://bl.ocks.org/mbostock/3035090

Thank you Chris !

Sometime ago I'd seen this example, but trying to find it again yesterday wasn't easy !

Thank you very much for your time.

I do appreciate.

Cheers.,

That's the line that does all the trick:

.defined(function(d) { return d.y != null; })

but, are there a way of NOT sending positions with null values, so I avoid sending tons of null data to my visualization ?
