D3 Only Loading One Cell of Data

Question

I have a http.server running on my 8888 port using python.

I am attempting to a load tsv file into the Day/Hour Heatmap: [a link] http://bl.ocks.org/tjdecke/5558084#data.tsv

Note that both the data.tsv file and the code

The output below is what I'm seeing in my Chrome browser when navigating to the appropriate file. It is not loading the full amount of data.

The code looks right and since its exactly the way it is shown in the example, the problem might be with your data file. Getting data only in the first grid means your x and y values are not getting properly rendered. .attr(" x ", function(d) { return (d.hour - 1) * gridSize; }) .attr(" y ", function(d) { return (d.day - 1) * gridSize; })

Are the names day and hour correctly written? (even caps creates problem - something like Day and Hour instead of day and hour)

Hope this helps.
