In Meteor, how can I import data from a .tsv file to use in a d3.js chart?
Question:
Tag: javascript,d3.js,meteor
When I call a function like the following, the data object comes out undefined, and the chart won't render. How can I import this data using Meteor?
UPDATE: I'm trying out deps.autorun... as per this SO thread and @ethaan's answer below. This got my chart to render.
However, oddly enough, it renders with completely the wrong dataset. Very interesting... Here's the link to the current state of my project on github: https://github.com/goodwordalchemy/Reactive-line-graph-with-meteor/tree/master/barChart_pt2-meteor Check out waffles.tsv (changed name to distinguish from old file named data.tsv, which d3 seems to be loading).
And here is a screenshot of what's getting rendered: 
UPDATE II: As per this SO article I moved my data file into the public folder, and I am able to render my chart in the browser. However, The chart is not reactive. If I change the .tsv file, the data in the chart does not change....
Template.d3chart.rendered = function(){
// chart attributes and scale are defined up here...
var chart = d3.select(".chart")
d3.tsv("data.tsv", type, function(error, data) {
// callback function
}
}
Answer:
Template.d3chart.rendered = function(){
// chart attributes and scale are defined up here...
Tracker.autorun(function(){
var chart = d3.select(".chart")
d3.tsv("data.tsv", type, function(error, data) {
// callback function
}
})
}
Typo on rendered?, render dosn't exists
