remove or skip null values in d3js stacked bar chart - d3.js

Question

I have a data object to show stacked bars with an initial animation that plays upon loading the page, essentially where fruits correspond to orchards:
[{Apple=1.0, Orange=2.0, Lettuce=1.0, orchard=小明, Blueberry=1.0}, {Apple=1.0, Orange=1.0, Lettuce=1.0, orchard=小陈, Blueberry=1.0}, {Apple=1.0, Orange=1.0, Lettuce=1.0, orchard=小虎, Blueberry=1.0}, {Orange=1.0, Lettuce=1.0, orchard=小桃, Blueberry=1.0, Apple=1.0}]
The below code works fine if each orchard includes every fruit-type, but upon let's say removing Apples from everyone except for 小明, the y0 values for multiple orchards become 'NaN'. I am asking for a way to remove NaN values or find a way to skip them in d3js so that other fruits can still be displayed.
My rectangle code can be found below:
var rect = groups.selectAll("rect")
.data(function(d) { return d; })
.enter()
.append("rect")
.attr("x", function(d) { return x(d.x); })
.attr("height", function(d) { return y(d.y0) - y(0); })
.attr("y", function(d) { return y(0); })
.attr("width", x.rangeBand())
.on("mouseover", function() { tooltip.style("display", null); })
.on("mouseout", function() { tooltip.style("display", "none"); })
.on("mousemove", function(d) {
var xPosition = d3.mouse(this)[0] - 15;
var yPosition = d3.mouse(this)[1] - 25;
tooltip.attr("transform", "translate(" + xPosition + "," + yPosition + ")");
tooltip.select("text").text(d.x + ": " + d.y);
});
svg.selectAll("rect")
.transition()
.duration(800)
.attr("y", function(d) { return y(d.y0 + d.y); })
.attr("height", function(d) { return y(d.y0) - y(d.y0 + d.y); })
.delay(function(d,i){console.log(i) ; return(i*90)});
I am curious about using something like
rect.filter(function(d) {
return d.y == 0;
})
.remove();
But this does not seem to work. Unfortunately I am using d3js v3.

The issue was solved by reformatting how my d3 viz read keys. In my answer to my other question you can see how the keys variable was reformatted.
I don't have my v3 version saved on-file, but it had something to do with how stackedLayout works in v3. Not sure, but if you have a similar issue, I suggest reformatting how your variables are stacked to follow the same philosophy of using
.data(d3.stack().keys(keys)(data))
