Hello JP, thanks for creating this tool !
I have a few questions though : I try to edit the JS code from this page https://bl.ocks.org/mbostock/4063423 in order to create a custom Sunburst data chart. I have imported the JSON sample file this page gives, and modified a few things in the JS code to try and adapt it, changing FROM :
var width = 960,
height = 700,
radius = Math.min(width, height) / 2,
color = d3.scale.category20c();
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height * .52 + ")");
var partition = d3.layout.partition()
.sort(null)
.size([2 * Math.PI, radius * radius])
.value(function(d) { return 1; });
var arc = d3.svg.arc()
.startAngle(function(d) { return d.x; })
.endAngle(function(d) { return d.x + d.dx; })
.innerRadius(function(d) { return Math.sqrt(d.y); })
.outerRadius(function(d) { return Math.sqrt(d.y + d.dy); });
d3.json("flare.json", function(error, root) {
if (error) throw error;
var path = svg.datum(root).selectAll("path")
.data(partition.nodes)
.enter().append("path")
.attr("display", function(d) { return d.depth ? null : "none"; }) // hide inner ring
.attr("d", arc)
.style("stroke", "#fff")
.style("fill", function(d) { return color((d.children ? d : d.parent).name); })
.style("fill-rule", "evenodd")
.each(stash);
d3.selectAll("input").on("change", function change() {
var value = this.value === "count"
? function() { return 1; }
: function(d) { return d.size; };
path
.data(partition.value(value).nodes)
.transition()
.duration(1500)
.attrTween("d", arcTween);
});
});
// Stash the old values for transition.
function stash(d) {
d.x0 = d.x;
d.dx0 = d.dx;
}
// Interpolate the arcs in data space.
function arcTween(a) {
var i = d3.interpolate({x: a.x0, dx: a.dx0}, a);
return function(t) {
var b = i(t);
a.x0 = b.x;
a.dx0 = b.dx;
return arc(b);
};
}
d3.select(self.frameElement).style("height", height + "px");
TO :
var width = pbi.width,
height = pbi.height,
radius = Math.min(width, height) / 2,
color = pbi.colors();
var svg = d3.select("#chart")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height * .52 + ")");
var partition = d3.layout.partition()
.sort(null)
.size([2 * Math.PI, radius * radius])
.value(function(d) { return 1; });
var arc = d3.svg.arc()
.startAngle(function(d) { return d.x; })
.endAngle(function(d) { return d.x + d.dx; })
.innerRadius(function(d) { return Math.sqrt(d.y); })
.outerRadius(function(d) { return Math.sqrt(d.y + d.dy); });
pbi.dsv(function(root) {
var path = svg.datum(root).selectAll("path")
.data(partition.nodes)
.enter().append("path")
.attr("display", function(d) { return d.depth ? null : "none"; }) // hide inner ring
.attr("d", arc)
.style("stroke", "#fff")
.style("fill", function(d) { return color((d.children ? d : d.parent).name); })
.style("fill-rule", "evenodd")
.each(stash);
d3.selectAll("input").on("change", function change() {
var value = this.value === "count"
? function() { return 1; }
: function(d) { return d.size; };
path
.data(partition.value(value).nodes)
.transition()
.duration(1500)
.attrTween("d", arcTween);
});
});
// Stash the old values for transition.
function stash(d) {
d.x0 = d.x;
d.dx0 = d.dx;
}
// Interpolate the arcs in data space.
function arcTween(a) {
var i = d3.interpolate({x: a.x0, dx: a.dx0}, a);
return function(t) {
var b = i(t);
a.x0 = b.x;
a.dx0 = b.dx;
return arc(b);
};
}
d3.select(self.frameElement).style("height", height + "px");
Multiple problems then happen :
1- The D3 chart remains blank, although I tried many changes in the JS code
2- When I go back to report to visualize the chart and I go back to editing, the JS and CSS code disappears, only pbi remaining : and when I hit 'Save' when in pbi editing, the CSS code comes back but the JS code is replaced by the pbi code !!!
I don't know if it's a JS mistake of mine or something other users experienced, but if you'd give me a hand, I would really appreciate it !
