I'm able to generate the following graph using D3 areas:
I want to create the following animation. When the webpage loads, you see the first figure. Then, each of the areas morphs into a bar. Finally, I would like to allow users to toggle between the two figures by clicking "B" or "D".
I was able to add the buttons and the corresponding bars to my figure, but I'm having troubles figuring out how to do the animation. This is the code that I have right now:
HTMLWidgets.widget({
name: 'IMposterior',
type: 'output',
factory: function(el, width, height) {
// TODO: define shared variables for this instance
return {

I am converting some v2 code to v4 and I am stuck at this point. where does the x an y functions go for v4? Also is this the right way to create nested values? Thanks
d3.stack()
.offset(d3.stackOffsetSilhouette)
.value(function(d) { return d.values; })
.x(function(d) { return d.date; })
.y(function(d) { return d.value; });
var nest = d3.nest()
.key(function(d) { return d.key; });
var layers = stack(nest.entries(mainVal));
Edited to add full code. Everything has been migrated to v4 but I'm just not sure about that section since layers is returning as an empty array.

I have a scatter plot matrix for which I need a tooltip. I tried using the following code, but then, it gives me tooltips at random points and not at the exact cells.
Can someone tell me where am I going wrong ? Or is not possible to generate a tooltip for my data?

This is an interesting situation. It boils down essentially to element append order and mouse-events. First, let's fix the obvious. You want a tooltip on each circle, so you shouldn't be calling tip.show when you mouse over a cell, but on the circles:
cell.selectAll("circle")
.data(data)
.enter().append("circle")
.attr("cx", function(d) {
return x(d[p.x]);
})
.attr("cy", function(d) {
return y(d[p.y]);
})
.attr("r", 5)
.style("fill", function(d) {
return color(d.Chemotherapy);
})
.on('mouseover', tip.show)
.on('mouseout', tip.hide);
But you'll notice with this change, we don't receive the events on our circles. This is because svg.brush is placing a rect over each cell so that you can select with the extent, and it's receiving the mouse events. So to fix that we change the order of drawing to brush then circle:
var cell = svg.selectAll(".cell")
.data(cross(traits, traits))
.enter().append("g")
.attr("class", "cell")
.attr("transform", function(d) {
return "translate(" + (n - d.i - 1) * size + "," + d.j * size + ")";
});
// add the brush stuff
cell.call(brush);
// now the circles
cell.each(plot);
But we still have a problem. We've got one more rect on top of our circles, the frame rect. Since we don't care about mouse events on it just do a simple:
.style("pointer-events", "none");
Putting this all together:

The code below displays marker-ends on arrows/paths/lines as intended, but the color of the marker-end does not vary by line (i.e., it is always the same orange color, not the color of its respective line). I think the code is defaulting to the color assigned to the first field of my data(?). Any advice would be appreciated.

While you are creating an svg:marker for each line, you give them all the same id. When they are then used on your line elements, since they all have the same id you are only using one of them.
Simple fix, give them unique ids:
svg.selectAll("marker.brand")
.data(brands)
.enter().append("svg:marker")
.attr('id', function(d,i){
return 'end-arrow' + i; //<-- append index postion
})
...
svg.selectAll(".line")
.data(brands)
.enter().append("line")
.attr("class", "square")
.attr('x1', function(d) {
return x(-d.pc1);
})
.attr('y1', function(d) {
return y(-d.pc2);
})
.attr("x2", function(d) {
return x(d.pc1);
})
.attr("y2", function(d) {
return y(d.pc2);
})
.style("stroke", function(d) {
return color(d['brand']);
})
.style('marker-end', function(d,i){
return "url(#end-arrow"+i+")"; //<--use the one with the right id
})
....
Example here.
I need to design a streamgraph using d3.js and I started to experiment with the code hosted on GitHub. Since my dataset is expected to have a varying range between the minimum and maximum values for date (it can be a period of one month or several years), I decided to use multi-scale format for the ticks on my x-axis instead of fixing the format and interval into weeks, months, years, etc. For example, if I leave the tick format the same way it is given in the sample code on GitHub
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom")
.ticks(d3.time.weeks);
and if the range of dates in my dataset spans for several years, the legend of the x-axis becomes crowded and unreadable.
I tried to use multi-scale format, but the visualization will not be drawn and the Dev tool of my browser returns the following error:
d3.time.format.multi is not a function
I sincerely hope someone can suggest me a solution for this problem.
