d3.js

问题 I am using some d3 for visualization and decided to also use reactstrap. Basically clicking a circle in d3 will result in the reactstrap element Collapse to appear. I am not finding any luck with setState... I am doing all my react code in componenetDidMount(), inside of componentDidMount(), I have a function update(), and in update, I have a function called click, and when click triggers, it does: this .setState({ collapse: !this.state.collapse }); It doesn't work, and I lack the fundamental

问题 I'm using https://observablehq.com/@d3/zoomable-circle-packing as an example to try d3 and circle packing in angular. I have the data which seems to be hierarchical and I'm following along the code that's presented. However, my d3.hierarchy() is giving me strange results. For some reason, all d.x , d.y and r are all negative. I couldn't figure out why. I'm still reading some guides and books trying to understand if I can figure out how d3.hierarchy works to understand why the values are

问题 I am trying to set something up in D3 where I have an axis for some collection of datapoints. In the case of outliers for the datapoints, however, I'd like to put those outliers in a bucket on an axis. Is there a way that I could specify an "outlier tickmark" for the axis to serve as a partition for placing those datapoints? Example: [1,3, 7, 12, 2048] * * * * * --1--2--3--4--5--6--7--8--9--10--11--12--13--14--15--O-- This following is the current code I have. It seems to me that scales only

问题 I'm having problems generating a good looking family tree with Javascript. Requirements: Each child should be connected to two parents in the tree, not one as in some graphs I've like spouses to be next to each other in the tree (same vertical position) I'd like to organize the nodes by generation vertically, so that you can see people born in the same decade at a glance. One person can have multiple spouses over time, and children with each of them Parents and children can be added freely in

问题 I'm playing around with the d3 js tree layout. I was following this example. I was trying to add class attribute to each of the node. How can i add one class to the root node and a different class to children node. var treeData = [{ "name": "Top Level", "parent": "null", "children": [{ "name": "Level 2: A", "parent": "Top Level", "children": [{ "name": "Son of A", "parent": "Level 2: A" }, { "name": "Daughter of A", "parent": "Level 2: A" }] }, { "name": "Level 2: B", "parent": "Top Level" }]
