This section makes an axis.The axes in D3 are in the form of SVG diagrams, which is why the method of SVG is used in the 3rd section to do column charts. In the 4th section, we

In a blink of an eye, this introductory series has accumulated more than 22 articles, I think as d3.js this data visualization tool is enough to get started. I believe that as long as you finish this series, you can complete most of the visualization work in the case of query.The earlie

form, that is, to define a nameless functions function (d,i), and then use D and I in the implementation of the function. D3 also has a feature that enables the bound data to be passed to child elements. Make a slight change to the previous code:P.datum ("Thunder"). Append ("span")//Add element Span.text after each selected element (function (d,i) {return "" + D;});As shown in result 4, the span element is added at the end of each paragraph element,

) .. attr(' height ', function(d) { return - yscale(yaccessor(d)); }) You can put a constant or function in every attr, this time you use the scale, you give your scale a y-axis value of the parameter, he returned to you a corresponding length.The same x and y coordinates can be calculated as well. . attr(' x ',function (d) { return XScale(xaccessor(d)); }) . attr(' y ', function (d) { return yscale(yaccessor(d)); }) If y

Data. Enter (). Append ("text"). attr ("Font-size", " 10px "). attr (" X ", function (d,i) {return i * RECT_STEP;}). attr ("Y", function (d,i) {return max_height;}). attr ("DX", RECT_STEP/2-8). attr ("dy", "15px").

First make a dynamic column chart (the version of D3.js used here is V3, some functions will change with V4)：Code:Now add the mouseover and mouseout events like this dynamic column chart.Practice:1. Remove the style from the style. MyText class that adds a color attribute directly when adding a rectangle2. Add an event when adding a rectangle...//adding rectangles and text elements varrectpadding = 4; va

to the data of two vertices.Well, with this data, we can make a drawing. We use the line in SVG to draw edges and draw vertices with circle in svg.var svg_edges = Svg.selectall ("line"). Data (Edges). Enter (). Append ("line"). Style ("Stroke", "#ccc"). Style (" Stroke-width ", 1); var color = D3.scale.category20 (); var svg_nodes = Svg.selectall (" Circle "). Data (nodes). Enter (). Append ("Circle"). attr ("R", "Ten"). Style ("Fill", function (d,i)

Append (" Circle "). attr (" CX ", function (d) {return d.cx;}). attr ("Cy", function (d) {return d.cy;}). attr ("R", function (d) {return D.R;}). attr ("Fill", "Black").

displayed. Intuitively, the function of the layout is to transform some data into another data, and the transformed data is beneficial to the visualization. Therefore, the tutorial on this site is called the layout "Data transformation."Of course, you can also follow the original word "layout" to understand, but also can be understood as "calculation", as long as you know the meaning.Thank you for reading.Document Information Copyright Notice: Attribution (by)-Non-commercial (NC)-No de

Click "OK".(4) After saving successfully, open with Notepad, the result is as follows:In D3.js, a function that reads a CSV file only supports separating cells with commas, so be sure to save them like this.3.
