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,

Style (" Fill ", Function ( d) {return color20 (D.source.index);}). Style ("opacity", 1). On ("MouseOver", function (d,i) {d3.select (this). Style ("Fill", "Yellow");}). On ("Mouseout", function (d,i) {d3.select (this). Tra

.scale.linear (). Range ([height, 0]);The range of Y and y2 (i.e. like Sugao) should be the same. We put the tick tag on the right side of the y2 so that it looks more symmetrical:Defining axes var Xaxis = D3.svg.axis (). scale (X). Orient ("bottom"). Ticks (5); var yaxis = D3.svg.axis (). scale (Y). Orient ("left"). Ticks (5); var y2axis = D3.svg.axis (). sca

particular state.2 drawing a simple Sankey diagram with D3D3 provides a Sankey plug-in that can be used to convert the data from the input node-connection to the intermediate data used by the Sankey diagram layout. These intermediate data can be easily combined with the SVG rectangle element ( rect ) to draw the node, combined with the path element ( path ) to draw the link. makes it convenient to draw Sankey diagram with D3. Figure 1 shows the drawi
