Hello,
I am new to D3.js and I had trouble laying two SVG Treemaps on one page.
I got a hint from this.
What I want to do is lay two zoomable treemap elements on one page. (The sample above is for one treemap.)
I implemented the code myself, but not working properly.
Please help me if you are familiar with SVG and have experience with the zoomable D3 treemap.
chart1.js
fetch('../data/chart1.json') .then((response) => response.json()) .then((json) => { render(json, 'investicija'); render(json, 'proizvod'); }) .catch((error) => console.error('Error fetching data:', error)); function render(treemapData, selector) { const renderData = treemapData[selector][0]; // Ensure this key exists in your JSON data (function () { const margin = { top: 20, right: 0, bottom: 0, left: 0 }; const container = document.getElementById(selector); const width = container.clientWidth; const height = container.clientHeight; let svg, grandparent, scaleX, scaleY, treemap; function createSvg() { scaleX = d3.scale.linear() .domain([0, width]) .range([0, width]); scaleY = d3.scale.linear() .domain([0, height]) .range([0, height]); treemap = d3.layout.treemap() .children((d, depth) => depth ? null : d._children) .sort((a, b) => a.amount - b.amount) .ratio(height / width * 0.5 * (1 + Math.sqrt(5))) .round(false) .value(d => d.value); svg = d3.select(`#${selector}`).append("svg") .attr("width", width + margin.left + margin.right) .attr("height", height + margin.bottom + margin.top) .style("margin-left", -margin.left + "px") .style("margin-right", -margin.right + "px") .append("g") .attr("transform", `translate(${margin.left},${margin.top})`) .style("shape-rendering", "geometricPrecision"); grandparent = svg.append("g") .attr("class", "grandparent"); grandparent.append("rect") .attr("y", -margin.top) .attr("width", width) .attr("height", margin.top + 10); grandparent.append("text") .attr("x", 25) .attr("y", 6 - margin.top + 3) .attr("dy", ".75em"); } function initialize(d) { d.x = d.y = 0; d.dx = width; d.dy = height; d.depth = 0; } function accumulate(d) { return (d._children = d.children) ? d.amount = d.children.reduce((p, v) => p + accumulate(v), 0) : d.amount; } function layout(d) { if (d._children) { treemap.nodes({ _children: d._children }); d._children.forEach(c => { c.x = d.x + c.x * d.dx; c.y = d.y + c.y * d.dy; c.dx *= d.dx; c.dy *= d.dy; c.parent = d; }); } } function display(d) { grandparent .datum(d.parent) .on("click", transition) .select("text") .text(selector); const g1 = svg.insert("g", ".grandparent") .datum(d) .attr("class", "depth"); const g = g1.selectAll("g") .data(d._children) .enter().append("g"); g.filter(d => d._children) .classed("children", true) .on("click", transition); g.append("rect") .attr("class", "parent") .call(rect) .style("fill", d => d.color) .append("title") .text(d => d.fullname); g.selectAll(".child") .data(d => { layout(d); return d._children || [d]; }) .enter().append("rect") .attr("class", "child") .call(rect); g.append("text") .classed("overlaidText1", true) .text(d => d.name) .call(middletext1); g.append("text") .classed("overlaidText", true) .text(d => d.text) .call(middletext); function transition(d) { if (!d || this.transitioning) return; this.transitioning = true; const g2 = display(d), t1 = g1.transition().duration(1000), t2 = g2.transition().duration(1000); scaleX.domain([d.x, d.x + d.dx]); scaleY.domain([d.y, d.y + d.dy]); svg.style("shape-rendering", null); svg.selectAll(".depth").sort((a, b) => a.depth - b.depth); g2.selectAll("text") .style("fill-opacity", 0); t1.selectAll("text:not(.overlaidText)").call(middletext1).style("fill-opacity", 0); t2.selectAll("text:not(.overlaidText)").call(middletext1).style("fill-opacity", 1); t1.selectAll(".overlaidText").call(middletext).style("fill-opacity", 0); t2.selectAll(".overlaidText").call(middletext).style("fill-opacity", 1); t1.selectAll("rect").call(rect); t2.selectAll("rect").call(rect); t1.remove().each("end", () => { svg.style("shape-rendering", "geometricPrecision"); this.transitioning = false; }); } return g; } function text(text) { text.attr("x", d => scaleX(d.x) + 6) .attr("y", d => scaleY(d.y) + 2); } function middletext(text) { text.attr("x", d => scaleX(d.x + d.dx / 2)) .attr("y", d => scaleY(d.y + d.dy / 2) + 18); } function middletext1(text) { text.attr("x", d => scaleX(d.x + d.dx / 2)) .attr("y", d => scaleY(d.y + d.dy / 2) - 3.5); } function rect(rect) { rect.attr("x", d => scaleX(d.x)) .attr("y", d => scaleY(d.y) - 6) .attr("width", d => { const x0 = scaleX(d.x); const x1 = scaleX(d.x + d.dx); const w = x1 - x0; console.log(`Width for ${d.name} in ${selector}: x0=${x0}, x1=${x1}, width=${w}`); return w; }) .attr("height", d => scaleY(d.y + d.dy) - scaleY(d.y)) .attr("rx", "0px"); } // Debug logs createSvg(); initialize(renderData); accumulate(renderData); layout(renderData); display(renderData); })(); }
