In d3.js, you can zoom in on a path by using the zoom behavior and attaching it to an SVG element that contains the path. Here's how you can do it:
1 2 3 4 5 |
var zoom = d3.zoom() .scaleExtent([1, 10]) // Set the minimum and maximum scale levels .on("zoom", function () { svg.attr("transform", d3.event.transform); // Apply the zoom transform to the SVG element }); |
1 2 |
var svg = d3.select("svg") .call(zoom); // Attach the zoom behavior to the SVG element |
1 2 3 4 5 6 7 8 9 10 11 12 |
var path = svg.append("path") .attr("d", "M10 10 L50 50 L100 10") // Example path data .style("stroke", "black") .style("fill", "none"); // Define how the path should behave when zooming function zoomed() { path.attr("transform", d3.event.transform); } // Call the zoom behavior on the SVG element svg.call(zoom); |
With these steps, you can zoom in on a path in d3.js by applying the zoom behavior to an SVG element that contains the path.
