javascript - Using D3 zoom in JavaFX Webview -

-

i have javafx webview renders graph (using d3). want implement 'zoom on mouse scroll' on graph in javafx application (when mouse hovered on top of webview). able on web-browser using following d3 js code

var svg = d3.select("body").append("svg")      .attr("width", width)      .attr("height", height)      .call(d3.behavior.zoom().on("zoom", zoomhandler))      .append('g');      function zoomhandler() {    svg.attr("transform",        "translate(" + d3.event.translate + ")"        + " scale(" + d3.event.scale + ")");  }

but if similar inside javafx application's webview, graph rendered in webview on scroll, disappears , reappears if bring mouse scroll initial position (when application started)

the following code how use webview render graph

        final url urlloadmaingraph = getclass().getresource("html/maingraph.html");                          wemaingraph.load(urlloadmaingraph.toexternalform());

is there wrong on being done ?

thanks

i cannot provide solution, have same problem. problem is, have not specified scale.

javafx jumping minimum maximum scale of zoom 1 "tip" on mousewheel :(. if specify in range, work out you. use example zoom little bit outside.

 var svg = d3.select("body").append("svg")     .attr("width", width)     .attr("height", height).call(d3.behavior.zoom().scaleextent([0.75, 1]);

best far... hoping anwsers!

(ps: couldnt comment... thats why kind of answer.
