d3.js - 'd3-circle-text' on zoomable circle-pack -

-

the 'd3-circle-text' plug-in works great on static circle-pack (many musically-ut contributing https://github.com/musically-ut/d3-circle-text). however, on zoomable circle-pack, labels fly place (in fiddle, stay static not repositioning on zoom).

is possible circle-text zoom circles? (if plug-in isn't zoomable, that's ok. i'll try labelling approach.)

here's code section i'm working on:

////////////circle text         var circletext = d3.circletext()             .radius(function(d) {                 return d.r - 5;             })             .value(function(d) {                 return d.key; //get lables             })             .method('align')             .spacing('exact')             .precision(0.1)             .fontsize('100%');          var gtexts = svg.selectall('g.label')             .data(pack.nodes) //returns names              .enter()             .append('g')             .classed('label', true)             .attr('transform', function(d) {                 return 'translate(' + d.x + ',' + d.y + ')';             });          /*.attr("x", function (d) { return d.x; })             .attr("y", function (d) { return d.y; }); */ attempt - not working           /*.attr("cx", function (d) { return d.x; })            .attr("cy", function (d) { return d.y; }); */ attempt - not working      //only put on 'parent' circles              gtexts.filter(function(d) {                  return !!d.children;             })             .call(circletext)             //.style('fill', 'white');

here's full fiddle: http://jsfiddle.net/cajmcmahon/9a5xaovv/1/

thanks help.

i have updated plugin @ musically-ut/d3-circle-text

the layout generation has been simplified , handles transitions correctly.

the updated fiddle: http://jsfiddle.net/nxmkoo95/

notable changes

  • hoisted definition of circletext top level , removed call .precision.
  • used class .leaf-label identify text labels had manually moved.
  • added call update radius function of circletext , moved g.label correct place.
function zoom(d, i) {     var k = r / d.r / 2;     x.domain([d.x - d.r, d.x + d.r]);     y.domain([d.y - d.r, d.y + d.r]);      var t = svg.transition()         .duration(d3.event.altkey ? 7500 : 750);      t.selectall("circle")         .attr("cx", function(d) {             return x(d.x);         })         .attr("cy", function(d) {             return y(d.y);         })         .attr("r", function(d) {             return k * d.r;         });      circletext.radius(function (d) { return k * d.r - 5.0; });     t.selectall('g.label')         .attr('transform', function (d) {              return "translate(" + x(d.x) + ',' + y(d.y) + ')';         })         .filter(function (d) { return !!d.children; })         .call(circletext);      t.selectall(".leaf-label")         .attr("x", function(d) {             return x(d.x);         })         .attr("y", function(d) {             return y(d.y);         })         .style("opacity", function(d) { return k * d.r > 20 ? 1 : 0; });      node = d;     d3.event.stoppropagation(); }

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
