javascript - How can I add space in the label of a graph made with dimple.js? -


i doing barplot dimple.js. code following:

 var data = [{x:1, y:10}, {x:2, y:15}, {x:3,y:27}]  var svg;   var chart;  var svg = dimple.newsvg("body", 800, 600);   var chart = new dimple.chart(svg, data);   chart.defaultcolors = [  new dimple.color("#ff0000", "blue"), // set red fill blue stroke  new dimple.color("#00ff00"), // set green fill darker green stroke  new dimple.color("rgb(0, 0, 255)") // set blue fill darker blue stroke  ];    x = chart.addcategoryaxis("x", "x");  chart.addmeasureaxis("y", "y");  chart.addseries("country", dimple.plot.bar);  x.addorderrule("x");  chart.draw();

it works fine when have 3 (or few) data points, when have more 2 hundred data points, x axis becomes cluttered units. there way show units in x label every n points? (so instead of showing 1,2,3... shows 1, n+1, 2*n+1,...) ?

you can modify after draw d3. here method remove labels leaving every nth one:

// pass in axis object , interval. var cleanaxis = function (axis, oneinevery) {     // should have been called after draw, otherwise nothing     if (axis.shapes.length > 0) {         // leave first label         var del = false;         // if there interval set         if (oneinevery > 1) {             // operate on axis text             axis.shapes.selectall("text").each(function (d) {                 // remove nth label                 if (del % oneinevery !== 0) {                     this.remove();                     // find corresponding tick line , remove                     axis.shapes.selectall("line").each(function (d2) {                         if (d === d2) {                             this.remove();                         }                     });                 }             del += 1;             });         }     } };

here's fiddle working case yours:
