javascript - Make the X-Axis labels in chart.js increment by a certain scale

Question

I have labels ranging from 50-90, and every number in between in displayed.

I would like to list the labels by 5 or 10 because currently they are all crunched together.

It also make the left part of the y-axis cut off.

Answer 1

EDIT 2: Ok so i actually needed functionality like this in a project I am working on so i have made a custom build of chart.js to include this functionality.http://jsfiddle.net/leighking2/mea767ss/ or https://github.com/leighquince/Chart.js

It's a combination of the two solutions below but tied into the core of CHart.js so no need to specify custom scale and charts.

Both line and bar charts have a new option called

labelsFilter:function(label, index){return false;)

by default this will just return false so all labels on the x-axis will display but if a filter is passed as an option then it will filter the labels

so here is an example with both bar and line

var ctx = document.getElementById("chart").getContext("2d");
var data = {
    labels: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30],
    datasets: [{
        label: "My First dataset",
        fillColor: "rgba(220,220,220,0.5)",
        strokeColor: "rgba(220,220,220,0.8)",
        highlightFill: "rgba(220,220,220,0.75)",
        highlightStroke: "rgba(220,220,220,1)",

        data: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30]
    }]
};


var myLineChart = new Chart(ctx).Line(data, {
    labelsFilter: function (value, index) {
        return (index + 1) % 5 !== 0;
    }
});
