Pie

I am dealing with a chart that has unwanted spacing on left and right side. I've been trying to remove it with no luck, and I don't know what else to do now. I've read the documentation thoroughly, but can't seem to find a solution. Is this possible to do? Let me know if more info is necessary, and I'll supply it.

Edit:

<div>

<canvas id=chart-gender></canvas>  

</div>





<script>

var gender_data = [10, 35];



var graph_gender_preset = {

    labels: [Female, Male],

    datasets: [

        {

            data: gender_data,

            backgroundColor: [#0fa0e3, #ff3549]

        }

    ]

};



var ctx3 = $(#chart-gender);



var chart_gender = new Chart(ctx3, {

type: 'doughnut',

data: graph_gender_preset,

options: {

        responsive: true,

        title: {

            display: false,

            position: top,

            fontStyle: bold,

            fontSize: 0,

            fullWidth: false,

            padding: 0

        },

        legend: {

            display: false,

            position: top,

            fullWidth: false,

            labels: { display: false, usePointStyle: true, fontSize: 15, fontStyle: bold }



        }

    }

});

</script>

The problem is not the doughnut, it is the canvas in which it is used.

The doughnut has to use a quadratic box, otherwise it would look like an ellipsis. So if you change the size of the canvas and make it quadratic you won't have any borders anymore.

Here is an JS Fiddle example.

<table border=1>

  <tr>

    <td>

      First

    </td>

    <td>

      <canvas width=100% height=100% id=myChart></canvas>

    </td>

    <td>

      Third

    </td>

  </tr>
