I am developing my first sample code using angular chart.js,I am unable to change custom height and width, How can i change height and width of my canvas.
CODE:
CSS
#myChart{
width:500px;
height:500px;
}
HTML
<body ng-controller="LineCtrl">
<canvas id="myChart" ></canvas>
<div class="chart-container">
<linechart data="data" options="options" mode=""></linechart>
</div>
Javascript
var data = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [
{
label: "My First dataset",
fillColor: "rgba(220,220,220,0.2)",
strokeColor: "rgba(220,220,220,1)",
pointColor: "rgba(220,220,220,1)",
pointStrokeColor: "#fff",
pointHighlightFill: "#fff",
pointHighlightStroke: "rgba(220,220,220,1)",
data: [65, 59, 80, 81, 56, 55, 40]
},
{
label: "My Second dataset",
fillColor: "rgba(151,187,205,0.2)",
strokeColor: "rgba(151,187,205,1)",
pointColor: "rgba(151,187,205,1)",
pointStrokeColor: "#fff",
pointHighlightFill: "#fff",
pointHighlightStroke: "rgba(151,187,205,1)",
data: [28, 48, 40, 19, 86, 27, 90]
}
]
};
var options = {
scaleOverlay : false,
scaleOverride : false,
scaleSteps : null,
scaleStepWidth : null,
scaleStartValue : null,
scaleLineColor : "rgba(0,0,0,.1)",
scaleLineWidth : 1,
scaleShowLabels : true,
scaleLabel : "<%=value%>",
scaleFontFamily : "'proxima-nova'",
scaleFontSize : 10,
scaleFontStyle : "normal",
scaleFontColor : "#909090",
scaleShowGridLines : true,
scaleGridLineColor : "rgba(0,0,0,.05)",
scaleGridLineWidth : 1,
bezierCurve : true,
pointDot : true,
pointDotRadius : 3,
pointDotStrokeWidth : 1,
datasetStroke : true,
datasetStrokeWidth : 2,
datasetFill : true,
animation : true,
animationSteps : 60,
animationEasing : "easeOutQuart",
onAnimationComplete : null
}
var ctx=document.getElementById("myChart").getContext("2d");
var myLineChart = new Chart(ctx).Line(data, options);
//console.log(myLineChart)
468
I did it with changing some options attribute and set width and height in context:-
var options = {
responsive: false,
maintainAspectRatio: false
}
In Js
var ctx=document.getElementById("myChart").getContext("2d");
ctx.canvas.width = 100;
ctx.canvas.height = 100;
var myLineChart = new Chart(ctx).Line(data, options);
I did by adding via canvas style. Tested with Pie Chart. Example:
<canvas id="pie" class="chart chart-pie" style="height:40px;"
chart-data="pieChart.data" chart-labels="pieChart.labels"
chart-colours="pieChart.colours"
chart-options="pieChart.options">
</canvas>
Code:
$scope.pieChart = {};
$scope.pieChart.labels = ['Label 1', 'Label 2'];
$scope.pieChart.data = [10,20];
$scope.pieChart.colours = ['#1EF9A1', '#FD1F5E'];
// This option is important!!!
$scope.pieChart.options = {
responsive: false,
maintainAspectRatio: false
}
You can actually use the width and height attribute within the canvas tag. Example:
<canvas id="bar"
height="100"
width="100"
class="chart chart-bar"
chart-data="dataChart"
chart-labels="labels"
chart-click="onClick"
chart-options="options">
</canvas>
