i am trying to use gradient for my charts with angularjs1 using angular-chart.js version 1.0.0 but it seems that fillcolor does not recognize gradient here is my code down below
var app = angular.module('starter', ['ionic', 'ngCordova', 'chart.js', 'ionic-modal-select']).controller('graphCtrl', function($scope) {
var ctx = document.getElementById('base2').getContext('2d');
var gradient =ctx.createLinearGradient(0, 0, 0, 400);
gradient.addColorStop(0, 'rgba(243, 103, 101,0.5)');
gradient.addColorStop(1, 'rgba(0, 89, 179,0.5)');
$scope.labels2 = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'];
$scope.data2 = [
[65, -59, 80, 81, -56, 55, -40],
[28, 48, -40, 19, 86, 27, 90]
];
$scope.type2 = 'bar';
$scope.colors2 = [{
fillColor: gradient,
strokeColor: 'rgba(151,187,205,1)',
pointColor: 'rgba(151,187,205,1)',
pointStrokeColor: '#fff',
pointHighlightFill: '#fff',
pointHighlightStroke: 'rgba(151,187,205,0.8)'
}, {
pointDot: false,
pointDotRadius: 0,
fillColor: gradient,
strokeColor: 'rgba(187,155,206,1)',
pointColor: '#BB9BCE',
pointStrokeColor: 'rgba(187,155,206,1)',
pointHighlightFill: '#fff',
pointHighlightStroke: 'rgba(187,155,206,1)'
}];
$scope.datasetOverride2 = [{
label: "Bar chart",
borderWidbelowbelowth: 1,
type: 'bar'
}, {
label: "Line chart",
borderWidth: 3,
hoverBackgroundColor: "rgba(255,99,132,0.4)",
hoverBorderColor: "rgba(255,99,132,1)",
type: 'line'
}];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div class="chart-container" >
<canvas id="base2" class="chart-base" chart-type="type2" chart- data="data2" chart-labels="labels2" chart-colours="colors2" chart- options="options2" chart-dataset-override="datasetOverride2" >
</canvas>
</div>
How can declare gradient so it works ? i have tried this
var ctx = angular.element(document).find("canvas")[0].getContext("2d");
var gradient = ctx.createLinearGradient(0, 0, 0, 400);
gradient.addColorStop(0, 'rgba(243, 103, 101,0.5)');
gradient.addColorStop(1, 'rgba(0, 89, 179,0.5)');
but it doesn't work either.
