I am getting the required gradient in jsfiddle(through the above code) but the same thing isn't displayed in any web browser.I am using highcharts v 3.0.7.I can apply the background gradient but the individual graph gradient is not being applied in the web browsers. Thank You.

Share Improve this question asked Nov 12, 2013 at 5:45 deepjyoti22deepjyoti22 1973 silver badges11 bronze badges 3- 1 jsfiddle/BjL6r It looks beautiful. I think the issue you may have is the jQuery library. Maybe the order of loading the scripts is not correct... – MarsOne Commented Nov 12, 2013 at 5:49
- could you be more specific. gradient is working in the background of the graph but not within the graph itself. so maybe , its not the jQuery version. any other suggestions are welle. – deepjyoti22 Commented Nov 12, 2013 at 6:21
- @deepjyoti22 could you be more specific what is wrong with MarsOne example? For me it displays properly gradient for area charts. – Paweł Fus Commented Nov 18, 2013 at 16:01

Reset to default 3It looks like you aren't setting the linearGradient for the chart background correctly. Try something like:
chart : {
renderTo : 'container',
type : 'line',
backgroundColor : {
linearGradient : [0,0, 0, 300],
stops : [
[0, 'rgb(256, 256, 256)'],
[1, 'rgb(0, 0, 0)']
]
}
},
Linear gradients are documented here: http://www.highcharts./docs/chart-design-and-style/colors
Note the last number (300 vs your value of 0) in the linearGradient option. http://jsfiddle/K4cpG/
