我想为此图表添加趋势线，我在google中搜索并从此链接获取代码：把所有这些一起。
This is the high chart graph code.

I want to add trend line for this chart, i searched in google and got the code from this link : https://github.com/virtualstaticvoid/highcharts_trendline and i added the trend line code like this .

and the trend line that acts according to the x-axis and y-axis values but on the x-axis values are date wise and the y-axis values are numbers ,please find the screen shot for the first code :
And this the trend line snapshot. please find.
please share any one of the code that i would like to add the two graphs in the same page , i have tried but the x-axis and y-axis values are different for the two graphs.
Thanks.
Numerous problems.
1.) You didn't really integrate the regresssion code into your plot, you just cut/pasted from the example and are over-drawing your plot. You need to add the regression line as a second series to your plot:
series: [{
name: 'RNA - CP ( Radio Network Availability - Customer Perceived)',
data: sourceData
},{
type: 'line',
marker: { enabled: false },
/* function returns data for trend-line */
data: (function() {
return fitData(sourceData).data;
})()
}]
2.) This is not valid javascript:
var sourceData = [
[18-Jul-14, 99.75], [19-Jul-14, 99.77],
[20-Jul-14, 99.78], [21-Jul-14, 99.84],
[22-Jul-14, 99.82], [23-Jul-14, 99.82],
[24-Jul-14, 99.76], [25-Jul-14, 99.78],
[26-Jul-14, 99.8], [27-Jul-14, 99.65],
[28-Jul-14, 99.94], [29-Jul-14, 99.8]
];
Those are strings and they aren't quoted. Regardless, strings won't cut it for the regression, it needs numbers. Since your dates are really categories, just use:
var sourceData = [
[0, 99.75], [1, 99.77],
[2, 99.78], [3, 99.84],
[4, 99.82], [5, 99.82],
[6, 99.76], [7, 99.78],
[8, 99.8], [9, 99.65],
[10, 99.94], [11, 99.8]
];
3.) Your series name is way too long for a right side legend (it squished the plot). In my example I moved it to the bottom.
Here's a example putting all this together.
