Uncaught SyntaxError: Unexpected token ) when plotting a js chart - javascript

Uncaught SyntaxError: Unexpected token )
I get the above mentioned error in the following file (script):
var Alpha_access = c3.generate({

})
d3.csv('../static/CSV/Chart_data/alpha_access.csv?rnd='+(new Date).getTime(),function(data){
var d1 = data[0];
var d2 = data[1];
var a = (d2["Regression"] - d1["Regression"])/(d2["Access grade"] - d1["Access grade"]);
var b = d2["Regression"] - (d2["Access grade"]*a);
b = (Math.round(b*1000)/1000);
a = (Math.round(a*1000)/1000);
document.getElementById("equation2").innerHTML = "Alpha = " + a + "·Acces grade PAU + " + b;
})
I have a file which does exactly the same with another parameter (instead of alpha) and works fine. I have compared and reviewed the script and it looks fine. Any ideas?

Plotline (vertical line) in highcharts scatter chart

https://jsfiddle.net/7zL0v5oq/
I would like to have a plotline at today's date. The list can get quite long and in that case it helps with having an oversight. I fear it doesn't work because it is a scatter chart but I don't know what the problem is. I've searched all over the place but everything leads to plotlines, which clearly doesn't work. I would also be thankful if anyone knew, whether there was an easy way to filter my data the way I have it (standard highcharts filtering is deactivated but doesn't really help because of the static y values, so I get a huge, white space in the middle unless I filter at the edges. Thank you in advance for your help.

You have a typo, use plotLines instead of plotlines:
xAxis: {
plotLines: [{

...
}

Hi, everyone!! I am working on the echarts library, the only thing i want to change data is the axisLabel from Xaxis part.
What i mean is, for example, "2019-11-5, 2019-11-6...."and so on. So, i hope someone can help me out, thank you so much!!!

What i mean is, for example, "2019-11-5, 2019-11-6...."and so on. So, i hope someone can help me out, thank you so much!!!
First, create an array of dates like
var dates = ['2019-11-5','2019-10-3','2019-2-2','2019-1-4','2019-12-5'];
then in xAxis -> axisLabel return date
axisLabel: {
formatter: function (val,index) {
return dates[index];
}
}

I just need to simplify sending data via d[0], d[1] etc. Is there any kind of loop or anything else I can use?
You could take a function which takes the data and a pattern for the wanted elements and an offset for increment for the next row.
function mapByPattern(data, pattern, offset) {
var result = [], i = 0;
while (i < data.length) {
result.push(pattern.map(j => data[i + j]));
i += offset;
}
return result;
}
var data = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11],
result = { series: [
{ name: 'Temperature', data: mapByPattern(data, [0, 1], 3) },
{ name: "Humidity", data: mapByPattern(data, [0, 2], 3) }
]};
console.log(result);

HighCharts inside of a javascript function

I'm trying to draw a 3d box after a user has selected some data from the server.
When I put the highcharts inside of a js function, it throws some errors.
My code is:
Chart It<br/>
<div id="container" style="height: 400px"></div>
<script>
var chart;
function chart3d() {
// Give the points a 3D feel by adding a radial gradient
Highcharts.getOptions().colors = $.map(Highcharts.getOptions().colors, function (color) {

var posX = eStart.pageX,
posY = eStart.pageY,
alpha = chart.options.chart.options3d.alpha,
beta = chart.options.chart.options3d.beta,
newAlpha,
newBeta,
sensitivity = 5; // lower is more sensitive
$(document).on({
'mousemove.hc touchdrag.hc': function (e) {
// Run beta
newBeta = beta + (posX - e.pageX) / sensitivity;
chart.options.chart.options3d.beta = newBeta;
// Run alpha
newAlpha = alpha + (e.pageY - posY) / sensitivity;
chart.options.chart.options3d.alpha = newAlpha;
chart.redraw(false);
},
'mouseup touchend': function () {
$(document).off('.hc');
}
});
});
}
</script>
This loads fine if I do not put it inside of the chart3d function. Is there a way to get this working. The error message I get is:

You don't have a div with the id=container at the time you are calling the method.

High Charts windrose from API data (JSON)

I'm quite new here (and to web development in general), so please forgive any misuses that I perpetuate... I'm trying to create a basic windrose plot with data returned (in JSON) from the MesoWest Mesonet API service. I'm using HighCharts (or attempting to), and cannot quite get it to work. Perhaps this is due to my methodology of obtaining the data from the API itself as I'm a complete amateur in this regard. The following is the Javascript code, followed by the HTML for the page. Could someone please take a look and let me know what I've done wrong? Nothing displays on the page when I attempt to load it. In addition, if you're curious as to the specifics of an API call for MesoWest, like the one I've employed here, please see http://mesowest.org/api/docs/

I appreciate any guidance in this regard, thanks!!!

#W.Howard, I think the problem here is how you are treating and preparing the JSON response from the API. Consider the following JavaScript to retrieve and parse out the data:
/*
* Helper function
* scalarMultiply(array, scalar)
*/
function scalarMultiply(arr, scalar) {
for (var i = 0; i < arr.length; i++) {
arr[i] = arr[i] * scalar;
}
return arr;
}
/*
* getQuery(station, api_token)
*/
function getQuery(station, mins, api_token) {
$.getJSON('http://api.mesowest.net/v2/stations/timeseries?callback=?', {
/* Specify the request parameters here */
stid: station,
recent: mins, /* How many mins you want */
obtimezone: "local",
vars: "wind_speed,wind_direction,wind_gust",
jsonformat: 2, /* for diagnostics */
token: api_token
},
function(data) {
try {
windSpeed = data.STATION[0].OBSERVATIONS.wind_speed_set_1;
windDir = data.STATION[0].OBSERVATIONS.wind_direction_set_1;
windGust = data.STATION[0].OBSERVATIONS.wind_gust_set_1;
} catch (err) {
console.log("Data is invalid. Check your API query");
console.log(this.url);
exit();
}
/* Convert from knots to mph */
windSpeed = scalarMultiply(windSpeed, 1.15078);
//windGust = scalarMultiply(windGust, 1.15078);
/* Create and populate array for plotting */
windData = [];
for (i = 0; i < windSpeed.length; i++) {
windData.push([windDir[i], windSpeed[i]]);
}
/* Debug */
// console.log(windData);
console.log(this.url);
plotWindRose(windData, mins);
})
};
What we had now is an 2D array with wind direction and wind speed that we can pass to the plotting function. Below is the updated plotting function:
/*
* Plot the wind rose
* plotWindRose([direction, speed])
*/
function plotWindRose(windData, mins) {
/*
* Note:
* Because of the nature of the data we will accept the HighCharts Error #15.
* --> Highcharts Error #15 (Highcharts expects data to be sorted).
* This only results in a performance issue.
*/
var categories = ["0", "45", "90", "135", "180", "225", "270", "315"];
$('#wind-rose').highcharts({
series: [{
name: "Wind Speed",
color: '#cc3000',
data: windData
}],
chart: {
type: 'column',

},

},
xAxis: {

type: "",
tickInterval: 45,
tickmarkPlacement: 'on',
labels: {
formatter: function() {
return categories[this.value / 45] + '\u00B0';
}
}
},
yAxis: {
min: 0,
endOnTick: false,
showLastLabel: true,
title: {
text: 'Frequency (%)'
},
labels: {
formatter: function() {
return this.value + '%';
}
},
reversedStacks: false
},
tooltip: {
valueSuffix: '%'
},
plotOptions: {
series: {
stacking: 'normal',
shadow: false,
groupPadding: 20,

}
}
});
