I have a weird question:
The series1 variable is an array of date-times, which are too long. Because of this, the chart cannot display correctly. However, if I change series1 to make it contain the values of series2. It will work correctly. Can you let me know what I should do?
Also, how can I get each value in series1 shown as a date? suppose it is a variable from flask {{series1}}. thank you.
$(function () {
var series1 = [1489298400000L, 1492923600000L, 1492318800000L, 1480226400000L, 1494133200000L, 1490504400000L, 1488088800000L, 1475384400000L, 1493528400000L, 1491109200000L, 1480831200000L, 1471755600000L]
var series2 = [1, 7, 2, 1, 4, 1, 1, 1, 4, 6, 1, 1]
var series3 = [102, 95, 110, 111, 81, 104, 99, 92, 90, 100, 103, 98]

About suffix "L" on the end you can read here.
What you need at first to make all items in series1 array be a string, because as it now, you will have an error. Then remove "L" and convert to dates
let series = ['1489298400000L', '1492923600000L', '1492318800000L', '1480226400000L', '1494133200000L', '1490504400000L', '1488088800000L', '1475384400000L', '1493528400000L', '1491109200000L', '1480831200000L', '1471755600000L'];
let series1 = series.map((item) => {
let date = new Date(parseInt(item.replace("L", ""))));
return `${date.getMonth()} ${date.getFullYear()}`;
});
I am using dual-axis highcharts. In the y-axis the values are too big to read. I wold like to convert them to shortcuts like 1K for 1000 and 1.0L for 100000 and 1.0M for 1000000 and 35.8M for 35869982 and 3.5M for 3550977.

Here I have rounded up where I want to make changes in the below figure
You need to make a use of formatter:
formatter: function(){
return this.value/1000000 + "M";
}
Fiddle
To utilize the built in "shortening" functionality you can just remove your yAxis.label.format. You have currently set it to {value}, which is the default, but manually setting it seems to prevent the metric prefixes from being applied.
Look at this JSFiddle example, where all I've changed is removing the following line from both of your y-axis labels:
format: '{value}'
With this automatic shortening the following metric prefixes may be applied:
[ "k" , "M" , "G" , "T" , "P" , "E"]
You can set your own values with the lang.numericSymbols option (API).
I have this annoying thing in Highcharts that I cannot figure out. I have graphs that are dynamically generated and can contain multiple columns and splines. In the example the spline is a temperature measurement and contains lots of data points. The two columns are grouped by day and therefore contain only one value per day.
When I use this combination the column width becomes almost invisible:

I have been searching for ways to dynamically control the width of columns by using pointWidth but this gets me into a hole new area of issues, as I am not always sure if there is a combination of columns and splines and what the date range is.
Is there a trick to solve this? I hope I have missed something simple.
I was reading through the API description of Highcharts when I noticed an option to have multiple x axis. Since my problem seemed to be related to scaling on the x axis I decided to give it a go...
I created a new x axis for the line data and it works like a charm. Of course we do not want to see multiple x axis, so a little fiddling with the settings hides it again.
My x axis definition now looks like this:
xAxis: [{
type: 'datetime',
},{
type: 'datetime',
lineWidth: 0,
minorGridLineWidth: 0,
lineColor: 'transparent',
opposite: true,
labels: {
enabled: false
},
minorTickLength: 0,
tickLength: 0
}],
On the data series that has 'too many' points I simply added 'xAxis: 1'.
