A smoother line is needed (the line should rise smoothly and evenly), but the values should not change. Is it possible to build a more straight line without changing the values?

<script>

}
}
}

data: gdata,
lineWidth: 3,

}],
}
}]
}
});
}
</script>
Is it possible to do it? And how to modify my code for it?
Thank you very much in advance!
As I mentioned in the comment current line shape is at it is because of the points positions on the chart. If you don't need to keep points actual positions the solution which you can use is to use the dummy data for the points and use the correct one in the dataLabels. See:
Demo: https://jsfiddle.net/BlackLabel/fshx3n50/
data: [{
y: 5,
z: 0.20
}, {
y: 10,
z: 1.40
}, {
y: 18,
z: 6.20
}, {
y: 30,
z: 18.00
}, {
y: 50,
z: 73.00
}],
I also changed the formatter function to display the z value in dataLabel:
formatter: function() {
return '<div class="chitem-time">' + this.x + '</div>' +
'<div class="chitem-val">' + Highcharts.numberFormat(this.point.z) + '<sup>REM</sup></div>';
}
I'm making a chart which has two x-axis and two y-axis on it.
It's a line chart with smooth curve. It should have lines from two series as dash or longdash but when I use dashStyle it throws error.
I have seen many examples where it's working in jsFidler or Plunker.
Below is my code. I'm using Angular 4 with typescript.enter image description here
var ctx = document.getElementById("PumpCurveEvolutionChart") as HTMLElement;
var chart = Highcharts.chart(ctx, {
chart:{
height: 350,
width: 700,
marginTop: 30,
},
title: { text: 'Flow (l/S)', verticalAlign: 'bottom'}
,
xAxis: [{
categories: this.getPumpCurveEvolution.OEMFlow,
},
{
categories: this.getPumpCurveEvolution.CurrentFlow,
opposite: true,
labels: { enabled: false },
minorTickLength: 0,
tickLength: 0
}],
yAxis:[{
min: 0,
max: 100,
labels: { enabled: true},
title: { text: 'Head (m)'},
},{
min: 0,
max: 110,
opposite: true,
labels: { enabled: true},
title: { text: 'Efficiency (%)'}
}],
plotOptions: {
series: {marker: { enabled: false}, lineWidth: 2},
//line: { dashStyle: 'dash'}
},
legend: {enabled: false,
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -30,
y: 100,
borderWidth: 0
},
series: [{
xAxis:0,
yAxis:0,
data: this.getPumpCurveEvolution.OEMHead,
},
{
xAxis:0,
yAxis:1,
data: this.getPumpCurveEvolution.OEMHydrEfficiency,
},
{
xAxis:1,
yAxis:0,
data: this.getPumpCurveEvolution.CurrentHead,
},
{
xAxis:1,
yAxis:1,
data: this.getPumpCurveEvolution.CurrentHydrHead,
}]
});
You can use dashStyle by extending HighCharts.IndividualSeriesOptions:
export interface IHighChartCustomSeries extends Highcharts.IndividualSeriesOptions {
dashStyle?: string
}
I have a problem with a highcharts graph, regarding overlapping of multiple axes.
There are 2 types of series, one type column and one type line. I want the line type to be always above the others and never intersect them.
You may see my problem here:

Anticipated thank you for any help provided.

},
{

type: 'column',
color: '#00FF00',
yAxis: 0,
data: [16, 16, 106, 12, 11]
},
{
name: 'L3',
yAxis: 1,
data: [38, 24, 37, 29, 37]
}
]
});
You can try to set correct min/max values in both yAxis like here http://jsfiddle.net/99tC7/1/
I've created a line and a bar graph that share the xAxis. But for some reason it chooses to display the value instead of date, even though I am supplying it the standard way.
What am I missing here?

If you added the the "type" to the xAxis definition then the x values will be interpreted as dates and times rather than decimal values
xAxis: {
type : "datetime", //add this line
gridLineWidth: 1,
labels: {
rotation: -45,
align: 'right',
style: {
fontSize: '13px',
fontFamily: 'Verdana, sans-serif'
}
}
},
you may have to fiddle with the start times and intervals to get HighChart to correctly interpret your x-values.
see this demo on the highchart website as an example. http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/line-time-series/
The reason is that you are not actually creating a Stock chart. Your code looks like:
var chart = new Highcharts.Chart(options);
If you want it to be a Stock chart do:
var chart = new Highcharts.StockChart(options);
A Chart by default is a category chart. StockChart is time-based.
You can use dateFormat to replace time in miliseconds with date.
http://jsfiddle.net/3bE4X/
formatter:function(){
return Highcharts.dateFormat('%d / %m / %Y',this.value);
}

EDIT: A more elegant solution that doesn't require you to edit highcharts.js but instead makes use of prototype to extend Highcharts. Add the following Javascript snippet to your code before you instantiate any graphs:
Highcharts.Series.prototype.drawGraph = (function (func) {
return function () {
func.apply(this, arguments);
if (typeof this.options.areaPadding !== "undefined"){
for (i=2;i<this.areaPath.length;i+=3){
this.areaPath[i]+=this.options.areaPadding;
}
}
};
} (Highcharts.Series.prototype.drawGraph));
Then use the areaPadding parameter like so to add space between the line and the area:
var chart = new Highcharts.Chart({
plotOptions:{
area: {
areaPadding: 4
}
}
});
