In my graphics i have many points and i set {marker: {enabled: false}} example
plotOptions: {
series: {
marker: {
enabled: false
}
}
},
example
But, if graph points has nulls, all graph hidden.
example
How to show alone points, with {marker: {enabled: false}} ?
In case when you have null values, it means that "lines" between doesn't exist, and only markers remain. So when you disable marks, series in not visible.

Using this example from Highcharts for displaying grouped column chart with negative values
https://www.highcharts.com/demo/column-negative
When we have less attributes in x-axis, the distance between both bars of the same value becomes wider. Can we reduce this distance by using any option & make the two bars look close to each other for each month. Attaching output with question.
Sample chart
Options I am using are:
plotOptions: {
column: {
dataLabels: {
enabled: false
},
pointWidth: 15
},
series: {
centerInCategory: true
}
},
Using the groupPadding and pointWidth property you can adjust the space between the grouped columns.
plotOptions: {
column: {
dataLabels: {
enabled: false
},
groupPadding:0.35,
pointWidth: 25
}
},
API:

To ease graph readability, I've turned markers off on my highstock spline chart (markers : enabled : false). I also wanted to broke the graph in case of irregular interval between data and so I have successfully set the gapSize to 1. However, this has the bad side of hidding single data that are not linked from one side or an other.
Here's an example (you'll easily see that some of the points are hidden) : http://jsfiddle.net/qosdc6hr
series: [{
marker:{
enabled:false
},
gapSize: 5,
[...]
}]
I want to have these single points drawn on the chart to make them visible at first glance. Is there a way to do it?
You can enable marker for a specific point like this:
data: [
{ x: Date.UTC(1970, 9, 27), y: 0, marker: { enabled: true }},

I'm trying to add SMA (Simple moving average) into my highstock with dataGrouping.
dataGrouping works fine without SMA. But when I add SMA it only group data on daily basis. Has anyone got the same problem?
I've checked the chart element and I can see the series & SMA object they all got the dataGrouping attribute but still not display properly in the chart.
I tried to add dataGrouping in both plotOptions.series & plotOptions.sma or add it in series respectively but none of them work.
let dataGrouping = {
forced: true,
units: [
['week', [1]],
]
};
const options = {
//...
plotOptions: {
candlestick: {
color: 'green',
upColor: '#e00000',
},
series: {
marker: {
enabled: false,
},
states: {
hover: {
enabled: true,
lineWidth: 1.5,
}
},
dataGrouping,
},
sma: {
dataGrouping,
}
},
}
My highcharts verion is 6.0.7
I also tried to add dataGrouping on an official example and here's the link: http://jsfiddle.net/tuuz4yho/8/
and here's another example with a simple line chart
https://jsfiddle.net/Lyf6vzev/19/
But dataGrouping still not work on SMA lines.
Anyone know how to group SMA weekly or monthly?
Really need your help!
Thanks! :)
Turns out it's a known bug:
https://github.com/highcharts/highcharts/issues/7823
The workaround is setting dataGrouping.approximation and dataGrouping.groupPixelWidth in the indicator config.
I use Highcharts to visualize 3D charts in my project. Particularly I am interested in showing a 3D scatter plot like this. Below the chart you can see the options as well as the respective jsFiddle.
Is there a possibility to display a label with every point's name always i.e. that hovering is not required?
Thanks!
Within the series you can enable the datalabels like this:
series: [{
dataLabels: {
enabled: true,
},
}]
http://jsfiddle.net/oghokm8w/1/
then you could use the formatter to customise the text to be displayed:
series: [{
dataLabels: {
enabled: true,
formatter: function () {
return this.point.x;
},
}
}]
I am having trouble getting the marker radius working with high stock charts. I have been trying to get this working using both plot options, and a setting against the series directly:
plotOptions: {
series: {
marker: {
radius: 90
}
}
},
(or see http://jsfiddle.net/zMH7Q/).
Changing other attributes such as the marker shape works fine, but any changes to the radius seem to be ignored. I have tried setting this in both plot options, and directly against the series but to no avail. It is definately mentioned in the documents (http://api.highcharts.com/highstock#plotOptions.area.marker.radius) so should work unless I am doing something stupid (fairly likely).
Any help would be appreciated :-)

In HighStock, unlike HighCharts, the default for marker is enabled: false, this is because the data tends to be very dense and markers wouldn't add much value to the data comprehension of the user.
You need to modify your code to:
plotOptions: {
series: {
marker: {
enabled: true,
radius: 90
}
}
},
for the markers to show up.
EDIT: I will leave the above up in case someone comes across this and needs it. What David really wants to know is whether the series symbol during hover can be changed. The code for that is:
plotOptions: {
series: {
marker: {
lineColor: null,
states: {
hover: {
fillColor: 'white',
radius: 10
}
}
}
}
}
Which is straight from the Highcharts API reference at http://api.highcharts.com/highcharts#plotOptions.scatter.marker.states.hover.radius
