I am working with Highcharts Bar Graph (vertical) and I would like to have the Members data to appear on top of each bar (hovers we will keep as well which is working). I've tried various ways with plotOptions and could not get this to work to show Members data on top of the bar graph view. The first link is my working code.
**https://codepen.io/jenfloods/pen/jOyXEQd**
The second link above is the example is how I would like the data text to appear on top of a bar graph with white shadow letters but this would apply to my vertical bars and not horizontal as this example shows.

Anyone has an example or can work with my code to make it happen?
You need to enable data labels for series and use the configuration like below:
plotOptions: {
series: {
...,
dataLabels: {
rotation: 90,
verticalAlign: 'top',
y: 10,
align: 'left',
inside: true,
enabled: true,
color: '#FFFFFF'
},
}
}

When I try to hover mouse along y-axis I observed that the tooltip is at the top but the point selected is at the bottom of the graph. This is because the point below might be the second point when we hover along the x-axis.
How do I make highcharts transverse points along the y-axis ?
Note: It is not a shared tooltip
I have tried setting the following attributes in the tooltip:
followPointer: true,
followTouchMove: true,
That is because of the default value of the findNearestPointBy option, which is 'x'. You can set it to 'y' or 'xy':
series: [{
findNearestPointBy: 'xy',
...
}]

I'm trying to show the values of my series data in the highchart legend using this and I've tried pretty much all the examples I can find online, specifically adding:
legend: {
enabled: true,
floating: true,
align: 'left',
verticalAlign: 'top',
y: 35,
labelFormat: '<span style="color:{color}">{name}</span>: <b>{point.y:.2f} USD</b> ({point.change:.2f}%)<br/>',
borderWidth: 0
},
But nothing is working in order to show the values of the data in my highchart and to display the highchart vertically to the right. Can someone please tell me what I'm doing wrong please?

Legend options do not apply because you placed them in series object. I corrected the demo and add couple of additional options, like layout.

I am using ChartJS alongside the ChartJs annotation plugin. The plugin allows users to draw lines on a chart.
I am trying to draw a horizontal line on my line chart that ends at a specific value instead of extending all of the way to the end of the chart.
Here is what the chart is supposed to look like, it is the red line labeled 'Peak':
The line should end at the largest value in the data array. However right now, the horizontal line extends all of the way to the end of the chart as you can see in the fiddle below.
Here is the code for the annotation:
annotation: {
drawTime: 'afterDatasetsDraw',
events: ['click'],
dblClickSpeed: 350,
annotations: [{
drawTime: 'afterDraw', // overrides annotation.drawTime if set
id: 'a-line-1', // optional
type: 'line',
mode: 'horizontal',
scaleID: 'y-axis-0',
value: '1300',
borderColor: 'red',
borderWidth: 2,
// Fires when the user clicks this annotation on the chart
// (be sure to enable the event in the events array below).
onClick: function(e) {
// `this` is bound to the annotation element
}
}]
Is it possible to limit the width of the line like this?
Here is the fiddle

I really want to know how to make datalabels always in center of each slice in pie chart.
The normal state look like this(you can also see this example here)
$('#container').highcharts({
chart: {
type: 'pie'
},
plotOptions: {
pie: {
center: ["50%", "50%"],
dataLabels: {
distance: -50
}
},
series:{
events:{
load:function(){
console.log(this.chartWidth, this.chartHeight);
}
}
}
},
series: [{
data: [
['Firefox', 44.2],
['IE7', 26.6],
['IE6', 20],
['Chrome', 3.1],
['Other', 5.4]
]
}]
});
But, when I decrease the width or height of this chart, datalabels combined, which look like the image below. I think it is the problem of distance property. I've tried to change distance dynamically but failed.
As a result, what I want to do is to locate datalabels always in center of the each slice even decreasing/increasing chart size.
This is a tough one. From my experiences, there's not (currently) a way to explicitly center the labels directly in the middle of each pie slice. I've tried positioning the labels as you did in your example with the same (unsatisfactory) results, especially in smaller browser windows.
I'd recommend either using a legend to show the categories/types in your pie or consider using a stacked bar chart instead (see http://www.highcharts.com/demo/bar-stacked).
I hope this is helpful!
I'm new with Google Charts and I am not able to obtain a fine result with the texts surrounding the graph.
This is how my chart looks:
As you can see, it does cut both Horizontal-Axis and Legends, so the final result is not as good as It could be. Is there a way to solve this? I've been reading the official documentation and some posts from here, but I haven't found the way to do this.
Recap: How do we modify the legend or the axis texts so they are fully visible?
After some time experimenting, I daresay it is not posible to choose how much part of the words on legend or axis you can show.
However, you can play with their sizes and position so you get -more or less- what we were looking for.
This is what can be done:
legend: {position: 'top', textStyle: {fontSize: 14}}
I've also made the image a little bit bigger so it fits the x-axis without problems (There was also the option of making its text smaller).
So doing this, this is what you get:
Its basically about setting your chart area vs width / height.
width: [yourChoice]px,
chartArea: {width: '50%'}
ref https://stackoverflow.com/a/6870732/661584
Also as #ArcDare says using the other available styling options such as font size etc
For optmized chart area,
chartArea: {'width': '90%', 'height': '60%'},
legend: { position: 'bottom' },
hAxis : { textStyle : { fontSize: 10} },
vAxis : { textStyle : { fontSize: 10} },
The trick is setting axis textStyle fontsize will enable better placement of legend on the bottom of the chart as the chart Area is about 60-70%
Feel free to use my custom Google Charts plugin which creates both chart and table.
