Is there any way to completely hide scrollbar's buttons which contain arrow?
In addition to this, is there any way I can set the position of scrollbar such as setting y value so that the scrollbar hovers on the chart?
Setting its color to transparent doesn't help.
scrollbar: {
buttonBackgroundColor: 'transparent',
buttonBorderWidth: 0,
buttonArrowColor: 'transparent',
buttonBorderRadius: 0
}
EDIT:
Even if I hide the elements, I cannot use the space left as the picture below.
You can manipulate SVG elements.
chart: {
events: {
load: function () {
var chart = this;
chart.scroller.scrollbarButtons[0].hide();
chart.scroller.scrollbarButtons[1].hide();
}
}
},

As I am forcing Highcharts to show the last label on the xaxis, this last label is partially hidden, or partly disappears:
Why is that? And what can I do? Setting the »marginRight« in the »chart« settings does not do the trick.
Thanks for any hints.
You can set align: 'right' attribute for the last label:
chart: {
events: {
render: function() {
var ticks = this.xAxis[0].ticks;
Highcharts.objectEach(ticks, function(tick) {
if (tick.isLast && tick.label.xy.opacity) {
tick.label.attr({
align: 'right'
});
}
});
}
}
}

This might be the chart container width being too small, or the chart itself is too small.
You should try:

I need the dataLabels to be always displayed at the right end of bar chart irrespective of the data value. According to the Highcharts API, the dataLabel position is adjustable only relative of its current position. Is there a way to change the datalabel position relative to the chart area?
You're looking for something like this?
If you make the labels HTML elements instead of SVG elements..
plotOptions: {
bar: {
dataLabels: {
enabled: true,
allowOverlap: true,
//Labels are easier to move around if we switch from SVG to HTML:
useHTML: true,
}
}
}
..it's quite easy to move them around using CSS:
.highcharts-data-labels.highcharts-bar-series {
/* Stretch the labels container across the whole chart area: */
right: 0;
}
.highcharts-label.highcharts-data-label,
.highcharts-label.highcharts-data-label span {
/* Disable the default label placement.. */
left: auto !important;
/* ..and put them along the right side of the container */
right: 8px;
}

You can also position data labels in the render event:
events: {
render: function() {
var chart = this;
chart.series.forEach(function(s) {
s.points.forEach(function(p) {
if (p.dataLabel) {
p.dataLabel.attr({
x: chart.plotWidth - p.dataLabel.width
});
}
});
});
}
}

I'm displaying the x-axis of my Highstock chart at the top of the chart area with xAxis: { opposite: true}.
However the tooltip continues to show the x-axis value at the bottom of the chart, see for example here http://jsfiddle.net/ckj7kf2y/
Is there any way I can change the positioning of this be at the top, close to the x-axis?
Bonus points if someone knows why the tooltip.positioner callback isn't called when tooltip: { split: true }
It's possible to wrap core code to add this feature like in this demo: http://jsfiddle.net/ygmbwxtx/
(function(H){
H.wrap(H.Tooltip.prototype, 'renderSplit', function (proceed) {
proceed.apply(this, [].slice.call(arguments, 1));
var tooltip = this,
topAxis = tooltip.options.topAxis,
axisTT = tooltip.tt,
top = tooltip.chart.plotTop;
if (topAxis) {
axisTT.attr({
y: top - axisTT.height,
anchorY: top + 10
});
}
});
}(Highcharts))
and in chart's options:
...
tooltip: {
split: true,
topAxis: true
...
Bonus: positioner is not used for split tooltip - split uses own logic for positioning
If I try to rotate the data labels in my column charts, I can not align the labels at the bottom of my columns, verticalAlign appears to be completed ignored.
basically trying to use:
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
verticalAlign: 'bottom',
rotation: -90
}
}
}
fiddle with it at: http://jsfiddle.net/FbhAs/
Anyone know a work-around?

The dataLabels don't seem to align correctly to the bottom. Instead, use the axis labels themselves. For a column chart, you would put this in xAxis for the chart options.
xAxis: {
labels: {
enabled: true,
rotation: -90,
y: -10 // negative goes upwards
}
}
You can then add styling, a formatter function, etc. as per dataLabels.
You can update datalabels position, based on translate() function which allows to "move" svg object for defined postiison.
http://jsfiddle.net/wMLg6/37/
var bottom = chart.plotHeight - 20;
$.each(chart.series[0].data,function(i,data){
data.dataLabel.attr({
y: bottom
});
});
I have a (horizontal) bar chart and I want to add dataLabel's at the base (or left most part) of the bar for the series.
similar to this: http://flowingdata.com/2009/05/22/poll-results-what-data-related-area-are-you-most-interested-in/
Is there a way using the formatter function to set this value?
plotOptions: {
bar: {
dataLabels: {
formatter: function() {
this.series.options.dataLabels.x = ?????????????
return this.y;
},
The task of the formatter function is to format the label text. It gives you a way to modify the internal state of the chart, but that's really just a hack and as such may or may not work.
One way to place the labels at the base is to use stack-labels instead of data-labels (the data-labels will be placed at the top of the bar either aligned left or right). To configure stack labels at the base, do:
yAxis: { // The y axis is horizontal 'bar' layout
stackLabels: {
style: {
color: 'white' // Make the labels white
},
enabled: true, // Enable stack labels
verticalAlign: 'middle', // Position them vertically in the middle
align: 'left' // Align them to the left edge of the bar
}
}
You will also need to set stacking to 'normal':
Example on jsfiddle:
Update: Labels for stack-totals will show the sum of all series for a specific category (stack) so only in the case of having one single series in the chart will stack-labels and data-labels show the same value.
