I have a HighCharts Pie chart configured as a "donut" style, and I set the title "verticalAlign" to "middle" but this seems to center the title in the whole area taken up by the chart (including the legend) which is fine for a few data points, but once the chart has many points added, the title starts overlapping the colored segments and even the legend. Is there a way to center the title in just the donut?
Example:
Highcharts has quite a number of ways to adjust the style. Not clear how you display your title, but it seems that the problem is in the height of your legend. One way to go is to adjust the 'y' parameter of the title to move title a little:
title: {
text: 'A title to move',
align: 'center',
verticalAlign: 'middle',
y: -20,
}
Drawback is that it may not fill all the possible chart content, so you have to somehow estimate how much you want to adjust the 'y'.

After much trial and error, the final solution for my specific use-case involved:
Fixing the 'chart.spacingTop' parameter to 10 pixels. This fixed the top of the chart so it wouldn't dynamically change in the vertical space.
Setting 'plotOptions.pie.size' to '250px'. This fixed the pie size to 250px regardless of how many points were shown.
Setting 'plotOptions.pie.center' to '['50%', 105]'. This centered the chart at 50% width, 105px from the top.
Limiting my series to 24 data points max (to avoid a legend that was too long to manage)
Finally, I created a <div> right before the chart container that allowed me to use CSS to set it relative to the chart, positioning my label right in the center of the donut.
The result:

Is it possible in highcharts to make the chart width, the plotting area the same width whether there are labels or not?
For example, both these charts have width 150 but one looks thinner than the other because it has the labels enabled.
I can do this programmatically but it is a bit messy. Is there a way?. I tried, for example, to set the label as enabled but not visible but this combination of options does not exist.
Thanks for any help
You can set fixed chart margin:
chart: {
marginBottom: 20
}

Following this demo here (http://www.highcharts.com/docs/chart-and-series-types/combining-chart-types) I am trying to have a Pie chart and a bar chart on the same page.
The catch is I would like the Pie chart to be large on the left and then the bar chart on the right. I see the code to move the pie chart around, but I cannot figure out how to do the same with the bar chart, as it seems to want to span the entire container width. I understand that I could have two independent charts and place them in their own floating DIVs, but since the combining of charts is possible, I thought this would be a viable option.
You can set chart.marginLeft to half of the chart width. And set pie.center x coordinate to a negative value.
chart: {
marginLeft: 400
},
series: [{
center: ['-75%', '50%'],

I am using Highcharts area graph.
The type of the chart is "datetime".
The X-Axis labels get well adjusted as long as
Either the width of the chart container div is less than 900px
Or the width is not specified for the div
When I set the width of the container of the div more than 900px, either the labels are appended with the dots or get overlapped.
How it can be resolved. Thanks in advance for any suggestion or help.
You can add the tickInterval option to the x-Axis. This option determines the distance between the individual ticks. For example setting it to
tickInterval: 24*3600*1000
which resembles on day in milliseconds yields no overlapping labels for your chart:

You can also use a new option provided below by highcharts if you are comfortable with showing the labels in 2 or more lines and if you do not want rotated labels.
staggerLines: 2

I am using a pie chart for my diagram. The problems is sometimes the text or the name of a category is really long and it makes my pie chart gets smaller than usual.
How I can set a width limitation for each text?
This is my pie chart with a long category name:

Answered here, and here is a fiddle that demonstrates.
In brief - you can add a style to the dataLabels:
style: {
width: '50px'
}
I've just started using JqPlot and want to display a small chart
However there is always a small margin at the top and to the left.
Looking at the css produced the jqplot-event-canvas is given absolute position with top and left set at 10px.
Is there a simple way to solve this so that the pie is positioned without the extra spacing?
I've tried to set the padding to 0 in the grid and pie rendererOptions.
Also set show:false on the axes, title, ledgend ...,
Any ideas?
Try setting the gridPadding like this:
var plot1 = $.jqplot('pie1', [data], {
gridPadding: {top:0, bottom:0, left:0, right:0},
....
Because by default, each plot has the following grid padding:
{top:10, right:10, bottom:23, left:10};
I think this might explain the issue you are seeing.
