In a Highcharts column chart we'd like to highlight one value/sample by drawing its column a little bit wider... But this seems not to be possible, is it?
pointWidth only affects the whole series.
Maybe I could overlay a second series, but IMHO that's not a nice solution.
You can also use data attribute and modify width.
http://jsfiddle.net/cDvmy/2/
chart.series[0].data[0].graphic.attr({
width:50
});
I don't see any way to do this with the current API. As an equally not nice solution you could adjust the SVG after the plot is drawn:
// make fifth bar of first series wider
var bar = $($('.highcharts-series').children()[4]);
bar.attr('width',parseInt(bar.attr('width'))+20);
bar.attr('x',parseInt(bar.attr('x'))-10); // keep it centered
Fiddle here.

I need to remove color as this image is seems
this image
I have two different series.
I do not want to use area-stacked and arearange because that two different series is dynamic.
I had try by this http://jsfiddle.net/erzLp3n9/3/ but not working
By using negativeFillColor you can color the area if it is negative, which seems to be the problem with your second example.
See this fiddle.
Where I set plotOptions.area.negativeFillColor.
If you are wondering why they don't look like the same color, it is because the top one is 75% opacity, see Highcharts API.
Could you explain exactly why you do not want to use stacking? This option along with setting color of the second series to transparent gives desired effect.

In my bar chart the point range is not equally, so I want to draw different widths for bar chart using highchart. However, all the solution is to draw different series. I wonder is there any solution to hack the code and only change the pointwidth inside one series?
Here is a screenshot
The easiest way would be to change width property of a column SVG element.

I have a situation where I need to remove all margins from a highchart and remove the x/y axis so it fills a series of columns in a table completely.
I did that, no problem. Chart goes to the extremes as needed.
What I need now is that pesky yaxis I already removed...but displayed in a table cell outside of the existing highcharts object.
It would seem easy, as though I could just set the overflow property of yaxis to 'visible' and play with the offset...which would work however this would only work if I wanted to re-position the axis within the boundaries of the highchart object. I want him in a different cell entirely.
Is there anyone who has had experience in this situation? Is it going to require me to have a secondary highchart with only a y-axis?
Best answer gets a green check.
EDIT :: I now have dispersed each 'day' into their own column (more bars coming per day [scheduled,actual,etc...]). In order to keep the scales lined up, I manipulate the yAxis:max property and set them all to a derived value.
In the open column (currently w/ text Hourly Trends) is where I would put an additional highchart module with no series data but with the same min/max/tickInterval.
The next big leap will be to see the data is alive and changes w/ schedule. May have to start another thread for that one, no?
Create a new HC object with no data but only the yAxis (making sure it is the right scale, etc). Perhaps add the same series of data to it but hide the series? Add it to the location you want. This seems kludge and not very good practice. Each business use is different but why would you want this?
EDIT based on comment of business rules:
Why not come at this from a different direction and have the individual chart elements (the bars/points/etc) be a single point chart. This way you have one chart per column. You can then set up the yAxis to be text and not worry about the position. If we could see an example of the page layout and the desired result that would help.
In a candlestick graph i am building, the latest bar is cut-off partially such that even the bar is not visible. Thus it's difficult to judge the high and low by seeing the bar.
I'm unable to post a pic now but it's like the last rectangle being cut in half.
I'm tried a lot of options in the api but can't figure out why this is not showing correctly. The chart margin and axis offset options havent' helped. Is there a way i can set the series margin from the plot area so that it displays right.
For this problem, the best solution is to insert a dummy series which should be hidden from every aspect of the chart. So try this, insert a dummy series from the last point of the data series to some extra buffer(as per need). Then remove this series from the chart by explicitly removing it from the legends (using showinlegend),chart(setting linewidth to 0) and from tooltip by having a check in formatter. Hope this solves your problem.
I had the same problem and couldn't figure it out, because no matter how I changed the xAxis.maxPadding or changed the xAxis.max, it would always cut off the last candlestick when I clicked on the range selector.
To solve it, (hack) I just added an extra data point in my series and set it 1 day past the last day and set all values to null.
Without any code or a pic, it's hard to tell the problem, but it sounds like you need to use the max padding option. http://api.highcharts.com/highcharts#xAxis.maxPadding. You may also want to look at endOnTick as well as whether you are setting max on the axis.
long shot question here!
My chart has 3 views, in one of the views it shows the days of the month (1-31 etc)
My client wants to the highlight the Y-axis gridLines of days that are weekends, to be a darker color.
The other caveat is, I can't specify the stylistically different gridLines when creating the graph, only when I redraw the graph.
(Because this view isn't the initially view and I am redrawing me graph as the user navigates through the views.
ATM between redraws I am removing the old series, adding a new one, changing the chart title etc
Does anyone know how to do this?
While I think that #mg1075's solution of using the plot bands is the best way of doing this, if you wanted to get really crazy you can modify the gridlines through the dom. For example, make every other line red:
$.each($('.highcharts-grid path'),
function(i, elem) {
if (i % 2 != 0)
{
$(elem).attr('stroke','red');
}
});
});
Fiddle here.
