I have designed a treemap using highcharts with custom algorithm.It has a drilldown to 1 level. There is a drop down for my chart and it has two options for selection. treemap is displayed on the basis of dropdown selection which has a group by feature implemented using underscore.js library. The feature is working fine. But the problem is, all the tiles which are grouped together, are placed next to each other. My requirement is : i want all those tiles to be packed in one big tile with one label. something like header title in D3(exactly the same). Please let me know how to go about it. Is it something like treemap within a treemap? Also i wanted to know if its feasible to have different labels and tooltips for parent and children in the same treemap. any leads would be helpful.

I'm looking for a way to indicate key dates on a highchart with a label eg Public Holiday. I can't find a way to add labeled guidelines or add an opened callout to a point? Help appreciated.
In Highstock you have series type called flags which is a opened callout (similar to Dygraphs annotation). This is probably the closest fit to the indicators you referred. See this JSFiddle example of how it looks. Note how this example uses the Highstock source file, but builds a Highcharts chart. See this documentation for official information.
In Highcharts you can highlight points, labels and value in a wide variety of ways. First of you can add data labels to your points, which renders text next to it. Secondly you can use plot lines to highlight certain values along an axis. See this JSFiddle example of how both of these options can be used.
Of course there are lots of ways to improve and build upon this out of the box functionality, but that is up to your specific demands and desires.
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.
For a rails web application I need a timeline with on the top (stacked) bar charts and on the bottom single events that should be recognizably different using e.g. forms (squares, rhombus, circles) and colors.
It's also important that I get some kind of picture back in order to reuse it to build a pdf.
At the moment I do the bar chart part with google charts, but I can't find a way to do the events. Those could also be on a separate chart that I then align in html or the pdf.
have you ever try the highcharts.
Here is an example of time series with events made with amCharts: http://www.amcharts.com/stock-chart/stock-events/
You can have any number of graphs stacked on each other, if this is what you want to do.

I would like to fill the area between two serieses (when serieses cross each other). See below. I tried the 'arearange' chart type but it filled most of the chart with solid colors. I saw a similar question but I wanted to know if Highcharts supports what I want or I have to use the solution posted in that question.
Chart now:
What I want:
type:'arearange'
You need to use three series, first / second as lines, third as arearange with defined values.

I have a TPieSeries which looks like this image when populated with data. Not very bright... Can I instruct the pie series to show the top N most significant records, and summarize the rest in another slice named "Others"? So far, the only thing I've come up with has been to set chart paging and order my data so that the top N records are shown on the first page. I'm using TeeChart Standard v2011.03.32815 VCL.
Yes, you can do it using the OtherSlice property as shown in Yeray's example here.
