overlap

I've been googling around, but I can't seem to grasp this. My situation is that the countries overlap when presented on the pie chart: This is an example of what is happening: jsfiddle I am a total beginner to D3 and am trying to prevent text overlap. Is there like a text margin attribute that I can add such that my labels don't overlap each other? musically_ut Update : See the answer to D3 put arc labels in a Pie Chart if there is enough space for a more comprehensive solution. I do not know any generic method of laying text elements such that they do not overlap. However, there is a

Anyone could help me in a query that **merge a interval of datas? ex: Common select: SELECT id, date_start, date_end FROM evento ORDER BY date_start I GOT THIS: FROM THIS: but a want a query that return this: 01 - 2013-10-11 08:00:00 2013-10-11 15:00:00 02 - 2013-10-11 16:00:00 2013-10-11 19:00:00 Thanks a lot! You may also try this query (once more solutions beside those given by PM 77-1 in the comment above) : WITH RECURSIVE cte( id, date_start, date_end ) AS ( SELECT id, date_start, date_end FROM evento UNION SELECT e.id, least( c.date_start, e.date_start ), greatest( c.date_end, e.date_end

I am writing a designer that enables the user to drag controls around the screen. What would be the best way of detecting if a control is overlapping another control while i am dragging the one control around? Should i just get the dimensions of the FrameworkElement and keep on checking the dimensions of the other elements? Thanks. Eli bitbonk The dimension (FrameworkElement.ActualWidth FrameworkElement.ActualHeight) and postion (Canvas.Top, Canvas.Bottom,Canvas.Left, Canvas.Right) of your elements would suffice if they are always rectangular. In that case you can easily calculate if two

Making a barplot the 'standard' way dat <- read.table(text = "A B + 1 1 4 + 2 2 3 + 3 3 2 + 4 4 1", header = TRUE) barplot(as.matrix(dat)) gives a barplot like this: Instead, I would like to have the different segnments to overlap, like so How can I make such a plot in R? There are two ways I have used: (counts <- with(diamonds, table(cut, clarity))) # clarity # cut I1 SI2 SI1 VS2 VS1 VVS2 VVS1 IF # Fair 210 466 408 261 170 69 17 9 # Good 96 1081 1560 978 648 286 186 71 # Very Good 84 2100 3240 2591 1775 1235 789 268 # Premium 205 2949 3575 3357 1989 870 616 230 # Ideal 146 2598 4282 5071 3589

I have the following table: +-----------+-----------+------------+----------+ | id | user_id | start_date | end_date | | (integer) | (integer) | (date) | (date) | +-----------+-----------+------------+----------+ Fields start_date and end_date are holding date values like YYYY-MM-DD . An entry from this table can look like this: (1, 120, 2012-04-09, 2012-04-13) . I have to write a query that can fetch all the results matching a certain period. The problem is that if I want to fetch results from 2012-01-01 to 2012-04-12 , I get 0 results even though there is an entry with start_date = "2012-04

I have a huge input file (a representative sample of which is shown below as input ): > input CT1 CT2 CT3 1 chr1:200-400 chr1:250-450 chr1:400-800 2 chr1:800-970 chr2:200-500 chr1:700-870 3 chr2:300-700 chr2:600-1000 chr2:700-1400 I want to process it by following some rules (described below) so that I get an output like: > output CT1 CT2 CT3 chr1:200-400 1 1 0 chr1:800-970 1 0 0 chr2:300-700 1 1 0 chr1:250-450 1 1 0 chr2:200-500 1 1 0 chr2:600-1000 0 1 1 chr1:400-800 0 0 1 chr1:700-870 0 1 1 chr2:700-1400 0 1 1 Rules: Take every index (the first in this case is chr1:200-400 ), see if it
