javascript - Changing Raphael arc starting position -


I am trying to draw a percentage of a circle clockwise to use the Raphael javascript library, while the initial position Specifying the

Right now I have been able to start it clockwise by clockwise clockwise and using the code below at 6 o'clock position, but I want to start drawing at 4 o'clock position (or I specify the ideal In any case). 

  var zodiac = 75; Var archtype = rafael ("canvas", 500, 500); Archtype.customAttributes.arc = function (xloc, yloc, value, total, R) {var alpha = 360 / total * value, a = (-90 - alpha) * Math.PI / 180, x = xloc - R * Math .cos (a), y = yloc - R * Math.sin (a), path; Console.log ('x -' + x); Console.log ('y -' + y); If (total == value) {path = [["m", xlok, yolok-r], ["a", r, r, 0, 1, 1, xlok-0.01, yolok-r]]; } Other {path = [["m", xlok, yolok + r], ["a", r, r, 0, + (alpha> 180), 0, x, y]]; } Return {path: path}; }; Var my_arc = archtype.path (). Ether ({"stroke": "# 00a5ff", "stroke-width": 14, arc: [90, 90, 0, 100, 80]}); My_arc.animate ({Arc: [90, 90, zodiac, 100, 80]}, 1500);   
 I'm just using the Raphael library and really appreciate any help.  
 thanks   
 
 
 simply found the  .rotate  function . The following code will rotate circle-45 degrees which will start at 4 o'clock position. I think you will need to use the  transform  function in Raphael v2.  
  my_arc.rotate (-45, 90, 90) Value ({Arc: [90, 90, zodiac, 100, 80]}, 1500);

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
