svg - Draw line with d3.js using separate, fixed x & y input arrays -


I have different x and y arrays and want to connect the dots using a line path. This is about the simplest possible example, but I do not mess much about writing the function. Here's my code: 

  & lt ;! DOCTYPE html & gt; & Lt; Meta charset = "UTF-8" & gt; & Lt; Body & gt; & Lt; Script src = "http://d3js.org/d3.v3.min.js"> & Lt; / Script & gt; & Lt; Script & gt; Var margin = {top: 20, right: 20, bottom: 20, left: 20}, width = 600 - margin. Left - margin. Right, height = 270 - margin.Top - margin.bottom; Var xdata = d3.range (20); Var ydata = [1, 4, 5, 9, 10, 14, 15, 15, 11, 10, 5, 5, 4, 8, 7, 5, 5, 5, 8, 10]; Var xscl = d3.scale.linear () .domain (d3.extent (xdata)). Ranges ([0, width]) var yscl = d3.scale.linear () .domain (d3.extent (ydata)). Range ([height, 0]) var slice = d3.svg.line () .x (function (d) {return xscl (xdata [d]);}) .y (function (d) {return yscl (ydata [ ("Width", width + margin.left + margin.right) .attr ("height", height + margin.top + margin.bottom) svg.append ("path") .attr ("class", "line" ) .attr ("d", piece) & lt; / script> & lt; / body & gt;   
 but it returns an error  Uncount Type error: The property 'length' of the undefined  can not be read, hence  d3.svg.line) is not the correct form of  is wrong? I do not pray any typo   
 
 
 Based on the location of the article  d3.svg.line , I think it is difficult to know about this function without the array expected. Therefore:  
  var xy = []; (var i = 0; i & lt; xdata. Length; i ++) {xy.push ({x: xdata [i], y: ydata [i]});}   
 I  .domain  and  fragment  have other changes related to the function. Here are the results of my efforts.

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...
