shrink response data from database for diagram












0















im trying to shrink data in nodejs for a diagram, but have no ideas what would be the best way. i would like to create a function which gets the raw data and shrink the total value by X days as an example:



Data:



{ time: '2018-10-29', total: 8 }

{ time: '2018-10-30', total: 9 }

{ time: '2018-10-31', total: 10 }

{ time: '2018-11-1', total: 4 }

{ time: '2018-11-2', total: 21 }

{ time: '2018-11-3', total: 21 }

{ time: '2018-11-4', total: 4 }

{ time: '2018-11-5', total: 7 }

{ time: '2018-11-6', total: 14 }

{ time: '2018-11-7', total: 11 }

{ time: '2018-11-8', total: 15 }

{ time: '2018-11-9', total: 14 }

{ time: '2018-11-10', total: 23 }

{ time: '2018-11-11', total: 13 }

{ time: '2018-11-12', total: 6 }

{ time: '2018-11-13', total: 14 }

{ time: '2018-11-14', total: 17 }

{ time: '2018-11-15', total: 16 }

{ time: '2018-11-16', total: 16 }

{ time: '2018-11-17', total: 21 }

{ time: '2018-11-18', total: 6 }

{ time: '2018-11-19', total: 12 }

{ time: '2018-11-20', total: 11 }

{ time: '2018-11-21', total: 15 }

{ time: '2018-11-22', total: 15 }

{ time: '2018-11-23', total: 14 }

{ time: '2018-11-24', total: 25 }

{ time: '2018-11-25', total: 1 }


if i would like to shrink this data to 10 days it would be 28/10 = Math.round(2.8) so each 3 would be combined and return. but the question is how i get this to code.



thanks for any advice

          You could try something like this:



          const getDataInBucket = (bucketIndex, data) =>  data.filter((obj, i) => i >= bucketSize*bucketIndex && i<bucketSize*(bucketIndex+1));


          and then you can call it like that:



          getDataInBucket(0, data); // first 10 elements
          
getDataInBucket(1, data); // second 10 elements
          
getDataInBucket(2, data); // rest 8 elements

                    A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

                    Image
                    0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that?
