r - How to position the plot legend outside the plot in the bottom-right -

-
Image
i'm using latest ggplot2 , p + theme(legend.position='right') . function theme documented , combining bottom , right doesn't seem possible. however, maybe there alternate way achieve this? you can use 2-element numeric vector position, like: p+theme(legend.position=c(0.85,0) the problem is , overlap plotting area. and if want force in 1 horizontal line, can add: p+guides(fill = guide_legend(nrow = 1)) edit i used plot.margin expand area @ bottom, can play parameters: p+ guides(fill = guide_legend(nrow = 1))+ theme(plot.margin=unit(c(1,1,4,0.5),"cm"))+ theme(legend.position=c(0.85,-0.7)) or p+ theme(plot.margin=unit(c(1,1,4,0.5),"cm"))+ theme(legend.position=c(0.85,-0.7) ) note using rstudio, when export image @ width*height don't legends, if drag , adjust view before exporting follows, works.

How to use tree-shaking with webpack 2 and typescript and angular 2? -

-
i have set webpack 2 angular , seems work. not seem though tree-shaking , since have app nothing, , vendor.js still 800+ kb. it seems there little information available on how turn tree-shaking on, understood it's automatically turned on es6 modules, not work es5. so? and importantly: how can apply tree-shaking typescript/angular2 webpack2? i have found nice repository examples on how this. as mentioned in there , in comments question, there apparently bugs prevent tree-shaking happening. seems mean it's not possible "target": "es5" . we can use es2015 , we'll need additional steps (e.g. via babel) compile es5 until browsers support it.

javascript - Ease time between firing specific number of timeouts in a specific period of time -

-
it's kind of math problem. want fire specific number of settimeout (the number based on array length) in specific period of time (say, 5 seconds). the first settimeout should start @ 0 sec. , last @ 5 sec. . timeouts between should start ease-in effect, each timeout starts faster. there's example ilustrates want achieve exactly. i'm struggling around line: next += timeperiod/3.52/(i+1); which works perfect in demo example (for timeperiod ), doesn't work different letters.length have used static number 3.52 . how calculate next ? var letters = [ 'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t' ]; var div = $('#container'); var timeperiod = 5000; // 5 seconds; var perletter = timeperiod/(letters.length-1); // gives equal time betwee...

i have 2 array of objects var arr1 = [{a:12},{d:14}] , var arr2 = [{b:15},{c:10}] , want following result : arr3 = [{a:12},{b:15},{c:10},{d:14}] i want add objects in arr2 @ position 2 of arr1. note order of a,b,c,d in arr3. how insert array of objects within array of objects @ specified position array.split() thanks in advance you use array#splice function#apply it. this allows insert array given array @ position. var arr1 = [{ a: 12 }, { d: 14 }], arr2 = [{ b: 15 }, { c: 10 }]; array.prototype.splice.apply(arr1, [1, 0].concat(arr2)); console.log(arr1); .as-console-wrapper { max-height: 100% !important; top: 0; }
