Override the CSS with your custom attributes:
.your-div-class .nv-series:nth-child(1){ transform: translate(0, 0); }
.your-div-class .nv-series:nth-child(2){ transform: translate(0, 20px); }
.your-div-class .nv-series:nth-child(3){ transform: translate(0, 40px); }
.your-div-class .nv-series:nth-child(4){ transform: translate(0, 60px); }
.your-div-class .nv-series:nth-child(5){ transform: translate(0, 80px); }
.your-div-class .nv-series:nth-child(6){ transform: translate(0, 100px); }
.your-div-class .nv-series:nth-child(7){ transform: translate(0, 120px); }
.your-div-class .nv-legend{ transform: translate(180px, 150px); }
.your-div-class .nv-legendWrap{ transform: translate(-80px, 70px); }
your-div-class refers to the class applied to the div container which contains your chart directive. Change the translate(0, 0) property with your (x, y) pixel values.
