@srisrim,
You can remove vertical and horizontal axis lines by setting lineThickness, gridThickness and tickLength to 0 for axisX and axisY as shown in the below code snippet.
axisX:{
lineThickness: 0,
tickThickness: 0
},
axisY:{
lineThickness: 0,
gridThickness: 0,
tickLength: 0
}
To make chart background as transparent, you can set backgroundColor property to transparent. Please take a look this JSFiddle for an example on chart with transparent background and without horizontal and vertical axis lines.
