Add the following code to MapSVG > Menu > JavaScript > afterLoad:
function(){
var mapsvg = this;
if(MapSVG.isPhone){
mapsvg.viewBoxSetBySize(1, 2);
}
}
viewBoxSetBySize()
method sets the map width/height ratio.
The code above sets the height x2 times bigger than width.
If you want to make the map fullscreen, use the following code:
function(){
var mapsvg = this;
if(MapSVG.isPhone){
mapsvg.viewBoxSetBySize(jQuery(window).width(), jQuery(window).height());
}
}
