Map Size Displayed

Hi,

I'm trying to use Google Maps with QlikView and I'd like to change the size of the map that is shown on the display. It's not about the zoom, but the size that is displayed.

Please, could someone help me?

I'd follow the example of script as we can see below:

// Google Maps in QlikView

// V0.85.2 - October 1st 2008  © Copyright QlikTech International AB 2008 / AES

// Google Maps Key

// get a key here http://code.google.com/apis/maps/signup.html

//gmap_key = 'xx';

max_zoom_level = 17; //maximum value 17

// Variables required for calculating map

// No need to change these

var_pi180=                    '=pi()/180';

var_lat_offset=          '0';

var_mc2=                    '=256*pow(2,$(var_zoom))';

var_mc1=                    '=256*pow(2,($(var_zoom)-1))';

var_mid_lat=          '=min(latitude)+(1+var_lat_offset)*((max(latitude)-min(latitude))/2)';

var_mid_long=          '=min(longitude)+(max(longitude)-min(longitude))/2';

var_zoom=                    '=max(aggr(if(max( round(256*pow(2,(_zoom_level -1)))+( longitude  *((256*pow(2,_zoom_level ))/360)) )-min( round(256*pow(2,(_zoom_level -1)))+( longitude  *((256*pow(2,_zoom_level ))/360)) ) <map_size_x AND max((256*pow(2,(_zoom_level-1)))+((0.5*log((1+(sin((latitude)*pi()/180)))/(1-(sin((latitude)*pi()/180)))))*((-256*pow(2,_zoom_level))/(2*pi()))))-min((256*pow(2,(_zoom_level-1)))+((0.5*log((1+(sin((latitude)*pi()/180)))/(1-(sin((latitude)*pi()/180)))))*((-256*pow(2,_zoom_level))/(2*pi()))))<map_size_y,_zoom_level,1),_zoom_level))';

var_maptype=          '=if(isnull(only(maptype)),fieldvalue( '&chr(39)&'maptype'&chr(39)&', 1 ),maptype)';

map_size_x=              '640';

map_size_y=     '400';

SET HidePrefix='_' ;

// Field required for calcualting best zoom level

_zoom_level:

Load RecNo( ) as _zoom_level autogenerate(max_zoom_level);

maptype:

LOAD * INLINE [

    maptype

    roadmap

          mobile

          satellite

          terrain

          hybrid

];

Thanks to everyone who helps!
