Map should show Australia by default and not the whole world map

[#1]

My data is just for the Australian post codes and I want the map to show only that. But not sure why it shows the entire world map.

it's difficult to solve if there are no sample.

But in longitude and latitude expression you should use variable like $(var_zoom), which defined as

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))';

for example latitude expression:

((256*pow(2,($(var_zoom)-1)))+((0.5*log((1+(sin((Latitude)*pi()/180)))/(1-(sin((Latitude)*pi()/180)))))*((-256*pow(2,$(var_zoom)))/(2*pi()))))

I have the var_zoom defined. I am attaching my qvw file. Please help.

Hi Sergey, I have the var_zoom defined that away. I am attaching my qvw file anyway. If you can help that would be great.

Thanks,

You have to set the default zoom at the median of longitude and latitude.

How?

[rajat2392]

How you have applied this map....

As the background or Google Map extension Object..??

[#8]

applied map already as the background. see the attachment.

I have not downloaded your app.

Try this

='http://maps.google.com/staticmap?center='

&

num(Min(Latitude)+((Max(Latitude)-Min(Latitude))/2), '##############', '.', ',' )

&

','

&

num(Min(Longitude)+((Max(Longitude)-Min(Longitude))/2), '##############', '.', ',' )

&

'&zoom=$(var_zoom)'

&

'&maptype='&var_maptype

&

'&size='&map_size_x&'x'&map_size_y

&

'&key='&gmap_key & '&.jpg'

check the bold lines in your background, set it as this. Change Latitude and Longitude with the name of the field in your context.
