gettng slide bars to work with maps

[#1]

Hi,

I am using the script below to incorporate maps into my qlikview document.

// Google Maps Key

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

let

gmap_key = 'ABQIAAAA5bl62kS6z0rphaDWHORuGxS-1e5eBlFSI2yxODmWMQJWVmxijxTjxrIpt2HMUo_ORjaOHFqGULHSwA';

let

max_zoom_level = 14;

//maximum value 17

let

def_zoom_level = 1;

let

def_map_size = 800;

// Variables required for calculating map

// No need to change these

var_pi180= '=pi()/180';

let

let

var_lat_offset= '0';

let

var_long_offset= '-1';

let

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

let

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

let

var_mid_lat= '=median(Latitude)';

let

var_mid_long= '=median(Longitude)';

let

var_zoom= '=If(max(aggr(if(max( round(256*pow(2,(_zoom_level -1)))+( Longitude *((256*pow(2,_zoom_level;

let

var_maptype= '=if(isnull(only(maptype)),fieldvalue( '&chr(39)&'maptype'&chr(39)&', 4 ),maptype)';

I want to be able to use slider bars to zoom in and out, and to scroll left to right and scroll up and down. I believe it has something to do with a modification to the following:

let

let

var_mid_long= '=median(Longitude)'; var_mid_lat= '=median(Latitude)';

I have seen an example document posted on this forum for an example using the city of London (UK) at http://community.qlik.com/forums/p/16118/62649.aspx#62649

in this example, the user has the following in their script

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

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

I can't seem to figure out how to get scrolling to work on my document but it seems to work in the example like above.

can somebody offer some help??

I have the same issue here ...

Anyone has suggestions?

Found the solution ...

...
var_long_offset = '0';
...
var_mid_long= '=min(Longitude)+(1-var_long_offset)*((max(Longitude)-min(Longitude))/2)';...
...

Hopes this helps ... it did for me

It seems that when zooming in by selecting on the map some zooming is not working as I thought it would ...

Think the var_long_offset as used in my idea has to do with this ....

Got to research this further.
