Google maps in QV

[Anonymous]

Hi,

I've tried to build an app with a Google Maps object in it. I followed the steps that are provided in most posts about this subject.

Somehow it still doesn't work. See attached file.

Can someone please help?!

Kind regards.

Hi Rajesh,

Thank you for your response.

I don't have the variable 'GDP_PPP_M'. Can you tell me what the value of this expression must be?

Thanks.

Hi,

First change ',' by '.' in = SET DecimalSep='.';

your coordinate use a dot as decimal.

Then go to the color panel and enter in dynamic picture :

='http://maps.google.fr/staticmap?center='
&
num(var_mid_lat, '##############', '.', ',' )
&
','
&
num(var_mid_long, '##############', '.', ',' )
&
'&zoom=$(var_zoom)'
&
'&maptype='&var_maptype
&
'&size='&map_size_x&'x'&map_size_y
&
'&key='&gmap_key & '.jpg'

GDP_PPP_M ? you find it in the backgroung color for longitude :

=argb(150,round(250*GDP_PPP_M/max(total GDP_PPP_M)),0,0)

It's used to set a color for each circle depending of the value of GDP
