Google Maps API

[Anonymous]

Hello,

I was looking some QV Dashboards and I found that I can insert a map with some information inside. How can I add this kind of object and associate the places with the information?

If anyone has a demo or some code, please let me know.

That will be great.

Thank you very much.

Hi Juan,

To make this happen first you need coordinates (longitude / latitude)  for your location.

See the sample attached file.

Hi Sokkorn,

I'm running at this time the Personal Edition so I can't open that example. I was looking at the table and I realized that I have to create something like that for Colombia.

Now, which option allows me to insert the map as well and associate it with the table

Thank you very much.

Hi Juan,

Let check my attached file again.

Or try this

SET ThousandSep=',';
SET DecimalSep='.';
SET MoneyThousandSep=',';
SET MoneyDecimalSep='.';
SET MoneyFormat='$#,##0.00;($#,##0.00)';
SET TimeFormat='h:mm:ss TT';
SET DateFormat='M/D/YYYY';
SET TimestampFormat='M/D/YYYY h:mm:ss[.fff] TT';
SET MonthNames='Jan;Feb;Mar;Apr;May;Jun;Jul;Aug;Sep;Oct;Nov;Dec';
SET DayNames='Mon;Tue;Wed;Thu;Fri;Sat;Sun';

2. Create List Box: maptype

Do let me know, if this one still cannot open the file.

Hello Sokkorn,

I am not able to open the document. Meanwhile I am going to use the code that you suggested.

Hi Juan,

Let try my script. Don't forget take my excel file and put it together with your qvw file.

Hello,

I was trying to use the code, I have my Excel sheet with Colombia's coordinates but I don't have any Google Maps API Key.

Is that necessary?

Hi

No more necessary, just put in your key anything you want !

Hello,

I've done everything you told me, with all that code... but I don't have any map in my scatter chart. Why could that happen?

If you can check my app i'll be glad.
