Geo Charts Basic

1. Who can create a map chart and what do you need?

Any Zoho Analytics user who wishes to visualize geographical data can create this chart. You will need a location-specific data column to create this chart.

2. What kind of data can be visualized in map charts?

If your dataset contains location information (say, country, county, city etc) then you can use map charts to visualize your data. Zoho Analytics will auto-identify the columns types while importing and set the corresponding Geo data type. Currently, Zoho Analytics can auto-identify five types of Geo data.   

• Continent - If your column contains the names of the continents
• Country - If your column contains the names of countries
• County - If your column contains the names of counties 
• State/Province - If your column contains the names of states/provinces
• City - If your column contains the names of cities
• Zip Code - If your column contains postal code of locations
• Latitude and Longitude - If your column contains latitude and longitude of locations
• Airport - If your column contains airport IATA code

3. Will Zoho Analytics automatically identify the Geo data?

Yes. When you import the data into Zoho Analytics, if your dataset contains a geographical column (continent, country, county, state or city) it will be automatically set to the corresponding Geo data type. 

In case your dataset contains a latitude, longitude or zip code data, you will have to manually change the data type to a Geo-location either at the time of import or later, using the Change Data Type option. Refer to this question to learn how.

4. How do I set the data type of a column as Geo?

When you import the data into Zoho Analytics, if your dataset contains a geographical column (continent, country, state, city or district) it will be automatically set to the corresponding Geo data type. If your existing table contains a geographical column and you wish to change the data type,

• Right-click the column header and select Change Data Type
• Select the correct Geo data type from the Data Type drop-down
• Click OK

5. I have Latitude and Longitude specific information in my dataset, can I create a map chart using that?

Yes, you can. To create map chart using latitude and longitudes, you need both latitude and longitude data as different columns in your dataset and set the data type of the columns to Latitude/Longitude.  

Follow the steps below to change the data type of your column. 

1. Right-click the column name and select Change Data Type. 
2. Select the Latitude/Longitude from the drop-down.
3. Click OK.
   

Once you have set the data type as latitude and longitude, you can create reports using this. 

6. I have postal zip code in my dataset, can I create a map chart using that?

Yes, you can. To create a chart using this you need to change the data type of the column to Zip code.  

Follow the below steps to change the data type of your column to Zip Code. 

1. Right-click the column name and select Change Data Type. 
2. Select the Zip Cope from the drop-down.
3. Click OK.

Once you have set the data type as Zip Code, you can create reports using this. 

7. I have airport IATA code in my dataset, can I create a map chart using that?

Yes, you can. Zoho Analytics will automatically identify your data as IATA code. In case it is not identified, you need to change the data type of the column to Airport.  

Follow the below steps to change the data type of your column to Airport. 

1. Right-click the column name and select Change Data Type. 
2. Select the Airport from the drop-down.
3. Click OK.

Once you have set the data type as Airport. You can create reports using this. 

8. What are unresolved locations and from where do I access the list?

When you plot a map chart, sometimes Zoho Analytics might not plot all the data points in the map. This could be due to issues in resolving the geo location such as duplicated/ambiguous location names, misspelled locations, the colloquial name for places etc.

When Zoho Analytics is not able to identify a location, it is listed as an Unresolved Location(s) for the user to rectify the issue. You can find the list of unresolved locations by clicking the Unresolved Location(s) icon that appears in the Map toolbar when you mouse over the chart in the Edit Mode. Refer to the next question to learn about resolving them.

9. I have created a map chart but there are some unresolved locations, how do I resolve them?

Unresolved locations, as mentioned in the previous question, are Geo locations (places) that Zoho Analytics is unable to identify. You can help Zoho Analytics to resolve them, by providing the required/missing information, as described in the below steps.

Resolving through Geo Column Mapping

Mapping it to a country column: This will allow Zoho Analytics to identify the country in which the unresolved place is located and plot it appropriately. If you have a country column in your data-set, you can map it to resolve the unresolved locations.

In case you do not have a country column, but all the state/cities belong to a single country, you can use Provide the Location option and enter the name of the country. 

Mapping it to a state column: This is in addition to mapping the location to a country column. If your dataset contains a state column further mapping it to a state column will help Zoho Analytics identify the state in which the unresolved location is located. 

In case you do not have a state column, but all the cities belong to a single state, you can enter the name of the state by selecting Provide the Location option as described above in the case of a country. 

Correcting Misspelt Locations

Zoho Analytics will not be able to identify the location if the spelling of the location is not correct. For example., Hong Kong spelled as Hongkong or Brooklyn being spelled as Broklyn.

In this case, we recommend you to correct the spelling either in the original data and then import it into Zoho Analytics, or make the necessary corrections in the Zoho Analytics table. 

Plotting the Latitude and Longitude

You can also resolve the issues by specifying the latitude and the longitude values of the corresponding location from the unresolved locations page.

Pick the Location

You can also pick the location by clicking the Pick Location link. Search for the location in the map using the given search field. Place the picker in the correct Geo location in the map and click Apply. The latitude and the longitude values for the selected location will be auto-filled in the respective fields.
