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

Any Zoho Advanced 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 Advanced Analytics will auto-identify the types of the columns while importing and set the corresponding Geo data type. Currently, Zoho Advanced Analytics can auto-identify 5 types of Geodata.   

• 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 Advanced Analytics automatically identify the Geodata?

Yes. When you import the data into Zoho Advanced 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 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. Learn how.

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

When you import the data into Zoho Advanced 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,

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

​5. I get an error message "Invalid GEO LOCATION" while importing geodata into Zoho Advanced Analytics. How do I resolve them?

This error message will be displayed when your geo data contains duplicated/ambiguous location names, misspelled locations, colloquial names for places, etc. You can resolve these issues from the imported table or from the geo map chart. Learn more.

6. 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 below steps 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. 

7. 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. 

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

Yes, Zoho Advanced Analytics will automatically identify your data as IATA code. In case it is not identified, then 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. 

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

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

When Zoho Advanced Analytics is not able to identify a location, it lists it as an Unresolved Location(s) for the user to rectify the issue. You can find the list of unresolved locations by:

From a Table

Right-clicking the geo column from your table and select Set Geo Hierarchy from the drop-down. 

From a Map Chart

Clicking the Unresolved Location(s) icon that appears in the Map toolbar when you mouse over the chart in the Edit Mode.

10. 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 Advanced Analytics is not able to identify. You can help Zoho Advanced 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 Advanced 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 states/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 Advanced 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 Advanced 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 Advanced Analytics or make the necessary corrections in the Zoho Advanced 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 in the unresolved locations page.

Pick the Location

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

Creating Geo Charts

1. What are the supported map chart types?  

Currently, Zoho Advanced Analytics supports the following types of map charts,  

• Map Scatter
• Map Bubble
• Map Pie
• Map Bubble Pie
• Map Filled  
• Geo Heat Map

Zoho Advanced Analytics will auto-identify the appropriate Geo Map type from the columns used in the chart. You can also choose to change the chart type using the Other Charts option.  

2. How do I create a map chart?

You can create a map chart by dragging and dropping a geographical column (a column of type "Geo") into the X- Axis shelf and the required columns in other shelves.  The below animation shows how to create a map chart.

3. Can I create a map chart for specific countries alone and hide the rest of the map?

Yes, you can create a map chart for specific countries alone by selecting the country-specific map. You can change the map type from the Maps tab of the Settings page.

The below animation shows you how to create a chart over specific countries. 

4. How do I create a map chart using the latitude and longitude columns?

To create a map chart using the latitude and longitude information, you need to ensure that the data type of the column is set to Latitude and Longitude. Refer to this section to learn how.

The below animation shows you how to create a chart using Latitude and Longitude data. In this chart, we have plotted the total profit gained in a location grouped by product category.

6. How do I create a map chart using the Airport information (IATA Code)?

To create a map chart using the airport information (IATA code), you need to ensure that the data type of the column is set Airport. Learn how.

The below animation shows how to create a chart using Airport data. This chart plots the busiest airports in the US, based on the number of flights per day. 

7. I have a column whose data-type I do not want to change to "Geo". Can I still create a map chart using it?

Yes, you can do it using the Treat as Geo option in the chart designer. When you use this option data type of the column used in creating the report will be considered as a Geo Data Type only for that particular report.

In the below animation, the column 'State' is of string data type. We have created a map chart using this column by using the option 'Treat as Geo'.
