Graduated color symbols are used to show a quantitative difference between mapped features by varying the color of the symbols. Data is classified into ranges that are each assigned a different color from a color scheme to represent the range.
Representation of the data that varies in the magnitude of a phenomenon is efficient. It helps the user to track the differences with respect to the locations, have a deeper insight into the trends, and ease the analysis and conclusion from the data visualization.
BStreams Graduated map helps you to visualize your trends in the format of a map. If your data contains a trend also, it is associated with location, you can easily facilitate your dashboard with graduated color maps, with a variety of amazing features.
When to use a Graduated color map?
When it comes to classifying your data in a matter of range of colors associated with specific locations, you can use the Graduated color map. The graduated color maps can be used when the phenomenon in your data is going to change in the order of different magnitude and you wish to represent the changes to convey the differences in your data to the users.
For instance, the mean temperature in one month in different locations, the variation of sales for specific products in different spots, and many other use cases that require the demonstration of changes with respect to a specific area can be an excellent use of a graduated color map.
In-depth the graduated color will assign a color considering all the available ranges in your metric to a specific region. Although symbol color is applied from a color scheme, BStreams provide the feature for you to modify all your classes with your desired colors.
What more do you need to know?
For visualizing the variation of data on a map, you need to know your data is assigned to exactly which specific location. The location is represented as a shape file in your map with different divisions.
BStreams has an archive full of different maps from all around the world in different administrative divisions, therefore you just need to know which type of division is adequate for your data visualization.
For instance, it really depends on the distribution of your data on a geographical scale:
- World
- Continent
- Specific regions
- Country
- Administrative division of
- Countries i.e Province,
- State, Regions, Cantons,
- District etc.
How to create a Graduated Color map on BStreams?
Bear in mind for the creation of any map on BStreams you need to have the coordinates associated with your data. You can find the Graduated Color map in the chart panel. After choosing your dataset you can simply follow these easy steps:
- Select the map to which you wish to assign your data.
- Choose Latitude and Longitude from the Coordinate section.
- Select a metric from your fields or create a new one. Note that the metric that you selected is the data that you wish to represent as a matter of a graduated color map.
- Click the Apply button and your visualization is ready.
For more customization, you can navigate through the Style panel.
We provide some hints for your customization:
Show popup
The popup is considered as the label for your markers that allows you to represent more information about your data (check the bstreams above and click on states to see it). On the Data panel just toggle the button show popup. You can visualize Table, Line, and Bar charts for each area. Select which type of charts you wish to add to the popup window, select the dimension and metric regarded and click the Apply button.
The BStreams is intelligent to link your charts to the areas. The algorithm demonstrates any related rows of the data that have the coordinates belonging to a specific region.
Troubleshooting
Here below you can find some problems that have been collected based on the user experiences, and suggested solutions:
Why does the graduated map that I made have no colors? Investigate the dataset that you choose to understand which specific map you want to visualize. It is important to know that you select the correct map based on your metric. Furthermore, if the map has been chosen correctly, probably the range of your metric is not big enough in terms of the specific map that you selected, and the regions did not receive any color. Try to change the classes manually by the Color palette in the Style panel.
I need a specific map, but it’s not available. What can I do? If you need a specific map for your data visualization, and you did not find it in the map section, please do not hesitate to contact us at support@bstreams.io
Why are some of the popup windows empty? The algorithm will collect the data regarding each shapefile. For example, one province has 50 rows of data assigned to it, but the data is not visualized completely on the popup window. You need to check whether the coordinates regarding the rows of data are correct or not. The algorithm behind the BStreams checks that each row of your chosen field belongs inside of the shapefile or not then represents the data.
