In this example we provide a first, step by step look at how to format areas in a drawing using the Style pane. We can specify the same formatting for all areas or use a field to automatically set formatting, a process usually known as thematic formatting.
User Interface Changes: Recent changes in the user interface have not yet been incorporated throughout the user manual. Many illustrations need to be updated:
We open a drawing that shows the regions of France as areas.
Opening the table for the drawing we see that each record has the name of the Region, a Number that gives the regional number and a Geom field containing the geometry of the area object for the region.
Right-clicking onto the Regions drawing in the Project pane and choosing Properties we can see the Properties dialog for the drawing shows the table from which it takes data and the name of the geom field in that table that provides geometry for each object.
To change the formatting of the drawing we click on the drawing window so it has the focus and then we choose the Style pane.
We click the Fill Color button for areas.
We choose a color from the resulting drop down menu. If we would like some other color we click More... to open the usual Windows color setting dialog that allows a choice of any color we want. For now we will choose one of the many default color options, a shade of blue.
The button changes color to the blue color selected, and immediately the drawing updates to use the specified shade of blue as the fill color for areas.
We can apply the above technique to specify any of the style properties shown in the Style pane for areas, lines or points. See the Example: Style Pane Quickstart topic for an example showing how we can change other style properties, or even multiple properties at once.
So far we have manually specified a color to use as the fill color for areas. If we like, we can use the contents of a field to guide a choice of colors so that the fill color for areas (or any other Style property) is set for each area individually depending upon the contents of a field for that specific area. Using the contents of a field to automatically set the format for each object is called thematic formatting.
To use thematic formatting for area fill color in our drawing, we click the Fill color button for areas, and then in the pull down menu for fields, initially captioned (no field selected), we choose the field we would like to guide formatting. The pull down menu will be loaded with all field names we can use in the drawing for thematic formatting.
We choose the Number field to use the region number to guide formatting.
The dialog will automatically adjust to show controls for thematic formatting, showing a default range of intervals in the intervals list pane. No formatting has as yet been specified so all the color wells show the same blue color. We will leave the default choice of 5 for the number of Breaks, that is, groupings of records. We will change the method from equal intervals to a different method.
Instead of equal intervals we choose the equal count method for grouping numbers. Thematic formatting is confusing if too many different ranges of colors are used, so usually drawings are formatted using a more limited number of colors for better intelligibility. The equal count method choose ranges so that approximately the same number of records fall into each grouping used for a color. The small number of regions does not evenly divide by five, so the number of regions in each interval will not be exactly the same, but instead will be approximately equal.
As soon as we choose the equal count method the intervals in the intervals list are automatically re-computed to new interval boundary values that result in approximately equal numbers of records within each interval. Since the number of records does not divide evenly into five intervals, some of the intervals will have different numbers of records.
To automatically color the intervals we will apply a palette. When we click on the Palette button, options for two sub-menus will appear, both of which provide a long list of palettes. We will use the Color Brewer sub-menu, choosing within that menu the CB Spectral palette.
The palette colors are immediately applied to the color wells. To apply that range of colors and intervals to the drawing we press Update Style.
The drawing is immediately recolored using the colors assigned to each range. Depending upon the Number value for each area's record, that is, the region number, it will be colored by the color assigned to the range within which that region number falls. Any exceptions to values in the intervals, such as NULLs, will be colored by the settings in the first interval.
If we open the drawing's Properties we see a new Style property has been added, with the value for that property specified in human-readable JSON form.
There are many formatting options besides fill color as illustrated above.
The three illustrations below show the same drawings as the illustration above, but with default formatting altered by using the Style pane and overall background color set using the Layers pane.
In the above illustration thematic formatting is used to control the Rotation of the point symbols, with thematic formatting also used to specify the fill color of areas. The Layers pane was used to set black background color for the drawings.
In the above illustration points are all set to use the same icon and color, with thematic formatting also used to specify the fill color of areas. The Layers pane was used to set light beige background color for the drawings.
In the above illustration points are all set to use the same icon and color. Points use a Rotation of 180 degrees to flip the triangle style used for points. To create dotted line style area borders, we style the borders of areas as dotted lines. The same color is used for area Color and Fill Color. The Layers pane was used to set light blue background color for the drawings.
In the above illustration we have changed the point icon to a square, which when used with a Rotation of 45 appears as a diamond.
Historical regions - The illustrations in this topic use data from the US government, which show the regions of France as they were before 1 January 2016, when regions in France were reduced from 22 to 13.

Example: Style Pane Quickstart - A tutorial introduction to using the Style pane to apply color, symbology, size and rotation to areas, lines and points in drawings.
Example: Format the Size of City Points by Population - A common GIS task is to format the size of points in a drawing based on some value. For example, the size of points that represent cities might be formatted based on the value of the city's population, with cities that have larger populations being marked by larger point icons. This is an example of thematic formatting and is easy to do using the Style dialog.
Example: Add, Delete and Edit Thematic Formatting Intervals - This topic provides a step by step example of adding, deleting and editing intervals in the Style dialog that are used for thematic formatting.
Example: Style Properties in the mfd_meta Table - Style properties for drawings such as colors for areas are stored in human readable JSON values as properties in the mfd_meta system table. This example shows how we can copy formatting from one drawing to another by simply copying values between records in the mfd_meta table.
Example: Formatting Tricks - The visualization capabilities of Manifold using Style can be exploited to provide many visual effects. This topic provides some examples of how to use Style in unexpected ways to create a range of more elaborate effects.
Example: How Not to Format a Drawing - When using Style to format a drawing it is a really bad idea to use the same color for objects that is used for the background color. It can also be a bad idea to use transparent color. This topic illustrates why.
