MapInfo Pro

How would I display a unique symbol to represent different quantitative values in the same tale? For example a value of 0-50 represented by a square point and a value of 51-100 represented by a star point?

One approach for this would be to use a Thematic map & select "Individual" type from Step 1 of 3. Then select a template for Point Values (not the default Region value).

I would use the Ranges and start by selecting any of the point ranges.

After selecting the correct numeric attribute for the thematic, I would then define custom ranges (in this case three ranges) and select the preferred style for each range. This is where I assign different shapes to the different bins in the thematic.

As an additional tip - with version 16.0 you can also set the visibility per individual bin in the Layer Control, to highlight the specific ranges that you are interested in showing for the moment.

?One of the lesser known features of MapInfo Pro is the ability to save a theme as a default in the .tab file.  Since styles can be saved in MapInfo Native type tables, some people have spent the time to hard code the styles in the table. This works fine and there are some MapBasic utilities  that make this even easier. 

However, there are some reasons not to do it this way and the biggest one is that the essence of what we do is to derive visualization clarity by marrying spatial and other data. So why not let your data derive your visualization? If you add a new point to the data and give it a value, or a value changes, why can't the software automatically change the visualization? This is what themes are all about. 

Without the feature I am talking about, the only way to save this theme is in a workspace.  But what if I use this table in many maps? I always want the values 1-50 displayed a certain way. In the dialog where you create the theme, check the Save as Default Theme View

You can also save a template if you like the styles you have created to be used for multiple data sets.

The next time you open the table, your theme will be displayed. (note that there is map preference that allows you to disable the theme from displaying. Make sure that is unchecked)
