Adding numbers to your maps

As we talked about on April 4th, it is possible to overlay numbers on your maps in order to guide the user’s experience more (refer to the Chancellorsville exhibit for an example of this). This is done by plotting a point, and then replacing it with a graphic.

  1. Log-in and open the Neatline Editor for your exhibit.
  2. Create a New Record and give it an appropriate title (e.g. “Number One”).
  3. Click on the new record, and then select the point tool in the map window (the pencil with the plus-sign) and click it once on the map to insert a point (you can move it later if need be).
  4. In the Item Editor, navigate to Styling.
  5. Look for the box entitled Point Graphic. Copy and paste this address into the box: http://warfare.beloitmaps.com/images/1.png
  6. Save.
  7. A black ‘1’ should replace the point on your map, but it will be quite tiny. You can change the size of the graphic by increasing or decreasing the value for Point Radius in the Item Editor.
  8. You can also alter the opacity by changing the value for Graphic Opacity.

I have created two sets of number graphics from 0–9 in both black and white. You can pull them into Neatline by entering the address “http://warfare.beloitmaps.com/images/x.png” in the Point Graphic box, where “x” should be replaced with the number you want to appear (e.g. “http://warfare.beloitmaps.com/images/8.png” will pull in a black 8). If you want white numbers instead, add a “w” before the number (e.g. “http://warfare.beloitmaps.com/images/w8.png” will pull in a white 8).

As we saw on Thursday, you can also use this feature to pull in other external graphics to represent a point, and people had already started exploring the potential of that feature. Just be aware that those graphics will scale with the map view (i.e. the graphics always appear the same size to the viewer, whereas shapes get smaller and bigger depending on the zoom level).

Have fun!
