I have a question about adding data to attribute tables. I uploaded an Excel file into ArcMap (File -> Add data -> Add XY data). I chose the table from Excel that had the orientation data's latitude, longitude, strike and dip. From there, I made the data permanent by exporting the data into a shapefile. This shapefile was then added as a new layer to my map. From there, using the attribute table in the shapefile, I was able to plot data as points on my map using the latitude and longitude. Then, I changed the symbol from a dot to one representing strike and dip, added rotation to the symbols using the strike, and lastly, labeled the symbols using the dip. This process worked well and I had no problems.
Now, my problem is whenever I edit the attribute table and want to add more data to that table, the new data does not show up on my map and I don't understand why.
Do I need to add that data to the existing Excel document and then go through the same process?
