Thanks rborchert. I tried your suggestion and it partly works; that is, I still cannot show what I intend to show. Let me explain a little more. Say I have a line shapefile with 3 records and a field call "Loss". Record1 has 2 in Loss; Record2 has 6 in Loss; and Record 3 has 1 in Loss.
I am looking for a symbology that would show the lines like a the simple railroad symbol, but with the number of ties (hash) dependent on the value of the field Loss, regardless of the length of the line or the scale of the display. So the line representing Record1 should be a line 2 hash marks evenly distributed along its whole length ---+-----+---; Record2 should be a line with 6 hash marks evenly distributed along its length -+--+--+--+--+--+-; Record3 should be a line with 1 hash mark in the middle ------+------.
The software (running in ArcGIS) generating the value for Loss can be temporal; that is, give hourly results for the whole duration of the simulation. The value of Loss at every hour is different. The software can skip to any hour and dynamically change the value of Loss.
Is it possible to make a symbol for a line with the number of "decorations" (ties, hash, etc.) dependent on a field/attribute value?
Thanks for you help and patience. And to everyone giving me pointers.
