Dear Mathgroup, This question may have come up before and I searched the archives but could not find anything specific. This is new ground for me so I am a little lost on what options are available to me. I want to add cross-hairs to graphics so that I can navigate along a plot which is the result of say MultipleListPlot or ListPlot. Currently, I have just made functions that let me replot my plots close to the regions I'm interested in and I "guesstimate" the coordinates by drawing a fine grid. Another method I tried was a recursive algorithm using NestList to hone in on a particular value. Unfortunately the plots are not always smooth and well behaved in the region of interest. Cross-hairs would be a better option. Can someone point me in the right direction please. J/Link? ... but which way. Is there something that I can do from the Mathematica side or do I have to grab the numbers from Mathematica and re-draw it using a Java program. Thanks Yas
