Graph Analysis Graph Analysis When you observe the data you have obtained graphically and numerically, you can figure out whether there is any variability in the scan result. The meanings of the colors in the graph obtained as a result of scanning are as follow: Red: Metallic objects and objects with high magne�c effect. - Page 27 Graph Analysis The metallic objects have an obvious shape whereas the minerals are usually sca�ered and diffused. The metallic objects are red, mineral structures are usually yellow and orange. The most important feature of the metallic objects that dis�nguishes them from minerals is that there is a certain numeric difference from the soil according to the obtained data.
- Page 28 Graph Analysis In the Cavity data: Underground cavi�es such as tunnels, chambers, and tombs that have been ar�ficially created are shown in blue in the graphic. In case there is any kind of subsidence or earth fill inside the underground cavity, the cavity data will be light blue, turquoise and light green.

Saludos, respecto al icono datos, es necesario que los valores sean a mas de 200 puntos para que un objeto sea positivo, quiero decir por ejemplo metalico? Por que en las tomas que he realizado, lo maximo que me ha subido es entre 79 y 144 puntos, osea que no lo puedo tomar como positivo para metal?
