A method to visualize numerically calculated density and temperature evolutions of heating calculations is presented simulating the soft x-ray observations of the soft x-ray telescope aboard the Yohkoh satellite. The visualization method is applied to two different model calculations of the heating of coronal magnetic loops by the resonant absorption of Alfven waves. For these two cases, information on the variations of temperature and density can be extracted conveniently from the generated images. The resulting images reveal features that are characteristic of the resonant absorption process. This suggests that signatures of resonant absorption can be extracted from real soft x-ray observations of coronal loops.
