Dalam [[sains]] dan [[perekayasaan]], '''grafik log-log''' adalah grafik data numerik dua-dimensi yang menggunakan [[skala logaritmik]] pada sumbu horizontal dan vertikalnya. [[Perpangkatan|Fungsi pangkat]] – hubungan-hubungan dari <math>y=ax^k</math> – hadir sebagai garis-garis lurus pada grafik log-log, dengan eksponen yang menyamai landaian, dan koefisien yang setara dengan intersep (perpotongan). Oleh karena itu, grafik semacam ini sangat berguna untuk mengenal hubungan-hubungan ini dan [[Teori estimasi|memperkirakan parameter-parameter]]. Basis apapun dapat digunakan untuk logaritmanya, dengan basis-10 (log umum) menjadi yang paling umum digunakan.
In [[science]] and [[engineering]], a '''log–log graph''' or '''log–log plot''' is a two-dimensional graph of numerical data that uses [[logarithmic scale]]s on both the horizontal and vertical axes. [[Exponentiation#Power_functions|Power functions]] – relationships of the form <math>y=ax^k</math> – appear as straight lines in a log–log graph, with the exponent corresponding to the slope, and the coefficient corresponding to the intercept. Thus these graphs are very useful for recognizing these relationships and [[estimating parameters]]. Any base can be used for the logarithm, though most commonly base 10 (common logs) are used.
