# Semilog graph

Example of semilog graph y = 10 x {\ displaystyle y = 10 ^ {x}}! [{\ \ displaystyle y = 10 ^ {x}}] (https://wikimedia.org/api/rest_v1/media/math/render/svg/c203d0d9c7d43534b9747f07be8c31ae4c9ada34) (red line) is in a straight line, the logarithmic scale on the y axis Notice how to take the numerical value of

Semi logarithmic graph(Katasumusu gurufu, semilog graph) Is a graph in which one axis of a is a graduation (the vertical is often a logarithmic scale). Extremely wide range of data can be handled. The axis of the ordinary scale is made to the narrow range data, and the axis of the logarithmic scale is made for extremely wide range data.

Exponential

y = a b x + c {\ displaystyle y = a ^ {bx + c}}! [{\ \ displaystyle y = a ^ {bx + c}}] (https://wikimedia.org/api/rest_v1/media/math/render/svg/fa04cf6938a859a408029a22275f49b505318fe8) (A {\ displaystyle a} ! [a] (https://wikimedia.org/api/rest_v1/media/math/render/svg/ffd2487510aa438433a2579450ab2b3d557e5edc) Is a positive constant, b, c {\ displaystyle b, c}! [{\ \ Displaystyle b, c}] (https://wikimedia.org/api/rest_v1/media/math/render/svg/13a3dedbae67e261b39c755dc355b1407b3b19db) Is a constant), we take log a y = b x log a a + c log a {\ displaystyle \ log y = bx \ log a \ + c \ log a}! [{\ \ displaystyle \ log y = bx \ log a \ + c \ log a}] (https://wikimedia.org/api/rest_v1/media/math/render/svg/eaa3bf7f329f9f03680ffea9271c8a757dbc3dd6) . Therefore, if the horizontal axis is normal scale and the vertical axis is logarithmic scale, the graph (inclination b log a {\ displaystyle b \ log a} ! [{\ \ displaystyle b \ log a}] (https://wikimedia.org/api/rest_v1/media/math/render/svg/a50b20b9784e3620118665f5f88039fd93489fa8) , y-intercept c log a a {\ displaystyle c \ log a}! [{\ \ displaystyle c \ log a}] (https://wikimedia.org/api/rest_v1/media/math/render/svg/83f214fe15d92ede04c18a302c215ee3450f79a8) Of).

Application example

Similarly, it is effective to determine the value of the multiplier. Then is required.
