Why do we use the semilogarithm graph to plot the grain size

Why do we use the semi-logarithm graph to plot the grain size distribution curve and the liquid limit determination curve?

Solution

1. To plot wide range of data

2. To get stright lines from this we can get slope value easily

3. If you observe the ranges of sieve sizes (4.75 mm to 0.075 mm) which are not possible to draw this values in noraml graph so that we use this semi-logarithm graph
