Dear All, I want to plot a simple cumulative probability distribution graph with like the attached screenshot. But I couldn't fix the y-axis scale as in that screenshot. My data details are follows: *y_values =c(66.78149,76.10846,81.65518,85.06448,87.61703,89.61314,91.20297,92.36884,93.64070,94.57693,95.23052,95.75163,96.15792,96.58188,96.97933,97.29730,97.59760,97.91556,98.14520,98.37485,98.57799,98.74580,98.87829,99.06377,99.16093,99.25808,99.37290,99.45239,99.54072,99.59371,99.62904,99.66437,99.69970,99.70853,99.72620,99.73503,99.77036,99.79686,99.80569,99.82335,99.83219,99.84985,99.86751,99.87635,99.87635,99.90284,99.90284,99.90284,99.91168,99.92051,99.92051,99.93817,99.93817,99.93817,99.95584,99.95584,99.97350,99.97350,99.97350,99.97350,99.97350,99.97350,99.97350)* *x_value=seq(63)* Thank you all in advance Dileepkumar R
