How I can plot average line on cdf plots?
data_cellular = readmatrix('tmobile5gmain.csv', 'Delimiter', ',', 'LineEnding', '\n');
data_cellularb = readmatrix('att5gmain.csv', 'Delimiter', ',', 'LineEnding', '\n');
fig = figure();
y_c = data_cellular(:, 2);
%y_u = data_cellularb(:, 3)
hold on;
y_h = data_cellularb(:, 2);
hold on;
c1 = cdfplot(y_c);
hold on;
c2 = cdfplot(y_h);
hold on;
%set(gca, 'XScale', 'log')
%c2 = cdfplot(y_u);
nbins = 50;
dist = 'Normal';

Hi Arijet,
I understand that you want to plot an average line on the CDF plots mentioned.
To implement this, kindly refer to the following steps:
  • Compute the Cumulative Distribution Function (CDF) for each dataset using the “cdfplot” function, as you have already done for “y_c” and “y_h”.
  • Calculate the average values for each dataset using the “mean” function and name them as “avg_c” and “avg_h”.
avg_c = mean(y_c);
avg_h = mean(y_h);
  • Plot the average lines on the CDF plots using the “line” function. Specify the x-values as the average values and the y-values as [0 1] to span the entire range of the CDF plot.
line([avg_c avg_c], [0 1], 'Color', 'red', 'LineStyle', '--');
line([avg_h avg_h], [0 1], 'Color', 'blue', 'LineStyle', '--');
For more information regarding the “cdfplot”, “mean” and “line” functions, kindly refer to the following documentation:
https://www.mathworks.com/help/stats/cdfplot.html
https://www.mathworks.com/help/matlab/ref/mean.html
https://www.mathworks.com/help/matlab/ref/line.html
I hope this answer provides you with the required information regarding your query.
Regards,
Nithin Kumar.
