I have plotted a wavefrom using excel file(i have shown it below). I have 7 other similar graphs like this. I need to find the waveform average of the this 8 graphs. The length of these graphs also different.

No, they are not in same length and they are in separate excel files if plotted they'll give similar graph. Sry, Im not allowed to share the file.

Do they have the same range on the x-axis?

Potentially something like this
data1 = randperm(randi([10 20]))'; %readmatrix('dataset1.csv');
data2 = randperm(randi([10 20]))'; %readmatrix('dataset2.csv');
data3 = randperm(randi([10 20]))'; %readmatrix('dataset3.csv');
data4 = randperm(randi([10 20]))'; %readmatrix('dataset4.csv');
data5 = randperm(randi([10 20]))'; %readmatrix('dataset5.csv');
data6 = randperm(randi([10 20]))'; %readmatrix('dataset6.csv');
data7 = randperm(randi([10 20]))'; %readmatrix('dataset7.csv');
max_num_datapoints = max([numel(data1),...
numel(data2),...
numel(data3),...
numel(data4),...
numel(data5),...
numel(data6),...
numel(data7)]);
alldata = zeros(max_num_datapoints, 7);
alldata(1:numel(data1), 1) = data1;
alldata(1:numel(data2), 2) = data2;
alldata(1:numel(data3), 3) = data3;
alldata(1:numel(data4), 4) = data4;
alldata(1:numel(data5), 5) = data5;
alldata(1:numel(data6), 6) = data6;
alldata(1:numel(data7), 7) = data7;
avgd = sum(alldata', "omitnan")' ./ (2-sum(isnan(alldata)')');
