If I have a dataset and I want to threshold it I use
thresh = find(dataset > 100)
however, if I want to plot 'thresh' how would I go about this as I know that the find function just gives the indicies at which these values occur.

If you want to plot the data above threshold, you can use
dataset_new = dataset(find(dataset > 100));
plot(dataset_new)

You need to put dataset_new on the left hand side:
x = Data_Bushing1(:, 1); % import Y of column 1 from Data_Bushing1
x(x > -2 & x < 2) = 0; % set values in between threshold value to zeros
dataset_new = x;
stem(dataset_new)
x will already have the values in the threshold range zeroed out, which is what you want. So all you have to do is assign it to a new variable, if you even want a new variable. Otherwise you can just use x as-is.
