vector accuracy comparison graphically

Hello,

I have three data (3*45523 single) as a result of three different methods excited by same frequency. Data matrices consist of complex numbers(vectors).How can I visualize the accuracy(relation) between these three data(or just two)graphically?

Thanks in advance

I would take the mean of the three and then plot the percent difference from the mean. It really depends on the nature of the data. Are all the values of the vectors essentially the same (like the matrix is essentially all ones, with small variation?) If they are mostly the same, then the percentage would not be needed, just the difference from the mean, If there is a nominal value, then instead of the mean, you could look at the difference from the nominal value.
