Bland and Altman devised a simple, but informative, way of graphing the comparison of two assay methods: First measure multiple samples using both methods. Then plot the difference between the two measurements as a function of the average of the two measurements of each sample (your best estimate of the true value). The resulting graph is called a Bland-Altman plot
