Paste in X, Y values:

Paste in the X and Y values here. Each X value must be a ligand concentration or time point and it should be followed by the corresponding experimental measurement, Y, with an intervening space or text separator. Usually there would be one X and Y value per line (e.g. if pasting from a spreadsheet) although the X and Y pairs can be entered in one line, if so desired. Duplicate measurements can be entered all together in the same manner as the corresponding pairs of X and Y values e.g. one X, Y pair per line. Data can be entered as ordinary decimal numbers, integers, exponentials ('E' or 'e' notation) or a mixture of these formats. Non-numerical text should not matter since the program will try to remove it. If the plot does not appear or the curve does not fit well please check that the data are entered correctly. Note that the fitting relies on the measurements at the lowest and highest values of X providing reasonable estimates of the Y-intercept and asymptote, respectively!
