How can I extact data for each plot that was used to plot these curves?? 2 Answers Sorted by: 5 The legend text is associated to the line, rather than to a legend object, so: ax_children = get (gca, 'children'); Outputs a line array of the lines I was plotting: ax_children = 2x1 Line array: Line (cos (x)) Line (sin (x)) And then: leg_strings = get (ax_children, 'displayname'); Outputs a cell array: Starting with a 2D matrix I was able to plot it with the first column as the X axis and generate individual sub plots of the remanining columns. One can then browse the figure data in Python and locate the data. Does aliquot matter for final concentration?
