I have an area bounded by a data set in the (-) plane as shown below. Is it mathematically possible to represent this area (blue color) in (-) plane?
clear; clc;
data = [1.0000 0.9000 0.8000 0.7000 0.6000 0.5000 0.4000 0.3000 0.2000 0.1000 0 -0.1000 -0.2000 -0.3000 -0.4000 -0.5000 -0.6000 -0.6000 -0.6000 -0.6000 -0.6000 -0.5000 -0.4000 -0.3000 -0.2000 -0.1000 0 0.1000 0.2000 0.3000 0.4000 0.5000 0.6000 0.7000 0.8000 0.9000 1.0000

To have different data (like area) on a different/additional axis, see yyaxis
help yyaxis
yyaxis - Create chart with two y-axes This MATLAB function activates the side of the current axes associated with the left y-axis. Syntax yyaxis left yyaxis right yyaxis(ax,___) Input Arguments ax - Target axes current axes (default) | Axes object Examples openExample('graphics/PlotDataUsingTwoYAxesExample') openExample('graphics/AddAxisLabelsExample') openExample('graphics/PlotMultipleSetsOfDataOnEachSideExample') openExample('graphics/ControlColorsForEachSideExample') openExample('graphics/ControlsIndividualPlotColorsForLeftSideExample') openExample('graphics/YYaxisSpecificAxesExample') See also plot, stem, stairs, bar, hold, cla Introduced in MATLAB in R2016a Documentation for yyaxis doc yyaxis
