Area plot is not exporting high quality figure

I am trying to draw two area graph from timeseries variable stored in workspace. But the quality of the figure I am getting is not so good as that of plot graph. The quality of the output figure is very good if I use plot command instead of area command. Is there any way to get the same high quality figure for the area graph too??

I have tried to export as svg, emf, tif, pdf to use with 'Word'.

subplot(2,1,1)
% plot(P.time, P.data,'linewidth',2)  % gives high quality figure output
area(P.time, P.data,'linewidth',2)    % doesn't give high quality figure output
hold on
area(Pd123.time, Pd123.data,'linewidth',2);



subplot(2,1,2)
plot(I.time, I.data, 'linewidth', 1.3)
hold on
plot(Id123.time, Id123.data, 'linewidth', 1.3);

plot() would be vector graphics. area() uses patches, which are surface graphics, which would be rasterized for everything other than possibly svg() or pdf(). In practice it would probably be rasterized for pdf() as well.

So, theres no way to get good qulity output.

If you have older systems, use the FEX contribution export_fig() .

If you were using R2020a or later, you could use exportgraphics() https://www.mathworks.com/help/matlab/ref/exportgraphics.html

I have used the following code

ax = gcf;
export_fig(ax,'BarChart.svg','ContentType','vector')

and getting the following error.

Undefined function 'export_fig' for input arguments of type 'matlab.ui.Figure'.

Error in plots (line 590)
export_fig(ax,'BarChart.svg','ContentType','vector')

Use the Add-on Explorer to install export_fig

I have tried exprtgraphics from one of my friends pc since my Matlab is 2019a. Figure quality improves but legend overwrite margins.
