This seems like it should be very simple, but it doesn't work. I am plotting two lines in a figure, and want to save the figure as an image. However, the handle h is a vector and saveas doesn't like it. I can't find any help with this in the documentation. What am I missing?

h = plot(price,supply,price,demand)
saveas(h,'myplot','png')

This is the real example. It is a simple supply and demand plot.

Your code is just saving the current axes, you want;

hfig = figure;
hplot = plot(price,supply,price,demand)
saveas(hfig,'myplot','png')

Works! Thanks.

so the handles returned by plot are for each plot in the figure. hfig=figure; gives the handle to the whole figure.

Thats what I need to know.

To be precise, the handles returned by plot are handles each of the line objects that make up the plot.

h = plot(price, supply, price, demand);  %handles to 2 line objects
ha = get(h(1),'parent');                    %handle to axes object
hf = get(ha,'parent');                   %handle to figure object
