vector of line chart objects returned by plot - problem with modifying markers,...

Dear all,

Here is a snippet of my code:

    plot_array = zeros(5,1);
    x=0:0.1:1000;
    y=x.^3
    for p=1:1:5
        plot_array(p) = loglog(x,y, /*arbitrary markers and legend which I would like to modify after the loop);
        hold on;
    end
    legend_array(2,1).Marker = '+';

The last line produces the error message: "Unable to perform assignment because dot indexing is not supported for variables of this type".

I tried to reproduce the example from the loglog documention. The only difference to my code is that (i) I have an array, -> legend_array(2,1), and (ii) I plot only one pair of vectors, that is why I omitted something like (legend_array(2,1))(1).Marker = '+' .

Thanks for helping me!

I resolved my issue by initializing plot_array as

plot_array = matlab.graphics.chart.primitive.Line.empty(5,0);

Is there may a more elegant way to store line objects?

Try this

x = 0:10;
y = sin(x);
h(1) = plot(x,y,'r');
h(2) = line(x,y+.5);
set(h(2),'marker','.')
