MATLAB: A function that draws a plot and use an input for the filename of the plot

MATLABplot

To continue,
In my Livescript called test.mlx, I have variables
days
temperatures
I now want to write a function m file that outputs a plot with specification as
plot(days, temperatures)
legend('temperatures')
title('Figure figurenumber. Temperatures')
saveas(gca,'c:\Figure_figurenumber')
Then, what I did is to write a function m file called plot1.m
function plot_test(series1, series2, figurenumber)
plot(series1, series2)
legend('series2')
titlename=['Figure',num2str(figurenumber)]
title(titlename)
end
Then how should one understand the
saveas
part?

  • See below for sample code:
    close all
    % Initialize some data
    temperatures = rand(1,30)*35;
    plot_test(temperatures, 1);
    function plot_test(temperatures, figurenumber)
    % Plot data
    figure()
    plot(temperatures);
    legend('temperatures');
    % Create title
    titlename = ['Figure ' num2str(figurenumber)];
    title(titlename);
    % Create save location
    % Make sure to specify the format of the image you want to save at the end.
    % pwd will save your file to the current working directory. If you have a specific save location
    % in mind, specify the absolute file path.
    fileName = ['Figure_' num2str(figurenumber) '.jpg'];
    saveas(gcf, fullfile(pwd, fileName))
    end
