And the OP then talks about text() needing coordinates to locate the text within the figure, which is not something that text() ever did. We conclude that the OP was using the wrong terminology.

在 MATLAB Online 中打开

FigH = figure;
AxesH = axes('Parent', FigH, ...
  'Units', 'normalized', ...
  'Position', [0, 0, 1, 1], ...
  'Visible', 'off', ...
  'XLim', [0, 1], ...
  'YLim', [0, 1], ...
  'NextPlot', 'add');
TextH = text(0,1, 'Top left', ...
  'HorizontalAlignment', 'left', ...
  'VerticalAlignment', 'top');

Now you can inspect the properties with "get(TextH)" or "set(TextH)" for further adjustments.

Sometimes a UICONTROL('Style', 'text') is easier, because it does not need the invisible full-figure AXES object.

I find the documentation on 'text' to be nearly useless in this matter. The following places text at the top left of the graph.

    ylimits = ylim;
    ymax = ylimits(2);
    vert_spacing = ymax/47;  %may have to experiment with this #
    text(10, ymax-vert_spacing*1, 'Line 1');
    text(10, ymax-vert_spacing*2, 'Line 2');
    ...

What do you mean "top left"? Top left of the figure? Top left of the screen? Top left of the axes?

Have you looked at the function text?

The text needs a pair of coordinates to locate it in the figure. In the case of the legend there is an option to place it in different positions through the property "location". Is possible use the property "location" with text? Thanks
