Automatic positioning of text on the chart

27 views (last 30 days)
Hello, I often rearrange the schedule and I have to correct the text placement position every time. Is it possible to set its position as, for example, the center of the visible graph window?
Now the text flies out of the visible part of the graph when the limits change
x = 0:100;
y = log10(x);
plot(x, y)
t= text(0.5, 0.5, 'y = log_{10}(x)')
s = t.FontSize;
t.FontSize = 24;

Hi, you can get the desired behaviour using annotation (see

Please tell me how I can use normalized coordinates?

When you call annotation() the position units already default to 'normalized', so you do not need to do anything special: just pass on values that are a fraction of the position of the container being annotated.
Note however that a normalized unit of 0.5 on the width would be relative to the whole axes, not to the drawing area. As your axes labels are often on the left, the middle of the drawing area is typically more than halfway to the right. See also the axes InnerPosition property, which might give you information to calculate the drawing area.
