Hello
I am trying to place some text at upper left corner of my Plot so I used the following code but as there is difference between the data so the text placed is sometimes overlaping, as its using the data to determine the location. So can anyone please sugesst the different way to acheive the same.
Here is the code I used:
P_p=plot(Totalpressure_given,Totalpressure_given,'*g');
hold on
P_p2=plot(Totalpressure_given,Totalpressure_obtained,'*r');
X_p=get(P_p,'XData');
Y_p=get(P_p,'YData');
X_p2=get(P_p2,'XData');
Y_p2=get(P_p2,'YData');
imax=find(max(Y_p)==Y_p);
imin=find(min(Y_p)==Y_p);
imax2=find(max(Y_p2)==Y_p2);
imin2=find(min(Y_p2)==Y_p2);
text(X_p(imin(1,1)),Y_p(imax),['Average Difference: ',num2str(Avg_Difference_P)]);
text(X_p2(imin2(1,1)),Y_p2(imax2),['Standard Deviation: ',num2str(SD_P)]);
There is also a way using cell but that I am not able to implement properly.
How I can properly place the text?
Please Guide
Regards

More specifically, where are you trying to locate the text--just out of the way of the data or relative to the data points?
BTW, there's no need for all the get calls, you've already got the data that you plotted in the two arrays. I'd recommend to use shorter variable names for the convenience factor of not having so much steenkin' typing and long lines in the subsequent usage. You can simplify the plotting call somewhat, too...
hL=plot(Tpr_g,Tpr_g,'*g', Tpr_g,Tpr_o,'*r');

Guessing here because I can’t run your code.
Those might solve your problem.

MATLAB lets you control all of the text properties , particularly you will want to look at Extent , Position , Units , HorizontalAlignment , VerticalAlignment ,...
For example:
- If you want your text to stay in a particular location, regardless of the data, then look at the units and Position properties.
- If you want to adjust how the text is aligned relative to the data, look at Extent.
Keep in mind that this is MATLAB: there is no "intelligent" tool that knows exactly where you want your text to be, you have to calculate that text location yourself. And keep an eye on the units!
