Can we see something of the results ?

Screenshot of the Windows Calculator Graphing app showing the expression 1.48455 sin((x + 40) - 2(pi/180)) + 866.6255 in the input panel, with the plotted graph a nearly flat horizontal line on a grid, axis labels 1400, 50, 100, 150, 200, 250.
This is a fit that I did today. And it fit the data that I measure. it is off at little as you do down. and I think it is because I did not iterate it. I think to iterated it , I would have to solute for A B and w again . I just do not know when to stop.

You should adjust the vertical scale on your graph. What you show here looks like nothing more than a horizontal line, ##y \approx 100##.

I have been trying... but the graphing calculator does not let me... it is very frustrating, I am only using it because it comes with my computer .

Try desmos instead.

It looks like you are using the Windows Calculator to do the graphs.
Click the icon circled below to open the Graph Options dialog.
Windows Calculator Graphing screenshot showing a blue wave curve on x and y axes, with the y-axis ranging from -10 to 10 and the x-axis from -10 to 10, and a red circle around the graph options icon.


On the Graph Options dialog, you can change the scale on the x-axis or the y-axis, change the units (radians, degrees, or grads), or change the line thickness.
Windows Calculator Graph Options dialog with Window settings X-Min -12.833333, X-Max 12.833333, Y-Min -13.577726 and Y-Max 13.577726 circled in red; Units set to Radians.

You'll get a more useful graph by changing the limits on the y-axis to better show the oscillation.
