If you want to plot Range on the x axis and angle of projection on the y axis, first you have to find an equation that relates them.

yes i mean total range, can anyone help me out? so basically im looking foir an equation for total range of a projectile with drag

i used calculus to derive the equations knowing gravity and initial velocity and angle.

for drag:

I have calculated the horizontal and vertical distances but is there a way where i can combine these two and use theta in the equation to insert the projectile angle?

or how can i find the angle launched from a vertical vs horizontal displacement graph?

Take the lowest set of data points you can see, eg 0.05m x, 0.07y. Draw a triangle, find the angle with trigonometry. The closer your data points are to zero, the closer they will represent the direction of motion before drag and gravity effected the linearity of the motion as much.

do i need to know the object mass and surface area (to work out Cd) to find it?

Set the new problem up just like you set up your old problems. You started by drawing a free body diagram to find the acceleration in the horizontal and vertical axises, do the same here.
