System Information
Operating system: win10
Graphics card: 1050ti

Blender Version
Broken: (3.0 beta)
Worked: (2.79)

Short description of error
Whole curve gets selected if Circle select (C key) is clicked on curve itself and not a keyframe point.
In 2.79 no matter where you've clicked with circle selection: if keyframe isn't inside boundary - nothing will be selected.

Exact steps for others to reproduce the error

open file, look at the Graph Editor
press C to activate Circle selection

click between keyframes -> all keys are selected

Thanks for the report, but this is a new feature implemented in 2246d456aa, discussed and approved in #84901 (Curves Interactions in the Graph Editor).

@mano-wii Thanks for merging the duplicate tasks.

Maybe the bug description is not detailed enough. Let me try again:

There are 3 types of Curve Selections: lasso, box, and circle. Their behaviour changed in 3.0. Box and Lasso are good, Circle is broken.

Current behaviour

Box selection - it has two types of selection:
- When the user selects curve points with the box area, he/she selects just the ones inside that box area. One can select different sets of curve points from multiple curves this way
- If the user selects the curve itself (just the line) without any curve points inside the box area the whole curve with all its curve points will be selected
Lasso selection - it has two types of selection similar to the Box selection:
- When the user selects curve points with the lasso area, he/she selects just the ones inside that lasso area. One can select different sets of curve points from multiple curves this way
- If the user selects the curve itself (just the line) without any curve points inside the lasso area the whole curve with all its curve points will be selected
Circle selection - it is the bugged selection where we have the problem. It's not consistent with the other two selections - Lasso and Box. Instead of having similar two types of selection, it has just one. It either selects all the curve points of the clicked curve. Or randomly switches from selected curve points to all the curve points if you drag your circle selection to the curve line. This behaviour makes the Circle Selection suitable for the selection of only the whole curve which makes no sense for an animator. Use case: cleanup of motion capture animation where animator selects multiple curve points with Circle Selection and interacts with them. Now it's not possible to do.

Expected behaviour of Circle Selection

There should be two selection types as in the other two selections (box, lasso):

When the user selects curve points with the Circle Selection, he/she selects just the ones inside that circle area. One can select different sets of curve points from multiple curves this way. It's activated if there is any curve point in the radius of the circle area on click. When dragging the mouse only curve points should be selected within the circle selection radius.
When the user selects just the line of the curve without any curve points inside the circle selection radius the whole curve with all its curve points should be selected. It's activated only if there are no curve points in the radius of selection on click.

Thanks.

The behavior described for circle selection only happens if you start the selection from the outside (with no point inside) and move towards the curve.
In this case it seems more difficult for a point to be selected before the line. So the curve is more likely to be selected first.
It's a little unpredictable but it doesn't seem like a bug in my opinion.

The #animation_rigging team can reopen the discussion if it seems necessary.

@mano-wii

It works in cases like the one you showed. But here is a more real-life example which shows the problem:

And that's just one curve.

In the example Germano posted, it still seems like a bug since one moment it picks the entire curve but then if you drag down, it picks only keys, not the curve.

In the second example, it started to pick just the key, then switches to select the entire curve once moved.

It looks like a bug in that it isn't consistent in what it should be selecting.

I agree that new behavior feels inconsistent, because one awkward mouse drag and you ruin whole selection already made. Also don't understand what is useful in selecting full fcurve with circle tool, as it can be done by simple double clicking on fcurve's name.
