Brush Editor — curve graph controls
For stylus input, but not only.
Dynamics controls link a dynamically changing input (like your stylus pressure) to a chosen brush parameter (like size).
Curve graph (here: Pressure—Size)
a Brush Editor tab Dynamics section
Invert (mirrors the curve horizontally)
Preset curve shapes for quick application
Output (Here: Size)
Title (input type) tap to activate/deactivate
Curve editing Drag existing nodes; tap on curve to add a new node. Drag a node over one of its neighbors to remove.
Input (Here: stylus pressure)
Changes to the curve graph are applied to the brush immediately.
Curve graph tap to edit
Note: there is no undo feature here and no reset to defaults. however you can reset the brush to defaults (see page 87).

The dynamic input can be: stylus pressure, velocity and tilt. Velocity can be used with finger-painting as well.
Pressure
Velocity
Tilt
Basic math: Each curve diagram shows the relationship between the input values (like stylus pressure; on horizontal axis, “X”) and output values (like resulting brush size; on vertical “Y” axis). In case of pressure, the most obvious and default is linear relationship (straight line from lower-left to upper-right corner; the harder you press the stylus the more effect you get). But for Velocity-Size you would probably want it reversed (the faster you move the stylus, the thinner the line gets).
The best way to learn how the curves work is to start playing with them.
how hard you press the stylus
the speed of the stylus or your finger
the angle of the stylus
