Curve
3 points to clickA smooth curve between two points.
What it looks like
The numbered dots are where you click. Once drawn, you can grab those dots and move them.
How to draw it
Click the start and end, then drag the middle to set how it bends.
When to use it
A curve can be made to fit anything — do not let fitting become the argument.
In SQMATE
What you draw stays
Lines you draw are saved to that symbol's notebook. Open the symbol again and they are still there.
Editable afterwards
Grab the points to move them, and change colour, width and line style. Undo works too.
Shares as drawn
Send the chart as a single link. Whoever opens it sees the same lines.
