You want to use different shapes and line types in your graph. For BGR, we pass a tuple. Re: scale a ellipse according to mouse. 1 year ago. Code explanation: The x1 attribute defines the start of the line on the x-axis. An ellipse is the locus of all those points in a plane such that the sum of their distances from two fixed points in the plane, is constant.
The difference is that an ellipse has an x and a y radius that differs from each other, while a circle has equal x and y radius.
thickness: It is the thickness of the shape border line in px. If it contains two elements the first will be used for the label and the second for the description. Appearance # In Appearance property Plot confidence ellipses. THICKNESS= n
The fixed points are known as the foci (singular focus), which are surrounded by the curve.
