All drawing tools can be directly accessed through this object. Although it is the smallest container, it cannot function independently without the object. The default effect of the single coordinate graph is as follows. The horizontal axis of the coordinate system is: (-) which is exactly the same as the interval of the function. The numerical boundary used in this graph is the axis boundary of the coordinate system. Here (-) is used as the default value. This access logic does not have an explicit declaration,,,,, but it does not mean that they do not exist.
The decorator mode is used to hide the details lebanon mobile number of these four objects, which can greatly reduce the input of parameters and reduce the complexity of use. The core framework logic of the drawing tool is sorted out. The single coordinate graph increases the range of the coordinate system. The coordinate axis has two axes, and the size of the axis and the axis are adjusted separately. The range of the adjusted coordinate axis and is inconsistent.This method can be used to adjust the viewing angle of the graph. Logic combing of the core framework of the drawing tool Logic combing of the core framework of the drawing tool Comparison shows that the two curves are exactly the same in terms of numerical value, but the size of the coordinate system is different, so the observable visual is different.
. Single coordinate system superimposed multiple graphs As shown in the code, if only the default multiple superimposed graphs are still applicable, they can only share the same coordinate system. Logic combing of the core framework of the drawing tool Logic combing of the core framework of the drawing tool 5. Multiple coordinate system superimposed multiple graphs When superimposing multiple coordinate axis images, it must be explicitly declared, otherwise it cannot be implemented. No explicit declaration is required because the system will automatically declare each execution when the code is executed. No explicit declaration is required because it is a one-to-one correspondence with and the system will automatically declare when it is an aggregation relationship declaration.
