+## Transform
+You can move(x&y) or change scale(x&y) of the function on graph!
+
+```java
+formula.applyTransformMove(3f,2.5f);
+formula.applyTransformScale(1.5f,1.5f);
+```
+
+## MultiFormula
+You can also draw multi functions together.

+```java
+public class HeartGraphFormula extends AXGraphMultiFormula {
+
