How To Create 2D Function Graphs & Animations?
This example creates a graph including graphs of following five functions:
Function 1 y=(x-2)^2 -0.5<=x<2 In the form of y=f(x), Cartesian coordinate system
Function 2 x=2u-2, y=3u-6 2<=u<=4 In the form of parametric, x=f(u), y=f(u)
Function 3 y=6 6<=x<=10 In the form of y=f(x), Cartesian coordinate system
Function 4 x=0, y=0 It's a hollow point
Function 5 r=t*a 0<=a<=2pi, 0<=t<=2 It's an animation, polar coordinate system
Following these steps to create function graphs.
Step 1: Create A New 2D Document
If graphs created before are 2.5D or 3D, click  button first to create a new 2D document.
Step 2: Graph Function 1
Click  button to open 2D Function Graph Properties dialog box. In the dialog box, input (x-2)^2 in y(x) field, input -0.5 in Min x field, input 2 in Max x field, input 100 in Steps x field.
Use Properties tab to set the color of current curve to red, click OK button to create the first graph.
Step 3: Add the Graph Of Function 2
Click button to open 2D Function Graph Properties dialog box. The second function is in the form of parametric, so we should select "x=f1(u),y=f2(u)" item in Form combo box. Input 2u-2 in x(u) field, input 3u-6 in y(u) field, input 2 in Min u field, input 4 in Max u field, input 100 in Steps u field.
Use Properties tab to set the color of current curve to kelly, click OK button to add the second graph.
