1. Select the rounded rectangle tool to draw two identical rounded rectangles with an included angle of 90 degrees, and fill the two rounded rectangles with red.

2. Continue to draw parallel lines with rounded rectangles, so that these rounded rectangles are vertically aligned.

Continue to draw an upward curve with the pen tool, draw angles and arrows.

3. Set the foreground color to blue, and fill the upward arrow with blue to make a blue and red figure.

4. Then, we draw a graph, choose the rounded rectangle to draw two identical rectangles, which are the horizontal axis and the vertical axis on the left side of the graph.

5. Continue to draw many rectangles with rounded corners in the vertical direction so that they are aligned in the horizontal direction. Then intercept it with two triangles, one big and one small, so that the outline of the whole figure can be presented.

6. Continue to draw a sharp arrow with pen and ink to make it consistent with the green curve. Fill this arrow with yellow, and the curve stick figure is completed.
