scatter绘制多条曲线 MATLAB

英语翻译
The graphs should be x-y scatter (no lines).Only the trendlines should be linear or quadratic functions.
这句话说 图应该是散点图（没有直线的）,那为什么后面说又要有趋势线,可是前面说没有直线的?

When the three falls,the monkeys scatter.
是一条谚语

The scattering program requires the Scatter,ScatterAnalysis,and ScatterApp classes.The ScatterApp class in Listing 5.6 organizes the startup process and creates the visualizations.As usual,it extends AbstractSimul ati on by overriding the doStep method.However,in this case a single step is not a time step.A step calculates a trajectory and scattering angle for the given impact parameter.After a trajectory is calculated,the impact parameter is incremented and the panel is repainted.If necessary,you can eliminate this visualization to increase the computational speed.If the new impact parameter exceeds the beam radius bmax,the animation is stopped and the accumulated data is analyzed.Note that the cal cul ateTrajectory method returns true if the calculation succeeded and that an error message is printed if the calculation fails.Including a failsafe mechanism to stop a computation is good programming practice.

ARM scatter文件的length如何计算?
scatte文件如下：
LOAD 0x30008000
{
RAM_EXEC +0
{
startup.o (init,+FIRST)
* (+RO)
}
STACK +0x100000 UNINIT
{
stack.o (+ZI)
}
RAM +0
{
* (+RW,+ZI)
}
HEAP +0 UNINIT
{
heap.o (+ZI)
}
EXCEPTION_EXEC 0 OVERLAY ; exception region
{
exception.o (+RO)
}
}
那么在ldr r2,=|Image$$EXCEPTION_EXEC$$Length|中,length是怎么算出来的?R2?

各位高手帮我翻译下这段英语吧!
The Scatter class shown in Listing 5.7 calculates the trajectories by expressing the
equation of motion as a rate equation. The most important method is calcul ateTrajectory, which calculates a trajectory by stepping the differential equation solver and adding the resulting data to a trail to display the path. Because the beam source is far away, we stop the calculation when the distance of the scattered particle from the target exceeds the initial distance. Note the use of the ternary ?: operator. This very efficient and compact operator uses three expressions. The first expression evaluates to a boolean. If this expression is true, then the statement after the ? is executed. If this expression is false, then the statement after the : is executed. However, because some potentials may trap particles for long periods of time, we also stop the calculation after a predetermined number of time steps.
