很多时候人们不会注意到这一点，因为他们认为“我把不同明暗的绿色绘制了图块，所以这是一个草地图块，我可以把它铺满任何想铺的地方。 我该继续画下一个图块了。”
A lot of the time they don't really notice it because they simply think "I have random green dots in a tile, so this is a grass tile, and I can just throw it all over the place...
而如果绘制图像的第一个数据点起始数据不是100%，如果我们把后面同步变化的点拖动到一起会怎么样？

但是第二个图有一些没有连起来的点，它不是一条线，这是加上是绘制了，抱歉，每个点都是红圈圈。
But figure two has not connected the dots, not drawn a line, it's actually planted each, or plotted, excuse me, each point as a red circle.
所以，空中每一点细微的光亮都代表宇宙史上的不同时点，这也是天文学家能够绘制出宇宙进化图的原因。

LRO太空飞行器在仅31英里的高度绕月球飞行，设计该飞行器的目的是绘制空前详细的月球表面地图，以帮助确定未来载人飞行任务可能的着陆点。
Orbiting the moon at an altitude of just 31 miles, the LRO spacecraft is designed to map the lunar surface in unprecedented detail to help identify possible landing sites for future manned missions.
所以，空中每一点细微的光亮都代表宇宙史上的不同时点，这也是天文学家能够绘制出宇宙进化图的原因。
So all those tiny points of light represent different points of time in the history of the Universe and that's how astronomers can build a picture of how the Universe has evolved.
为了补偿这一点，我们添加了支持，以允许父容器定期地(比如每隔0.1秒)重新绘制它自己。
To compensate for this we added support to allow the parent container to periodically (say every 0.1 second) repaint itself.
在这些情况中，我们在两点间绘制了一条直线。
In these cases we have plotted a straight line from one plot to the next.
例如，给出一个集合{10,20,30,40}，您立刻就可以知道要绘制4个点，因为集合中包含4个元素。
For example, given a set {10, 20, 30, 40}, you immediately know that you want to plot four points because the set contains four elements.
