输入:一个最小值(value MIN)、最大值(valueMAX)，以及你想要的分段数量(TargetNm)。输出:最合适的等差序列，为了使用方便美观，以1,2,3,5及他们与10的整数次幂(含负整数)的乘积为步长,依次判断并选出与计划分段数量(TargetNm)最为符合和接近的步长，据此形成等差序列。大多数情况下，最终生成的分段个数会在你想得到的个数上下波动，但一定是最适宜的。

Input: a minimum value (value MIN), maximum value (value MAX), and the number of segments you want (TargetNm). Output: The most suitable arithmetic sequence. For ease of use and beauty, take 1, 2, 3, 5 and their product with integer powers of 10 (including negative integers) as potential step(default range:1×10^-8~5×10^8). Judge them in turn and select the step that is closest fitted to the planned segment number (TargetNm) . Accordingly, an arithmetic sequence is formed. In most cases, the number of final generated segments will fluctuate up and down the number you want, but it should be the most appropriate.
