如何用属性节点改变waveform chart 的dt间隔？

[师文江]

假设收到一组数组，而不是波形组，没有dt定义；不在chart外部改变dt，让chart 直接收数组而不是波形，在收到数组的同时，改变dt，怎么做？

why  don't you set dt outside chart?

[师文江]

Because the chart geting oo many  data is too slow at one time. So I transmit the arry not the waveform to it, but the 'dt' of data can't  be set.
