I can get the temprature ,humidity and co2 data from sensors.Now l want to show them in one xy graph, and the x-axis shows the absolut time. I already set different y-axis, and tried many ways, but still can't get three curves.

The numer of x points needs to be the same as the number of y points.
Each plot needs to be an array, currently you only have a single plot with 3 points.
Your property nodes are not necessary.
What determines the loop rate?
Please attach your VI instead of a picture. We cannot tell how the express Vi is configured. (e.g. is it set to retain data? You would probably run out of memory pretty quickly.)
If the timing (=loop rate) is regular, you might be better off with a chart instead.

So far you did not answer any of my question in my earlier post. Why not?
