The graph is connected with hold, but the graph is cut off.

It connects two graphs. However, the part connecting the two graphs is broken. I do not know why.

(Figure 1 is an enlarged view of the two graphs in Figure 2.)

please solve. Thank you

Without knowing how the plots were created, all I can assume is that this discontinuity represents a mismatch in the endpoint values of the two data series. You might start by checking to see if the ending/starting values match. If this discontinuity occurs in the middle of one of the series, then there's probably a NaN somewhere.

You can always attach the graphing code and sample data if you want someone to take a look at it.

There was a difference in the endpoint values ​​of the two data. Fortunately, I found it and fixed it. Thank you for your reply.
