There are no save buttons and load buttons in the buttons below, are there? Are you sure it is a historical curve? Can you cut a photo? Is my version different?
Because the equipment runs intermittently, for example, every morning from 8: 00 to 16: 00, I want to save the daily curve as an independent curve table, so I added a "save button".
When viewing, just click the "Load button" to bring up the previously saved record curve of the day.
If you do this, it will be convenient and intuitive.
The historical curve in kingview master control can't be saved and loaded by sections, but it can be queried by date and time.
If the requirements are not very high, the program will run all the time and the data will be recorded continuously. If necessary, just check by time.
If you want to achieve this effect, you may not be able to use the Kingview control.
Xy curves can be saved and loaded, but the number of points is limited. I'm afraid it won't come true after such a long time. I'm also interested in this question. Please tell me if you have a good idea.
