Above, I placed on MFC interface, a High - Speed charting drawing controls, used to display serial upload data, dynamic update 1 seconds 5 points, this drawing control can display 500 points at a time, now the abscissa setting is displayed automatically, when the effect of data update is the waveform in the move to the left, and the abscissa is every 100 points according to coordinate values at a time, I hope the effect of every once in a while (such as 10 seconds) shows the horizontal coordinate values, in the process of data updating abscissa in 10 seconds, 20 seconds, 30 seconds... Place to display, could you tell me how to achieve this?

CodePudding user response:

And display is also 10, 30, or directly display the current time, accurate to seconds

CodePudding user response:

Rewrite the abscissa curve? Or on the label and a timer display?
