MFC to connect to the database, using teechar control t draw two curves, the x axis coordinates of time, two different curve of x axis interval (there may be a coincidence), hope curve according to the time to draw, rather than according to the drawing points order, could you tell me how to write code?



As shown in figure, the red curve x range should be in the 2017-05-18 15:29:03:056 to the 2017-05-18 20:53:35: $981, but far more than in the picture, between the blue curve x range for the figure on the 2017-05-18 15:29:03:056 to the 2017-05-21 16:29:44: $970, could you tell me how to make two curve can display the corresponding x range, rather than according to the points to draw,
thank you

Time not drawing line into position, or time fill blank 0 put two curve into the same time
