How to move whole curve?

[hans0504Participant]

Dear DataGraph Team,

Could you please help me about how to deal with the x axis, like the screenshot shows,

1. How can I accurately and conveniently find the values of the x and y of point A, which intersected from the curve and line y= 0.5 ?

2. How can I move the whole curve in the left direction, to the position, which the x value of point A is „0“ ?

PS: the curve type is smooth

Thanks a lot!

Best regards

There isn’t a simple way to compute the exact intersection here.  It is however very easy to shift a plot.  This is done inside the Plot drawing command using the “Plot offset” coordinate.

You can do this somewhat interactively by extracting the x coordinate from the label drawing command (use the gear menu for the Label command).  Then you can use that in the plot offset, since the plot offset can use global variables.

That way you can move it by eye, and the label command will snap to the nearest point on the plot, it just doesn’t snap to an intersection.

Dear David,

Thank you so much for your kindly help!

It works now to shift the plot. : )

Best regards
