I would like to have an XY Chart that has the same functionality as the Waveform Chart, but with x and y inputs instead of just the y. The XY Graph is not efficient to be used inside of a loop, mainly because it redraws the plots each iteration, and I've had a hard time trying to make a buffer that is as efficient as the waveform chart. The Waveform Chart does not allow you to define the x-axis as anything that is not an interval. For example, I might want to plot pressure vs. flow rate. Many customers also request the ability to change the sampling rate during an experiment. this would be much easier to handle with an XY Chart.
It would also be nice to have the buffer size included in a property node.
It would also be nice to have the ability to change the size of the graph palette.
It would also be nice to have the nearest plot coordinates (x and y values), or interpolated values, to mouse movements over the plot area as a "visible item" in the shortcut menu (this should show a dot over the plot's trace)... I've done this with an X Control, but I'd like the ability built into the new XY Chart on a lower level to improve effiecency.
