Waveform charts plotting

[Veena]

I have a data acquisition VI, which acquires two sets of data as x and y values.I have problem plotting them in a waveform chart.I tried bundling them and wiring to the chart, but instead of one plot of x vs y as the data is being acquired, i get to view 2 sets of plots. How to overcome this, so as to plot my x and y values as they are being acquired in a waveform chart.Will someone help.

Hi veena:
See this example VI. It might help you. Also see XY chart examples in LabVIEW.

If the X values are evenly spaced, then you can encode them as X0 and
dX, wire these into a cluster with the Y array, and send that to the chart.

If the values are not evenly spaced, one option is to look at the XY
chart example in examples/general/graph/charts. The example uses a
subVI to collect and limit the number of points, the data is then drawn
using an XY graph.

Hi..my problem is getting to plot the x vs y values as they are being acquired (like a real time plot),and x values are not evenly placed.
Note:Iam working under LabVIEW version 6.0
