Waveform Chart Update With Relative Time

[Gus67]

Hey,

I have a question about how a waveform chart updates.  I am running a test in the pictures attached it is only for 4 minutes and I read in a data value every 90 seconds.  I was wondering why the waveform chart doesn't look like chart 2 (photoshop what I want) instead it looks like chart 1. 

I pass to the waveform chart a double every 90 seconds or so. How can I make the chart behave like picture 2? Where it connects the data points with the time each data value is sent to the chart.

Actually if you look carefully at chart 1 it appears that it is connecting the dots. But the time scale is messed up. Can you post some example code?
