I need to plot one line on a chart, not two, and I need it to start with my
data a 0 minutes and then go up at 30 second increments. For example, my
temperature at 0 is 37.9, then my data at 30 seconds is 71.2. So how do I
get my chart to show the values at 0 and 30 seconds? I was able to get it to
show those temperatures, but it plotted them starting at 1 minute, not 0.
