I've got two sets of data which I want to use on the same graph but not sure how to do it like I want. I can get one set working in Excel by using the scatter graph but I want the two sets on there.
The times are in milliseconds, both sets starting at different times and both received at slightly different times, so nothing matches up. How can I synchronise them on the graph?
I'd like them to both be in sync, yes.
so you want event 1 in set 1 to graph at the same imaginary time point as event 1 set 2? Then just drop the time table and replace with an numeric index. Select that index as the x-axis data for each data set.
Not sure. Maybe yes or no.
So I have say
568,19
1568,19
2568,19.5
3568,20
and
1234,5
2234,5
3234,5
So I want both the temps to be using the same time scale and for the points to be in the correct places. I'm not sure if I'm making sense. I'm sure it's easy enough to do.
Also I can't guarantee the same number of samples from each set, if the signal drops, so want the times to still be correct if one set is missing data.
Since x>0, you could try a log scale.
What would a log scale do? I don't remember them too well from school apart from making a curving increasing line.
I've attached a drawing of what I want. I'm sure its simple.
X and Y are both the same scale on each set, I just want each point on the graph to correspond to the correct x/y value.
Oh, hang on, I think I just figured out your problem. It's not the scale so much as getting both sets of data onto the graph. Correct?
If that's the case, create a table with four columns. Time1, Temp1, Time2, Temp2. Create the scatter plot with Temp1 vs Time1. Then select the graph, right click, and 'select data set' (or something like that, I'm doing this from memory). In the dialogue box create a new data set and set the x to be the Time2 column/boxes, and y to be the matching temp.
I thought the problem was the scale. See ^
That's what I want, yeah. I'll give that a go, thanks.
