Question about a graph

bradyj7

Hello,

I have velocity and acceleration data record for a car every second.

I would like to produce a plot like this

For the frequency axis, would you count up the number of observations for each speed and acceleration pair and then divide by the total number of observations?

Thanks

I think so. You can use the total number of observations as well, if you don't care about the scaling of the axis.

You could consider removing all (0,0)-values.

Good idea to leave out the (0,0) information (unless resting time is important to know about). Excel will do the scaling of the graph for you so it wouldn't matter whether or not you divided by total number of observations.
