I need your help.
I am trying to plot a scale on my graph,I did it with the help of my last question
now to plot the value on my horizontal line on the sclae(left top , ? cm/s) I need to have the length between each plot(interval). how many mm or cm is between data on point 0km and point 5km(interval between ticks).I don't know how to find this length!
Then I probably need to find the max of each data and divide it to this lenght. I suppose this will give me the answer for ?m/s
