Hi, I have groups of mice, with tumours. Each group gets a specific treatment and tumour growth is measured daily. At the end of the experiment I have data for 3-4 groups, each group consisting of 4-5 mice, how do I create a graph of the data with one line for each group using the average daily measurements for the groups as the points on the lines?

here is part of the table:

where there are four members to each treatment group (with their order changing randomly each day) and a set of measurements for each day (d20, d21, d22 etc)

I need to plot the line for the averages (with error bars) like you can do in prism (my supervisor wants me to use jmp)

thanks for the help
