Hi, in order to finish my case study i need to use the toolbox in the climate data store to plot a one line basic time-series graph of the levels of chloropyll-a in the arctic ocean, but i have gone through every tutorial and how-to-guide and still I can't make it to plot a graph. I have tried with a monthly range of 1 year.

Can anyone with help me with this?
