plot each cast for each year using findgroups and splitapply

Hello,
I have a dataset with temperature, depth, castID and year. For each year, there are multiple casts, and the castID is associated with multiple temperature and depth readings. I would like to group the data by year, then plot each individual cast in that year using a specific color so that each cast associated with e.g., yr 2010 is green.
group_yr=findgroups(CASTYEAR);
figure;hold on;
Y=splitapply(@plot,TEMP_DEGC,DEPTH_M,group);
The issue is that matlab assumes all the casts in 2010 is a continuous dataset and so the plot lines are continuous as well, rather than seperate for each castID. I think I should also apply: group_ID=findgroups(CASTID);
But Im not sure how to plot according to group_ID and group_yr, and when I use:
Y=splitapply(@plot,TEMP_DEGC,DEPTH_M,group_ID(group_yr==1);
it does not work.

You can use multiple variables to create groups using findgroups()
groups = findgroups(CASTYEAR, CASTID);

You can still use the line
Y=splitapply(@plot,TEMP_DEGC,DEPTH_M,group);
