How to plot the value from multiple rows over one row using different tables?

I'm trying to get the growth (represented in each week W1) of a genotype ploted over the salt accumilation in the soil for the matching group.
Table 1 = PG
Table 2 = acumilation
I'm trying to get the output to be similar to this graph with the salt acumilation being the x axis and the plant growth being the y axis. and the variables being the genotype.
Since there are two different unique salt accumilation methods. I believe making two graphs would be best, one showing the 200mM accumilation and the other showing the 400mM accumilation.
This is the current code I have
for i = PG.Groups('200mM-NaCl-1')
for j = PlantGrowth.Genotype in i
avgrowth = PlantGrowth(PlantGrowth(:,W1))
I'm currently unsure how to get the growth values for each genotype in the 200mM-NaCl-1 group and plot them over the weekly salt accumilation values for the respective group.
I have attached both tables

MartinLuther, this is likely not hard to do, you need to be much more clear. Your tables seem to have little to do with your example figure:
  • I see NO values in the 400-600 range in those tables, yet that's what I see in the figure
  • The legend shows what I guess are genotypes, NONE of those are in your data
  • The W1 etc. seem to be some sort of time series, but who knows?
  • etc.
You need to show exactly how the example data you have provided are turned into a figure.

Hi Martinluther,
As per the description provided you want to plot the growth for a group ‘200mM NaCl-1’ for each ‘Genotype’ against salt accumulation across all the weeks.
Based on this understanding I have plotted the same for two ‘Genotypes’ “WT-2” & “35N8-1-2”. For the same, here is the a sample script you can refer to:
load("acumilation.mat");
load("PG.mat");
groups = PG.Groups;
y1 = PG((groups == "200mM NaCl-1" & PG.Genotype == "WT-2"),:);
y2 = PG((groups == "200mM NaCl-1" & PG.Genotype == "35N8-1-2"),:);
growth1 = y1{1,3:7};
growth2 = y2{1,3:7};
x = acumilation((acumilation.Groups == "200mM NaCl-1"),:);
accum = x{1,2:6};
plot(growth1,accum,growth2,accum);
legend(PG.Genotype{:,1},'Location','southwest');
In the above script the "growth1" holds the data for 1st genotype and "growth2" holds the data for 2nd genotype. And ‘accum’ holds the salt accumulation over weeks. "y1" & "y2" are cell arrays.
Please refer to the following documentation for further details on how to access elements from a cell array:
