Hello,

I have 3 datasets that were obtained at positions 1-10 and have values.

The positions in the table are Strings, i.e. '1', '2', and each dataset contains values for each position.

Now I want to plot the data from all three datasets for each position next to each other in the same (scatter?) plot.

This is what I roughly want it to look like, excuse the crude image. I think I found a picture of what I want it to look like before, but I can't find it anymore.

The dots at each point should be evenly spaced out in the x-axis and there should be enoughenough spacing between the individual points 1-10 in the x-axis.

How can I achieve this? I tried using the reguar scatterplot, but that puts the dots on a line which makes it hard to read:

I pick the datapoints I want to plot from each dataset through an array of strings:

plotPositionDataset1 = [string(1:10)];

plotPositionDataset2 = [string(1:10)];

plotPositionDataset3 = [string(1:10)];

To map the strings I want to plot with the ones in my table I used categorical:

scatterPlotdataX = categorical(Table_Data_1.Position,plotPositionDataset1);

scatterPlotdataY = Table_Data_1.values;

scatter(scatterPlotdataX,scatterPlotdataY,20,"red","o","LineWidth",0.7,"DisplayName","Test1");

Then I repeat the process for all three, which results in the second from figure above.

How can I create a plot that looks like the first figure above? I looked at swarm plots, but that isn't exactly what I want.

See if the swarmchart function (introduced in R2020b) will do what you want.

Thank you for your effort. Not sure if I should mark this as solved.

For now I ended up using the regular scatter plot with 3 different symbols and colours. It is somewhat readable and good for now.

My pleasure!
