How do you create a scatter plot using select columns from app.UITable.Data?

I have a Table where the rows get added and updated. I would like to be able to create a scatter plot of the table. Any thoughts?

Should the plotting be based upon variable (column) number, or should it be based upon column name? Are the column names or number to plot always the same or is there input indicating which ones to select?

Yes, the plotting should be based on variable (column) and the the columns are always the same. I thought I could just convert the two columns of interest to an array and simply due scatter(Column2,Column4), but I can't find a solution.

As an example, the figure below is my table and I would like to create a scatter plot using column1 (%MSO) and Column3 (MEP Amplitude):

Answer 1

scatter(TableName{:,2}, TableName{:,4})

[Walter Roberson]

scatter(TableName{:,1}, TableName{:,3})

This is the error I get:

Error using scatter (line 52)
Must supply X and Y data as first arguments

The problem is that each the table is made up of cells so if I see what's in:

(app.UITable.Data{:,2})

it outputs:

ans =

    '90'


ans =

    '90'


ans =

    '90'


ans =

    '120'


ans =

    '130'


ans =

    '150'


ans =

    '150'


ans =

    '150'


ans =

    '150'


ans =

    '150'


ans =

    '150'


ans =

    '150'


ans =

    '150'

Why are you storing text for your uitable entries? Why are you not storing numeric values?
