What type of model should we create for the Weetabix production process?
Friday, 04 September 2009

The Scatter Plot block is a very useful tool, but defining the x, y inputs is "not intutitive" yet. It will be improved, but this note is to help users get started in the mean time.

The ScatterPlotProps screenshot shows the properties for the selected scatter plot block.  Selecting "DataSeries" opens a dialog for as shown in the other screen shot. The series are selected as "#0" and "#1" which are the first and second columns of the input data, in this case passing in from the Column Join Block. Multiple series can be added in this way where the series are indexed as {0,1,2,3,4, ...}. So if there are three coumns in the  input data with column one (#0) containing the x-values and columns 2 (#1) and 3 (#2) containing two y-series, we would add one row with #0,#1 and the second row with #0,#2 values.
