Graph User Manual
Least Squares takes 2D Points and plots them as a 2D scatter plot and also plots a linear regression of those 2D points. Here are a few things to note about this task:
- Touching a data point shows its values and touching the line segment shows the interpolated value of the regression. If you select the Labels representation then you can see the sequence number of each data point.

Data Importing and Exporting Formats
- The Table Editor atomic cell type is a 2D Point, that is two scalars interpreted as the x-value and then y-value. The component cell type is a scalar representing x-values for the first column and y-values for the second column. The column, row and block-select import format is a list of 2D Points separated by a delimiter for atomic cells and scalars for component cells.
- The Edit Data format is a list of pair of numbers (2D points) separated by a blank.
- The Fetch Data format is a list of pair of numbers (2D points) separated by a blank or an XML structure.
