14.1 Direct Worksheet to Matrix Conversion


Spreadsheet users will be familiar with the following type of data arrangement in which you have either:

In the Origin matrix, columns are mapped to linearly-spaced X values; rows are mapped to linearly-spaced Y values. If your worksheet contains linearly-spaced X or Y coordinate values arranged in a fashion similar to the above figure, and you would like to move the data into an Origin matrix, you can do a direct worksheet to matrix conversion of your data (no gridding is performed), extract the Z values and write them to the matrix according to one of seven configurations.

To perform a direct worksheet to matrix conversion of your data:

  1. Open the w2m dialog by selecting Worksheet : Convert to Matrix : Direct from the menu.
  2. Specify the Input Worksheet data, as needed, then specify how you organize the data from Data Format drop-down list under the Conversion Options list, for different data format, choosing different conversion options:

Data Format

The format of the source data:

  • X across columns
The X values are across columns.
  • Y across columns
The Y values are across columns.
  • No X and Y
There are no X or Y values in the worksheet. Column and row indices should be used for X and Y coordinates, respectively.
X Values in

Location of X values. Available when Data Format = X across columns.

  • None
There are no X values in the worksheet. Column indices are used as X values.
  • First Data Row
First data row supplies the X values.
  • Column Label
Column label row supplies the X values.
Y Values in

Location of Y values. Available when Data Format = Y across columns.

  • None
There are no Y values in the worksheet. Column indices are used as Y values.
  • First Data Row
The data row supplies Y values.
  • Column Label
Column label row supplies the Y values.
Y Value in First Column

Check to use the first column values as matrix Y value.

X Value in First Column

Check to use the first column values as matrix X value.

Even Spacing Tolerance

Tolerance to check even spacing.

Use Linear Fit Estimate for Coordinates

Check to use Linear Fit Estimate for Coordinates

Trim Missing

Determine whether to trim the missing rows or columns.

Notes: Selecting the Trim Missing box will drop the entire row or column if it contains missing values. X, Y coordinates in Origin Matrix should be even spacing, Even Spacing Tolerance is used to set the tolerance to check even spacing. There can be no rows above the data to convert and no columns to the left of the data to convert.

Output

Specify three columns for the output XYZ range. X, Y and Z data can be output to different sheets and books.
