EXERCISE 1

Open the Workshop_samples folder and open redpine5.xls

ENTERING DATA
There are several ways to get data into a SigmaPlot worksheet
  • Enter directly into Sigmaplot worksheet or open an Excel worksheet within SigmaPlot and enter data.
  • Copy/Paste from other sources (Excel)
  • Import from other sources (Excel)
  • You may need to format some data before bringing into SigmaPlot
    • Cells with Formulas - copy | paste special as values in Excel, then copy | paste the values
    • Set precision format as numeric with decimal precision set in Excel before copy | paste to SigmaPlot.
    • Dates (some date formats will not be recognized correctly) In SigmaPlot make the datasheet active
    Copy/Paste from other programs
    • Copy data from the Excel worksheet
      Ctrl-* is a good way to select a block of data in Excel. This Selects the current region around the active cell (the current region is a data area enclosed by blank rows and blank columns).
    • Paste data to data worksheet in Sigma Plot
      While you can open an Excel spreadsheet directly in SigmaPlot, there are advantages to just pasting in the data you want to graph
      • The Excel workbook is a backup file of the data should anything go wrong in SigmaPlot
      • You only have the data on the SigmaPlot worksheet that you need for the current graph, many times it's best to have each data sheet be a subset of the more complex data set
    • You must promote the column headings in row 1 to be titles. Select Row 1 in the worksheet, then go to Format | Column and Row Titles | Promote or hit F9

CREATING A GRAPH

    Using the Graph Wizard
    • Select Data 1 worksheet and launch the Graph Wizard. To launch the Graph Wizard use one of these options:
      • 2D and 3D Graph Toolbar OR
      • Graph Wizard icon OR
      • Graph | Create Graph OR
      • F3
    • Graph Types- Scatter Plot - next
    • Graph Styles - Simple Scatter - next
    • Data Format - XY Pair - next
    • You may get a warning message: You have selected more than 16,000 data columns. Would you rather make a smaller selection? - YES
    • Highlight Data for X: select SPA from pull down menu
