Instructions: Redraw each of the three graphs you submitted as poorly designed graphs from the literature.

Approximate the data points from the original graph and enter the data into the SigmaPlot worksheet.

Create a graph in SigmaPlot according to the recommended settings described in the Interactive Lesson.

Export the graph (see page 8) and click on the image icon below to insert the image.

Tips for approximating data from published graphs

For line graphs, use a ruler and pencil to draw lines from a data point on the published graph to the x- and y-axes to determine the x and y coordinates. Repeat this process for additional data points until you have sufficient data points to reconstruct the original line in SigmaPlot.

For bar and pie graphs, simple approximate the bar heights and pie slices for your SigmaPlot data set.

SigmaPlot worksheet

Enter the data points you approximated from the original graphs.

Tip. Use F9 (function key 9) to add column titles.

Tip: Experiment with the Insertion Mode function (see “Edit” on SigmaPlot menu) when entering or editing the data in your worksheet.

Export the graph

Tip: Group all object on the graph before exporting your graph to ensure that all objects are exported.

Edit > Select all

Format > Group

Experiment with various Export settings to see the difference in quality in the exported image.

Tip: For the highest quality for publication, use Export settings as shown in the image below (note that this will result in a relatively large file that can be reduced in size with a photo-editing program). For this assignment, use a lower resolution setting (e.g., 150 dpi, monochrome).

Insert your graph into the blue-bordered box in the document (re-size if needed)

To insert the image into this document:

Click in the image box (page 1).

On Word home menu:

Select Insert

Select Picture

Browse to your image file

OK.

Select the image and adjust its size (if needed) to fit within margins of the first page.

Settings for scanning images

Set the scanner for a resolution of 150 dpi.

If you do not have access to a scanner, scan the image at a local office service center (e.g., Kinkos FedEX, Office Depot, Staples, a copy center, or local library).

Use “black and white” setting for graphs with solid components (e.g., lines, symbols, etc.).

Use “gray scale” setting for graphs with gray areas (e.g., shading, patterns).

Use “color” setting for graphs that have color components.

Save your image as a “jpg” file (no compression).
