4 Microsoft Office Visio (My research in UW, 2010) Microsoft Office Word (My modal test lab report in 2002) fillet grip gage section Dogbone specimen Microsoft Office Powerpoint (Lecture Slide, ME354 W2011) Don’t use Microsoft Windows Paint! Improve Your Schematics

5 5 1 1.Inside major tike mark type 2.Must have axis labels and units 3.Keep decimal places consistent 4.Change axis color form grey to black 5.Remove horizontal grid line 2 2 3 4 6.No chart area border 7.Need plot area border 8.Move the legend inside the plot area 9.No markers 6 7 8 9 Improve Your Figures by Microsoft Excel Excel Default Figure

6 A36 Steel 6061 T-6 Aluminum Ultimate Strength: Steel > Al Modulus of Toughness: Steel > Al Modulus of Elasticity: Steel > Al Yielding Strength: Steel ~ Al What are you going to tell your readers? Improve Your Figures by Microsoft Excel (cont’) Failure Strain Ultimate Strength

7 2. decimal place:1 Font style: Times New Roman Font style: Symbol A36 Steel 6061 T-6 Aluminum PMMA Polycarbonate 1. Greek alphabet 3. Inside tick mark type 2. Decimal place 3. Inside tick mark type 1. Greek alphabet: “Times New Roman” to “Symbol” No horizontal grid lines. (You may keep both horizontal and vertical grid lines or remove both of them, but don’t keep either one) Remember axis labels and units. (physical parameter, Greek alphabet, unit. eg: Stress  (MPa) ) If you don’t have color printer, use black color, gray color and different line styles to distinguish different data sets. Either “legend” or “text box in the plot” will suffice to help distinguish different data sets. 4. Change to black axis (default is gray color) 4. Axis color: solid and black Improve Your Figures by Microsoft Excel (cont’)

8 Looks good, but could be better. Distinguished by types of line style and types of data-point symbol– either one of them would suffice. Textboxes by the line might be better than legend. Improve Your Figures by Microsoft Excel (cont’)

9 Different data sets are distinguished by types of data-point symbol. Lines are only for showing the trend of the data. Different data sets are distinguished by types of line style. Types of data-point symbol are only for showing numbers of data point. Improve Your Figures by Microsoft Excel (cont’)

10 1.10 6 M, 10 -6  2.Decimal places inconsistent 3.Unit, Legend and Textbox 4.Different line styles to distinguish different data sets Improve Your Figures by M ATLAB M ATLAB Default Figure – much better than Word

Avoid “ Calibri ” and “italic”. Use “italic” only when you emphasize something, refer to a book name or show writing style. Italic may help Greek alphabets look better. Keep font size and font style consistent in your report. Don’t forget the units. Keep decimal place consistent and decimal place more than three might be meaningless No unit Avoid two rows in a unit This table has Times New Roman, Calibri and italic, three font styles. Only three full-width lines; no vertical lines Table E.6. Stress and Strain at Strain Gage 2 for C-Channel.
