Open adobe illustrator Programme is available in listed computer rooms (see MyCourses) Open coastal_pop.eps

Remove clipping mask, grouping, Matlab, excel and other programmes produce unnecessary masks and grouping to vector files. It is advisable to remove those before starting to work with the figure. Do as follows: Do following commands from menu bar Select – All Object – Ungroup Object – Clipping mask – release Object – Compound path – release

Delete masks After you have released the masks, you can delete them by selecting the white areas and pressing delete (the A4 page remaining is the art board and you cannot delete that)

Move objects If you want to move multiple objects, you might first want to group them together Select the objects to group and select Object – Group (Ctrl + G) If you’re left with unnecessary things like the white background box you can just delete them

Align and distribute tools Sometimes you want to arrange objects differently than in your original Matlab plot Align and distribute tools are useful for that You can find them under Window – Align For example, in Matlab we distributed the bars based on year, but if you change your mind and want to distribute them equally instead, it is very easy in Illustrator

Distribute example Experiment with align tools as well First group each pair of bars and their year label together (Ctrl + G) Select all bars and year labels Select Horizontal Distribute Space from Align toolbar Experiment with align tools as well For instance, you can try to vertically align the center points of the y-axis label and the legend

Removing unnecessary objects After previous example we were left with ticks for years. We didn’t group them so they are in the wrong place. Are they necessary for the figure? If not, remove Select one of the ticks, then: Select – Same - Appearance All the ticks and lines are now selected. Deselect what you want to keep and delete rest.

Changing colours To change colors of the bars, select one bar or the color in legend, then: Select – Same – Fill color This is easier if you ungroup the bars/legend first Select the colour of your liking and repeat for other colours If you’re interested, colorbrewer2.org offers a range of nice color schemes to be used particularly in mapping

Adjust artboard By clicking the Artboard symbol in the left toolbar, you can adjust it

Export figure Once you are happy on your figure, you can export it as png, for example, to be used in a document File – Export… To crop the exported figure to art board, you can tick the Use artboards option
