Tick Marks on Chart Axes in PowerPoint 2010 for Windows

Charts are a visual representation of data, and when seen on a PowerPoint slide from afar, you make out the value of a series by exploring where exactly it's placed vis-à-vis the axis. Of course, if your chart has data labels, then this is less of an issue -- however, typical charts such as the one shown in Figure 1, below have no data labels. For such a chart, you'll notice that the column representing Grapes in 2009 is a little taller than the value 4 in the adjacent axis, indicating a rough value of around 4.25. We're still not sure -- and the Tick Marks placed on the axis will help us get a better idea.

There are two types of Tick Marks -- Major and Minor. In Figure 1 below -- we chose two colors to highlight these tick marks because most chart types show two types of tick marks on axes -- Major (highlighted in red) and Minor (highlighted in blue).

Figure 1: Major and Minor Tick marks on chart axes

Major tick marks are indications on an axis that show up:

• Between the categories on the Horizontal axis, and,
• Besides Major Unit values on the Vertical axis

Both are shown in Figure 1, above (highlighted in red).

Major tick marks are the indications on an axis that show up between categories on the Horizontal axis, and, besides Major Unit values on the Vertical axis as shown in Figure 1, above (highlighted in red).

Minor tick marks are those tick marks that appear between the Major tick marks on an axis -- typically PowerPoint charts do not display Minor tick marks, but we enabled them in the chart shown in Figure 1 above (highlighted in blue). Minor tick marks help users measure the distance between the Major tick marks.

If you look at this picture of a ruler (picture sourced from Office.com), you'll recollect that both Major and Minor tick marks have been available in all types of rulers we have used -- even the rulers used in primary school.

In this tutorial we will learn how to show/hide these tick marks and also where you display these Major and Minor tick marks:

1. Open your presentation and insert a chart on your slide, as shown in Figure 2. Just accept defaults, as we did for the basic Column chart shown in Figure 2. The default position of Tick marks depends upon the chart type you are working with -- also notice that Minor tick marks are hidden by default for a Column chart.

2. Click and select the chart axis for which you want to change the position of Tick marks -- right-click to bring up a context menu as shown in Figure 3. From this context menu, chose the Format Axis option (refer to Figure 3 again).

   Note: Can't see the Horizontal gridlines in Figure 3? We have disabled them so that the Tick marks in various positions are clearly visible in our screenshots.
3. This summons the Format Axis dialog box -- in this dialog box, make sure that Axis Options is selected within the sidebar as shown in Figure 4. Locate the Major tick mark type and Minor tick mark type options (highlighted in red within Figure 4).

4. Click the downward pointing arrow associated with either Major tick mark type or Minor tick mark type. You can see that there are four types of Major and Minor tick marks as shown in Figure 5.

   Let's explore them in the order they appear in Figure 5, above:
   

   A. None

   As the name suggests, this option hides Tick marks.
   

   B. Inside

   Positions the Tick marks inside the plot area.
   

   C. Outside

   Positions the Tick marks outside of the plot area.
   

   D. Cross

   Places the Tick marks on the axis they overlap with the axis, crossing it.

Figure 6 shows the positions of Major tick marks on Value Axis when we selected the None, Inside, Outside, and Cross options.

Figure 7 shows the positions of Minor tick marks on Value Axis when we selected the None, Inside, Outside, and Cross options.

Figure 8 shows the positions of Major tick marks on Category Axis when we selected the None, Inside, Outside, and Cross options.

Figure 9 shows the positions of Minor tick marks on Category Axis when we selected the None, Inside, Outside, and Cross options.
