Last Updated: May 7, 2024 Fact Checked

Are you having trouble changing the scale of the horizontal (X) axis in Excel? You're not alone! If you're not seeing options for changing the range or intervals on the x axis, or you just can't customize the scale how you want, you might need to switch to a chart type that supports custom scaling on the X axis. This wikiHow article will teach you how change the scale of the X axis for dates, text, and numerical values in Microsoft Excel.

- For example, if you want to show a larger tick mark every 30 days and a smaller one every 5 days, you'd type a "30" into the "Major" field, a "5" into the "Minor" field, and chose Days for each.

Set where the vertical axis (Y) crosses the horizontal axis.
- If you're working with dates, you can set the Y axis to cross between dates, at a particular date, or at the maximum (last) date.
- If you're working with text categories, you can set the Y axis to cross at a particular category number, at the maximum (last) category, or just leave "Automatic" selected and adjust as necessary.
If you want to switch the order of the values on the X axis, check the box next to "Dates/Categories in reverse order" below the "Axis position" section.
10
Change your tick mark settings. Expand the "Tick Marks" section and customize:
- Dates: You can adjust the position of both the major and minor tick marks, or opt to leave either type out.
- Text: Enter a value into "Interval between marks" to customize the intervals between tick marks, then use the "Major" and "Minor" menus to adjust the positioning of the larger and smaller tick marks.
11
Customize the label settings. Expand the "Labels" menu to find options for the labels on the X axis.
- Dates: You can customize the placement of the dates using the "Label Position" menu.
- Text: You can specify the interval between labels by choosing Specify interval unit and entering a number. You can also customize the distance between the label and the axis, as well as the label's position.
12
Format the numbers. The chart automatically inherits the number format you used in your data. If it doesn't look right, use the options in the "Number" section at the bottom to choose a different number format.
- You can also use the icons at the top of the "Format axis" panel to customize other details of the X axis, such as the alignment and fill. ^{[5]

- If you want to reverse the order, just scroll down and check the box next to "Values in reverse order."
- If you check the box next to "Logarithmic scale," each value on the X axis will be multiplied by the value you enter into the "Base" field.
6
Specify the tick mark interval. You'll set the intervals between tick marks by entering values into the "Major" and "Minor" fields.
- For example, if you want to show a larger tick mark every 100 sales and a smaller one every 50 sales, you'd type a "100" into the "Major" field, and a "50" into the "Minor" field.
- To change the orientation of the tick marks, use the options in the "Tick Marks" section a little bit below.
