Show tick marks for the x or value axis: Click the Tick Marks pop-up menu, then choose a location.
Show or remove reference lines
You can add reference lines to a chart to mark the average, median, minimum, and maximum values. Reference lines make a chart easier to interpret at a glance and can help you compare the values in the chart to a benchmark value.
All chart types can have reference lines except stacked charts, 2-axis charts, 3D charts, pie charts, and donut charts. A chart can have up to five reference lines.
Click the chart to select it.
In the Format
sidebar, click the Axis tab, then click the Value button near the top of the sidebar.Click the disclosure arrow next to Reference Lines, then choose any of the following types of reference lines from the pop-up menu:
Average: A line that runs through the mean value of the data
Median: A line that runs through the middle value of the data
Minimum: A line that runs through the lowest value of the data
Maximum: A line that runs through the highest value of the data
Custom: A line that runs through a value you specify
To show what the reference line represents, select the Show Name and Show Value checkboxes.
To change the settings for a reference line, click the line, then use the controls in the Reference Line tab in the sidebar on the right.
Note: When you drag the slider on an interactive chart to view different data sets, its reference lines move.
To remove a reference line, click the line to select it, then press Delete on your keyboard.
Show or remove error bars
Error bars give you a general impression of your data’s accuracy. They’re represented as small marks whose length indicates the amount of uncertainty associated with a given data series (the data’s variability). You can add them to 2D line charts, area charts, bar and column charts, stacked bar and column charts, bubble charts, and scatter charts.
Click the chart, then in the Format
sidebar, click the Series tab.Click the disclosure arrow next to Error Bars, then click the pop-up menu and choose a type of error bar.
For scatter and bubble charts, click a pop-up menu below X Axis Error Bars or Y Axis Error Bars, then choose a type of error bar.
Click the second pop-up menu, choose how error values are calculated (for example, as fixed values or percentages), and change the range of variability you want to display.
To change the look of the error bars, click an error bar so you see white dots at either end.
All error bars for that data series are selected.
Use the controls in the Bar Style and Shadow sections of the sidebar to make changes.
Only the error bars for the selected data series are modified. To change error bars for another series, click one of its error bars, then make changes.
When you create a chart, Auto-Fit is automatically turned on for error bars to prevent overlap. To see all error bars, deselect the checkbox next to Auto-Fit.
To remove error bars, click the chart, click an error bar, then click the Error Bars pop-up menu in the sidebar and choose None.
Show or remove trendlines
Trendlines show you the overall direction (or trend) of your data. Trendlines appear in bar, line, scatter, bubble, column, and area charts.
Click the chart, then in the Format
sidebar, click the Series tab.Click the disclosure arrow next to Trendlines, then click the pop-up menu and choose a type of trendline.
