Does your chart has any data with negative values? PowerPoint by default uses the same fill color for negative values as is used for positive values. Look at Figure 1, below where we have used solid fills for our columns representing a series. Of course, you can override this nature of PowerPoint using the Invert if Negative option, that we last explored at the end of our Changing Fills and Outlines of Charts tutorial. In this tutorial, let us explore this option further.

Where is the Invert if Negative Option?
The Invert if Negative option is only available for column, bar, cylinder, cone, and pyramid chart types. The pie and area chart types do not have this option as they don't plot negative figures.
To use the Invert if Negative option you must have inserted a chart on your slide that has negative values, as shown in Figure 1, above.
Follow these steps to use the Invert if Negative option in PowerPoint 2011 for Mac:
- Select the data series including negative values by clicking on it as shown in Figure 2, below. Alternatively, you can select the data series from the chart elements drop-down list.

- With the data series selected, select either the Chart Layout or the Format tabs of the Ribbon as shown in Figure 3, below. With any of these tabs selected, locate the Current Selection group, that you can see in Figure 3 towards the extreme left. Within this group, make sure that the Chart Elements drop-down list, as shown highlighted in red within Figure 3 is displaying the name of the selected chart element. Then, click the Format Selection button below it as shown highlighted in blue within Figure 3.

- This action summons the Format Data Series dialog box. Make sure that the Fill option is selected in the sidebar, as shown in Figure 4, below.

- Make sure the Solid tab is selected and then select the Invert if Negative check box, as shown highlighted in red within Figure 4, above. Then, click the OK button. This action will change the color of the negative figure column to white, as you can see in Figure 5, below. Compare Figures 5 and 2.

- Want to change the color fill of the negative figure column from white to some other color? Refer to our Changing Color for Negative Data Series of Charts in PowerPoint 2011 for Mac tutorial.
- In the above example, we have used the solid color as fill for the data series. If the fill is a gradient, then the result of selecting the Invert if Negative check box will be little different. Figure 6, below shows a chart with gradient fill used for the data series before applying Invert if Negative.

- If you select the Invert if Negative check box for this chart, the result will look like something that you can see in Figure 7, below. Compare the third column of the chart in Figures 6 and 7.
Figure 7: Negative figure column with gradient fill inverted
- As you can see in Figure 7, above the gradient fill of the column with negative figure has been inverted.
- Save your presentation.
