Format Chart Data Labels in Excel
In PowerPoint even though you can use Category or Series names as Data Labels, most of the time users tend to use Values as Data Labels. Values are typically numbers, and there are many ways in which you can format these Data Labels. You may want to do so for several reasons such as limiting or expanding the number of decimal digits shown, or to show a currency symbol along with the values, or even to show the value in percentage etc. Do note that these format changes can be made both within Excel and PowerPoint -- in this tutorial, we explore how you do so in Excel at the data level (all data for PowerPoint charts resides in Excel).

Changing Chart Types
PowerPoint 2013 provides all the basic chart types such as Column, Bar, Line, Pie, etc. -- and also some advanced charts like Radar, Surface etc. Together, all these chart types work for almost every kind of graphical data representation.

Fills for Shapes
When you insert shapes within a PowerPoint 2013 slide, you will notice that all shapes you insert contain the same fill. Most of the time, the shapes may contain a solid color fill. Similarly, you may insert hundreds of shapes and they all have this same default fill -- have you ever wanted to change this fill to something else? Before we explore changing fills, it is important to understand that the default fill you see for new, inserted shapes is influenced by the Theme applied to your presentation -- all new presentations have a simple Theme applied to them -- this Theme decides the default color or style for the new shape. Thus, all new shapes that you insert will have the same fill.

Add Solid Fills to Shapes
Whenever a new shape is inserted on a slide in PowerPoint 2013, it is filled by default with a solid color (or something else depending on the Theme your presentation is based on). Other than a solid fill type, PowerPoint 2013 provides several more options that let you fill a shape with a picture, a gradient, a pattern, or a texture -- and we have explored these other fill options in our Fills for Shapes in PowerPoint 2013 tutorial. In this tutorial, we'll show you how you can work with solid color fills.
