Adding and Deleting Chart Series and Categories
When you add a new chart in PowerPoint 2013, you will see that it has its roots in Excel -- all the chart data is also stored within an Excel sheet. When you edit chart data within Excel, the process may not be limited just to changing the values. You many also need to add a new Series or Category. If we use a column chart as an example, Series within your Excel sheet show up as the columns. Categories on the other hand are essentially a set of series.

Creating Curved Shapes
PowerPoint provides an extensive array of built-in shapes which help you create great looking graphics for your slides. You can manipulate these graphics by dragging their yellow squares or combining them -- but at times, you may not achieve the exact appearance you want. For instance, you might want a little curve in your shape edges rather than conventional straight lines. PowerPoint does allow you to tweak and make your shape look more organic than geometric curved lines.

Working with RGB Colors
We already explored what Color Models are and we then looked at the RGB color model that uses three primary colors: Red, Green, and Blue to mix and create almost 16 million colors. All RGB colors have values for all the three option: R, G, and B. Assuming someone has provided you with an RGB value, and asked you to add a rectangle of that color to a slide, then how do you proceed? Let's learn from this tutorial.

Hiding Chart Series and Categories
In PowerPoint, the entire chart data that shows up in the form of series and categories is actually stored within an Excel sheet. These series and categories may show up on your chart in different ways depending upon the chart type. Almost any chart type, even if it is not a column chart, compares one set of values with another. Once you delete any of these values, they no longer show on your chart -- so the level of comparison reduces. However deleting is not always the best option, especially if you want to retrieve those values later whenever required. The solution is to temporarily hide values you no longer need, and then unhide them as and when you want to expose those values.

Drawing Trees
Although most people think of PowerPoint as a slide program, it's also a great drawing program that can in many ways be more easier to use than full-fledged illustration programs. Agreed, PowerPoint is not that full featured as far as drawing goes, but sometimes quick and easy is all you need! In this tutorial, you will learn how to draw a tree with just two simple shapes in PowerPoint 2013.

Text Alignment within Table Cells
As far as the content or even appearance is concerned, an individual cell within a Table in PowerPoint acts just like any other text box. Therefore, various text alignment options used for text boxes work with Table cells too apart for a few exceptions. Once a cell is selected, the Text alignment options for that cell can be found within the Table Tools Layout contextual tab of the Ribbon -- you can find them contained within the Alignment group.
