Chart Type Column and Bar
On the first page of the Chart Wizard you can choose a chart type.
Column
This type shows a bar chart or bar graph with vertical bars. The height of each bar is proportional to its value. The x axis shows categories. The y axis shows the value for each category.
Normal - this subtype shows all data values belonging to a category next to each other. Main focus is on the individual absolute values, compared to every other value.
Stacked - this subtype shows the data values of each category on top of each other. Main focus is the overall category value and the individual contribution of each value within its category.
Percent - this subtype shows the relative percentage of each data value with regard to the total of its category. Main focus is the relative contribution of each value to the category's total.
You can enable a 3D view of the data values. The "realistic" scheme tries to give the best 3D look. The "simple" scheme tries to mimic the chart view of other Office products.
For 3D charts, you can select the shape of each data value from Box, Cylinder, Cone, and Pyramid.
Bar
This type shows a bar chart or bar graph with horizontal bars. The length of each bar is proportional to its value. The y axis shows categories. The x axis shows the value for each category.
The subtypes are the same as for the Column type.
