There are basically two main categories of charts: 2D and 3D charts. For each category,
    there are several types:
    
    - 
3D Histogram, Pie, Doughnut, Strips
    - 
2D Histogram, Pie, Lines, Legend
    
    To edit a linked chart:
    
    1. Double click on the chart
        or
    2. Right click on the chart to open the context menu and click on "Redesign Multichart
    Linked to grid"
    
    When the Chart Dialog opens up, it is important to know how to move and resize the
    charts:
    
    
Move: Ctrl Drag
    
Resize: Mouse wheel
    
    For 2D charts: Ctrl-Right Drag
    
    Font resize: Use the chart dialog or, for quick global font changes, there are two
    buttons on the designer
    
    
Rotation (3D charts): Drag
    
    
    
Dialogs
    
    There are 2 main dialogs:
    
    1. 
Section and Colors: This is 
shared among charts 
    and controls the measures and values
    that are represented. Here you can select or deselect the measures or the values
    that have to be displayed. Also, colors of the single values can be adjusted.
    
    2. 
Properties: This dialog is chart-specific. There is one different dialog for each chart type and it controls properties
    that are specific of each chart.
    
    
 
    
    
    
    For each chart there are several properties which can be set and that can affect
    the shape, orientation, lighting of the chart. We leave to the use to make experiments
    and find out about them. Let your creativity flow.
    
    
    
Legend for 3D charts
    
    To add a 
Legend to 3D chart type, right click on the chart to open the context menu
    and click on "Generate Legend Clone chart". This is actually just a shortcut to create a
    chart based on the same data, but with a different type (legend type). In fact we consider, conceptually, a legend like another chart type, and not an accessory of a chart.
