It is recommended that you visit the new Daisy 2003 Web Site and look at Daisy Grids.

Daisy has been designed to display a database in a Daisy Chart, which can then be investigated with the mouse to display the underlying data in simple Daisy Grids.

• A Typical Daisy Chart
• Investigating a Node
• Displaying the Records
• Displaying the Links
• Selecting on More Than One Node
• Using Excel Workbooks instead of Daisy Grids

The graphic below shows a typical Daisy Chart. The data is contained in the file, TelephoneCalls.txt, which is supplied with all copies of Daisy and was drawn using the Date and Time Analysis Template stored in daisyex1.dyt.

It is very much a typical Daisy Chart, that shows the relationship between the Day of the Week and Hour of the Day for a series of telephone calls.

Note the boxes or Nodes, labelled Sun, Mon etc., which are the key to accessing the underlying data.

Click on any Node and a detailed summary will be displayed.

This shows a summary of all the calls made during the fifth hour of the day.

Click on Records on the Node Investigation Summary and they will be displayed in a simple Daisy Grid.

Note the command buttons at the foot of the dialog.

• Print - Prints the data in the Daisy Grid
• Sort - Sorts the data according to the values in any column
• Edit/Save - Edits and saves the data
• Daisy - Draws another Daisy Chart of the data
• Excel - Opens Microsoft Excel on the data
• Find - Searches the data for a particular string

Click on Links on the Node Investigation Summary and they will be displayed in a simple Daisy Grid.

Note that by default Links are shown in decreasing order of weight.

Often you might want to select data from the database, based on two or more Nodes. A typical selection might be all Records that are on a Wednesday between 7 and 8.

Use the Point and Click sub-command in the Selected Records command from the View menu and then follow the instructions. (Alternatively, you can use the shortcut key, Control-R.)

In most cases, you just click on the Nodes you wish to be included in the selection (In this case Wednesday and 7!) and then click anywhere on the background to actually perform the selection.

When you select and display data, it is normally stored in a Daisy Grid, which can then be printed, sorted and processed as was shown above.

You can also use Excel workbooks instead of the standard Daisy Grid.

More details are given in Daisy and Linking to Excel.

Each approach has its advantages. The choice is very much yours!
