• Use GRID control (grid32.ocx) to display a series of rows and columns. The intersection of a row and column is a cell.

• Each cell is an Am_Text_Input_Widget

• No GRID control in Amulet

• Send all the data to chart window, when users press “Next” button

• Link the Am_VALUE to Chart Window's

     Bar Chart (Am_Rectangle ) 

     or

     Scatter Chart (Am_Arc)

• Users suggested displaying the chart at the same time the data entry fields are present.
• Amulet allows dynamic linking by constraints

• There is no way to use the “TAB” to move around the cells in GRID control.

• By setting the Am_Tab_To_Next_Widget_Interactor to use “TAB” to move around the cells

• Amulet allows tabbing

• Separate window to select number of lines and points and input legend information
• Information for each bar or line is entered on a separate window

• Ask user for Legend information sooner
• Ask user for number of bars or data sets and points when he enters legend data.
• Information for all bars or lines is entered in one window

• Seems more logical. Gives us a cart name to use while inputting data
• This was done to simplify the interface

• Each set of data points is entered on a separate window

• All data points are entered in the same window

• This was done to simplify the interface

• Button read Data Entry
• Button read Update Finish

• Button reads Next
• Button reads Next

• Consistency

• Use GRAPH control (graph32.ocx) to display the bar char or scatter chart.

• For Bar Chart,

each row of Data Input Window defines an Am_Rectangle.

The Am_WIDTH has a formula to set itself according to the Am_VALUE of Am_Text_Input_Widget

• For Scatter chart,

each cell of Data Input Window defines an Am_Arc.

The Am_LEFT and Am_TOP have formula to set themselves according to the Am_VALUE of Am_Text_Input_Widget

• No graph control in Amulet

• At run time, get all the data from Data Input Window and generate the chart.

• At run time, the chart updated dynamically and automatically according to the users input data in Data Input Window

• Bars in bar chart are dynamically created as user inputs data.
• Points in scatter chart are dynamically created as user inputs data

• Need to go back and forth between Data Input Window and Char Window to modify data and view the result

• Data Input Window and Char Window are displayed on the screen at the same time.
• Ask user for Legend information sooner

• Users suggested displaying the chart at the same time the data entry fields are present
  • Amulet allows dynamic linking by constraints

• There is no way you can program any event on the Graph control. There is no mouse actions on the chart

• Each Am_Rectangle or Am_Arc has a Am_One_Shot_Interactor which handles the change of color.

• It is more direct to select bar or point to change its color than to go back and modify a field.
• Easy to define interactor objects and attach them to graphical objects
