Bar graph properties form
The form contains the following:
- Input – the index/number that corresponds to the input variable (read only). At run time (when video is generated) the current value of the input variable will be displayed in the form of a bar graph inside this control. This property can be changed by dragging and dropping the appropriate variable from the variables pane in to the body of the control in the design area. The default value for this is ‘0’ indicating that no input variable has been set.
- Default value (textbox) – This is a default value assigned to the input variable. This will be used to generate the sample that is displayed on the design area.
- Min (textbox) – This is the value of the input variable for which the length of the graph should be 0.
- Max (textbox) – This is the value of the input variable for which the length of the graph should be maximum (full length).
- Start X (textbox) – This is the x coordinate of the top left hand corner of the bar graph
- Start Y (textbox) – This is the y coordinate of the top left hand corner of the bar graph
- End X (textbox) – The value that is contained here depends upon the type of bar graph that has been selected:
horizontal – This is the x coordinate of the top right hand corner of the bar graph
vertical – This is the x coordinate of the bottom left hand corner of the bar graph
- End Y (textbox) – The value that is contained here depends upon the type of bar graph that has been selected:
horizontal – This is the y coordinate of the top right hand corner of the bar graph
vertical – This is the y coordinate of the bottom left hand corner of the bar graph
- Bar width (textbox) – This is the width of the bar graph. When using a horizontal graph, this specifies the width of the graph in the vertical direction (y-axis). When using a vertical graph, this specifies the width of the graph in the horizontal direction (x-axis).
- Bar type (combo box) – There are two types of bar graph;
Horizontal – Here, as the input variable increases, so too does the length of the bar in the horizontal direction (x-axis).
Vertical – Here, as the input variable increases, so too does the length of the bar in the vertical direction (y-axis).
- Colour - This allows you to select the colour of the bar graph
It should be noted that the size of the bar graph can be altered by resizing the control on the design area.
