3D Pie Chart Documentation

Set a Data Value

set_datavalue(int pienum, int segment, String value, boolean repaint)

This method enables any of the graph data values to be changed.

pienum - this specifies the pie number of the pie to be changed.

segment - this specifies which segment within the pie is to be changed. eg. 3 would represent the 3rd segment value of the pie.

value - the value to which this data item should be set.

repaint - specifies whether the graph should be redrawn once the data value is set. Value can be either "true" or "false"

e.g. to add a button to your web page which will update the second data value of series 1,

<input type="button" value="Update Data Item" onclick="document.applets['GRAPH'].set_datavalue(1,2,"52.4", true);">

Reload Data

reload_data(String value, boolean repaint)

This method enables all the graph data to be reloaded from a file or server side process. This method is particularly useful where you wish the chart data to be refreshed either by a user action or time interval.

value - the URL specifying the location of the data file or server side process supplying the data

repaint - specifies whether the graph should be redrawn once the data is loaded. Values may be either "true" or "false".

Set a Parameter (graph property)

set_parameter(String parmname, String value, boolean repaint)

This method enables any of the Graph Parameters to be modified dynamically during runtime.

parmname - this is the property name as defined in the Parameters section.

value - the value which this property should be set.

repaint - specifies whether the graph should be redrawn once the parameter is set. Value can be either "true" or "false"

e.g. to add a button to your web page which will turn the 3D effect off,

<input type="button" value="3D Off" onclick="document.applets['GRAPH'].set_param('3D', 'false', true);">

Size Reset

size_reset(int width, int height, boolean repaint)

This method enables the display area (size) of the pie chart to changed.

width - specifies the new width in pixels

height - specifies the new height in pixels

repaint - specifies whether the graph should be redrawn once the size is changed. Value can be either "true" or "false"

e.g. to add a button to your web page which will change the size to 200x200 pixels,

<input type="button" value="Set Size" onclick="document.applets['GRAPH'].size_reset(200, 200, true);">
