The gChartTool Class

Core Public Methods In The gChartTool Class

This list shows the basic methods required to create a Chart/Table

Method	Parameter	Description
drawPage		An all-encompassing function that produces a complete html page, suitable for embedding in an IFRAME
getGoogleJsapi		Returns a string with the html necessary for embedding the necessary external javascripts to produce a chart
getVizualizations		Gets a list of available packages with their Google types and packages. Only one package can be loaded into a single page. This means, for example, that Bar Chart and a Geo Chart cannot be embedded into a single page at the same time. This is a limitation of Google Charts. To avoid this, charts can be embedded into iframes.
loadGoogleChart		Returns a string with the html necessary for creating a Google Chart embedded into your own page.
setAllTableColumns		Sets all table Column Descriptors. The data supplied is a PHP array of data, as described above.
setAllTableRows	array	Sets all table rows. The data supplied can either be a PHP array of data, as described above, or a string containing a Google Dataset.
setChartDivId	string	Sets the ID of the Div where a google chart will be presented when acquiring the chart data with Ajax
setChartOption	array or string pair	Sets either a single, or array of options that affect the presentation of the graph or table.
getGoogleLiteralString		Returns correctly formatted data from an ajax server program to a client
mergeNextDataSet	array	Merges a new set of columns onto the data
setSeriesOption	array or string pair	Sets either a single, or array of options that override the default presentation of series elements. A Series is effectively a Column of Data. See the combo.php example for a more detailed explanation
sethAxisOption	array or string pair	Sets either a single, or array of options that affect the presentation of the graph horizontal Axis.
setJsonURL	string	The URL from which the Chart will receive Ajax data
setvAxisOption	array or string pair	Sets either a single, or array of options that affect the presentation of the graph vertical Axis.
setVizualization	string	Sets the Type of chart to display, e.g. table, pie, bar, scatter.

	ajax	Tells the chart to use a URL to get the Chart Data

setChartHeight	integer	Sets the chart height. The Parameter is ignored if the Drawpage function is used.
setChartWidth	integer	Sets the chart width. The Parameter is ignored if the Drawpage function is used.
setIdentifier	string	This appends the string to each chart element and javascript function. This is only necessary if embedding multiple charts into a single page, to prevent duplication of function names.
