Method Detail

Image_Graph_Plot (Constructor) [line 118]

Image_Graph_Plot &Image_Graph_Plot(

&$dataset, [string
$multiType = 'normal'], [string
$title = ''], Image_Graph_Dataset
$dataset)

PlotType [Constructor]

Valid values for multiType are:

'normal' Plot is normal, multiple datasets are displayes next to one another

'stacked' Datasets are stacked on top of each other

'stacked100pct' Datasets are stacked and displayed as percentages of the total sum

I no title is specified a default is used, which is basically the plot type (fx. for a 'Image_Graph_Plot_Smoothed_Area' default title is 'Smoothed Area')

Parameters:

Image_Graph_Dataset	`$dataset`	—	The data set (value containter) to plot or an array of datasets
string	`$multiType`	—	The type of the plot
string	`$title`	—	The title of the plot (used for legends, Image_Graph_Legend)
	`&$dataset`	—

&$dataSelector, DataSelector
$dataSelector)

Sets the dataselector to specify which data should be displayed on the plot as markers and which are not

Parameters:

setMarker [line 190]

void &setMarker(

&$marker, Marker
$marker)

Sets the marker to 'display' data points on the graph

Parameters:
