Class usage and Overview
Accumulated bar plot.
Used to create a line plot where each individual data point is the sum of the individual series data points.

Features:

1. Unlimited number of series

Class Methods

AccLinePlot ::
Max()
Return the max value of data points in plot.

Description:
Takes into account all series and returns the maximum Y and X values for all the data series. Used internally to determine the autoscaling.
See also:

- Plot::Max()

Example:

list($xmax,$ymax) = $acclineplot->Max();

AccLinePlot ::
Min()
Return the min value of all data points in plot.

Description:
Takes into account all series and returns the minimum Y and X value. Used internally to determine autoscaling.
See also:

- BarPlot::Min()
- Plot::Min()

Example:

list($xmin,$ymin) = $acclineplot->Min()

AccLinePlot ::
SetInterpolateMode($aIntMode)
Enable interpolate mode

Argument | Default | Description
--- | --- | ---
$aIntMode |  | TRUE=Enable interpolation

Description:
When plotting accumulated line plots which have NULL values as data (i.e. '-') they will distort the accumulated plot since they will in effect be interpretated as having value 0. This means that there will be a drop in the plot. The only way to avoid this is to calculate the intermediate value. This can be achieved by calculating a linear interpoaltion for the missing value(s). Calling this method will replace all '-' values with an interpolated value.

Example:

$accline->SetInterpolateMode()

AccLinePlot ::
__construct($plots)
Constructor

Argument | Default | Description
--- | --- | ---
$plots |  | Array of line plots to use

Description:
Creates a new accumulated line plot from a number of line plots.
See also:

- LinePlot::LinePlot()

Example:

$line1 = new LinePlot($datay1);
$line2 = new LinePlot($datay2);
$aline = array($line1,$line2);
$acclineplot = new AccLinePlot($aline);
