Class usage and OverviewAccumulated bar plot.
Used to create a line plot where each individual data point is the sum of the individual series data points.
- Unlimited number of series

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.
list($xmax,$ymax) = $acclineplot->Max();
Return the min value of all data points in plot.
Description:Takes into account all series and returns the minimum Y and X value. Used internally to determine autoscaling.
list($xmin,$ymin) = $acclineplot->Min()
Enable interpolate mode
|| ||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.
|| ||Array of line plots to use|
Description:Creates a new accumulated line plot from a number of line plots.
$line1 = new LinePlot($datay1);
$line2 = new LinePlot($datay2);
$aline = array($line1,$line2);
$acclineplot = new AccLinePlot($aline);
