help on a broken line

[dan ramon]

Hi i am wondering if somebody could help me change the blue broken line into a straight line, because as far as i have read, brokenlines are drawn if there is missing data, but in my code there is no missing data, you can view the picture here http://www.shareapic.net/content.php?id=16680629&owner=steelwater

<?php
//Include the code
require_once 'phplot.php';

//Define the object
$plot = new PHPlot(1200);

//Set titles
$plot->SetTitle("January 2009 WMS -1a Au");
$plot->SetXTitle('Accurassay Job Number');
$plot->SetYTitle('Concentration (ppm)');

//straight lines data
$lines_data = array(
array('200844812',0.18,.22,.3,.38,.42),
array('',0.18,.22,.3,.38,.42),
array('200844840',0.18,.22,.3,.38,.42),
array('200844841',0.18,.22,.3,.38,.42),
array('200844849',0.18,.22,.3,.38,.42),
array('200844306',0.18,.22,.3,.38,.42),
array('200830265',0.18,.22,.3,.38,.42),
);

//points data
$points_data = array(
array('200844812',0.357519231),
array('',.452),
array('200844840',0.268557692),
array('200844841',.684),
array('200844849',.50),
array('200844306',.135),
array('200830265',1.300403846),
);

$plot->SetPrintImage(0);
$plot->SetDrawBrokenLines(false);
$plot->SetPrecisionY(2);
$plot->SetBackgroundColor('grey');
$plot->SetXLabelAngle(90);
$plot->SetXDataLabelPos('plotdown');
//$plot->SetPlotAreaWorld(null,-1.300403846, null, 50);

points chart

$plot->SetPlotAreaPixels(125, 80, 1150, 320);
$plot->SetDataValues($points_data);
$plot->SetXTickLabelPos('none');
$plot->SetXTickPos('none');
$plot->SetDataColors(array('blue'));
$plot->SetPlotType('points');
$plot->DrawGraph();

end points chart

lines chart

$plot->SetDataValues($lines_data);
$plot->SetDataColors(array( 'red', 'green','blue', 'green', 'red'));
$plot->SetXTickLabelPos('none');
$plot->SetXTickPos('none');
$plot->SetPlotType('Lines');
$plot->DrawGraph();

end lines chart

Output the image now:

$plot->PrintImage();

Hi.

Thanks for the big help, i used $plot->SetLineStyles( array( "solid", "solid", "solid")); and it worked perfectly :)

Try this Method;

function SetLineStyles($which_ls=NULL)

$which_ls is an array of Strings where each string is either the word "solid" or "dashed".

Have a look in the phplot.php file for this (line 170 on my machine):

var $line_styles = array('solid', 'solid', 'dashed'); // single value or array

This is the default, so the third line will be dashed by default.

So you can add to your code:
$plot->SetLineStyles( array( "solid", "solid", "solid"));
