POJpgraph wont change colors on my barplot
text
Body
copied!<p>I'm just getting started with jpgraph and XAMPP I was looking to make a barplot. As I was reading some articles on the web it said you could pass in an array of colors to setfillcolor so that each bar would be a different color. However whenever I pass it color the graph won't change from its default color of light blue.</p> <p>The graph respond s to changes in data but not changes to color. I tried with an accumulated bar graph example and that seems to be color responsive.</p> <p>I'm not sure how to diagnose a problem like this. Help please!</p> <p>Code Below(Example from the Jpgraph documentation with color changed from orange to #B0C4DE [orange from the original example doesn't show up]):</p> <pre><code><?php // content="text/plain; charset=utf-8" require_once(dirname(__FILE__)."\lib\jpgraph-3.5.0b1\src\jpgraph.php"); require_once(dirname(__FILE__)."\lib\jpgraph-3.5.0b1\src\jpgraph_line.php"); require_once(dirname(__FILE__)."\lib\jpgraph-3.5.0b1\src\jpgraph_bar.php"); $datay=array(2,3,5,25,15,6,3); $datax=array('Jan','Feb','Mar','Apr','May','Jun','Jul'); // Size of graph $width=400; $height=500; // Set the basic parameters of the graph $graph = new Graph($width,$height,'auto'); $graph->SetScale('textlin'); // Rotate graph 90 degrees and set margin $graph->Set90AndMargin(50,20,50,30); // Nice shadow $graph->SetShadow(); // Setup title $graph->title->Set('Horizontal bar graph ex 1'); $graph->title->SetFont(FF_VERDANA,FS_BOLD,14); // Setup X-axis $graph->xaxis->SetTickLabels($datax); $graph->xaxis->SetFont(FF_VERDANA,FS_NORMAL,12); // Some extra margin looks nicer $graph->xaxis->SetLabelMargin(10); // Label align for X-axis $graph->xaxis->SetLabelAlign('right','center'); // Add some grace to y-axis so the bars doesn't go // all the way to the end of the plot area $graph->yaxis->scale->SetGrace(20); // We don't want to display Y-axis $graph->yaxis->Hide(); // Now create a bar pot $bplot = new BarPlot($datay); $bplot->SetFillColor("#B0C4DE"); // ALSO tried: // $bplot->SetColor(array("red","green","blue","gray")); $bplot->SetShadow(); //You can change the width of the bars if you like //$bplot->SetWidth(0.5); // We want to display the value of each bar at the top $bplot->value->Show(); $bplot->value->SetFont(FF_ARIAL,FS_BOLD,12); $bplot->value->SetAlign('left','center'); $bplot->value->SetColor('black','darkred'); $bplot->value->SetFormat('%.1f mkr'); // Add the bar to the graph $graph->Add($bplot); // .. and stroke the graph $graph->Stroke(); ?> </code></pre>
