jpGraph can't include PHP file

由 邮差的信 提交于 2019-12-12 01:09:52
问题 I am trying to include one PHP file in another PHP file that creates a jpGraph image (The reason is that I am loading mySQL data for the chart, and I want to put the login credentials into a separate file) I know that the chart is created (because a correct image file is created) but the chart does not show up in the web page. Here is a simplified code example: login.inc.php <?php $lhostname="localhost"; $lusername="joeschmack"; $lpassword="autumnleaf"; $ldatabase="customers"; ?> accbarex1

问题 I cannot find any link to the official jpgraph forum. Moreover, the last "real" release was made more than one year ago. Is this library dead? If so, what library could be used in its place with minimal disruption to existing code? Perhaps there has been a fork that I'm not finding? 回答1: Since they've been purchased by asial the development stopped. There is no fork as it's a pure commercial product now. However there are other really professional PHP solutions around. If you don't need PHP,

问题 I am trying to change the color of the margin on a jpgraph. I cannot seem to figure it out. I tried $graph->SetMarginColor("khaki:0.6"); but that seemed to do nothing. below is the code that generates an example chart as well as the sample output. I am using jpgraph 3.5 if that helps. $datay1 = array(20,15,23,15); $datay2 = array(12,9,42,8); $datay3 = array(5,17,32,24); // Setup the graph $graph = new Graph(300,250); $graph->SetScale("textlin"); $theme_class=new UniversalTheme; $graph-

A little background I am attempting to migrate a project built with Symfony 1.2 from one server to another. One of the functions of the project is to build a graph (originally done with JpGraph 2.3.5). The graph does not display as intended without modifications to the code and am looking for some insight on what I might be overlooking. Images are linked due to not having enough points to post. Graph Image Gallery The following graph is what is generated by the code block below <?php public function Graph($section) { $report = $section->getReport(); $this->crews = array(); foreach ($section-

How to embed a graph (jpgraph) in a web-page

由 烈酒焚心 提交于 2019-12-04 21:19:51
问题 I am using this script which is one of the examples provided by jpgraph itself. When I put this on a web-page (blank) by itself, it's drawing the graph. But when I embed the code in already existing web-page (with some content), it ain't drawing a graph. GD is already enabled according to phpinfo(). Iam using jpgraph 3.5.0b1. 回答1: The problem is that you are mixing HTML/text output with image output. Any time you have a PHP script generate graphical content you have to handle the output

Jpgraph wont change colors on my barplot

问题 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. 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. I'm not sure how to

问题 The problem is that the JpGraph is not displayed correctly on my web-page. The strange thing is that if I run the above code in isolation, then it works. But if I insert it in my main code, it fails producing the above-shown message. P.S. I'm using 'ob_start();', but it does not solve the problem. // A new graph with automatic size $graph = new GanttGraph (0,0, "auto"); // A new activity on row '0' $activity = new GanttBar (0,"Project", "2001-12-21", "2002-02-20"); $graph->Add( $activity); //
