Question

I’m using JpGraph to make a Gantt chart for a convention. I found this example at the bottom of the page and I’m trying to alter it to what I need displayed. I was able to set the leftMark to the side of the bar that I want the text to appear. However, the text is not within the bar. I tried to change the alignment to "left, top" but I get either an error $bar->leftMark->title->SetTextAlign('left','top');

Fatal error: Call to undefined method Text::SetTextAlign() in
C:\xampp\htdocs\ganttChart\chart.php on line 82

or no effect on the graph.

Please see my example of what I was able to do with the graph: example.

Questions:

1. What classes, includes, or code an I missing in order to complete this task?

2. Do you know of an example that I can follow that has the same effect that I am looking for, described in the paragraph and example above?

I figured this out see my example and code below:Example

code:

<?php // content="text/plain; charset=utf-8"

// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// Reporting E_NOTICE can be good too (to report uninitialized

// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);

// Report all PHP errors (see changelog)
error_reporting(E_ALL);

// Report all PHP errors
error_reporting(-1);



// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
