  Error BaseChart.getWidth
Posted by poe on Dec-18-2010 04:24

Hi Peter,
I try to run the Binary Data Series Chart but i get this error:
Fatal error: unknown method BaseChart.getWidth in
C:\\xampp\\htdocs\\greenhvac\\demosite\\charts\\lib\\phpchartdir.php on line 1138
I update the hole lib folder with the latest.
I also find that chartdirr.dll can cause the same issue.
Mi chartdir.dll file is 2.20MB (vs 1.73MB the old ) and phpchartdir.php is 124.86Kb (vs.
111.02Kb the old).
I mention that $dataY and $dataX are arrays with 450 elements.
Thanks
Mircea
Here is the code:
<?php
require_once("lib/phpchartdir.php"); // pentru grafic

if (isset($_GET["start_date"]))
    $selected_start_data = $_GET["start_date"];
else
   $selected_start_data = "2010-11-02"; //data asta este luata din 1BW fisier  adica data
curenta nu cred ca trebuie linia asta de cod

if (isset($_GET["FC"]))
    $selected_FC = $_GET["FC"];
else
   $selected_FC = "1";


$StartDate = $selected_start_data;
$selected_An=substr($StartDate, 0, 4);
$selected_Luna=substr($StartDate, 5, 2);
$selected_Zi=substr($StartDate, 8, 2);

$date= $selected_An."/".$selected_Luna."/".$selected_Zi; //$date = '2007/08/30' asa
trebuie sa fie formatul

$weekday_as_text = date('l', strtotime($date)); // am nevoie cind scriu ziua in grafic

$selected_day_charttime_start = chartTime($selected_An, $selected_Luna, $selected_Zi,
00, 00, 00 );

$selected_day_charttime_end = chartTime($selected_An, $selected_Luna, $selected_Zi,
59, 59, 59 );

TIMPULGRAFIC BETWEEN " . $selected_day_charttime_start . " AND " .

// sa adaugi o linie la grafic

Hi poe,

Please try the original unmodified Binary Data Series sample code that comes with ChartDirector. If the same error occurs, it may be because your code is using an older version of ChartDirector.

To confirm exactly which version of ChartDirector you are using, please use the "ChartDirector/phpdemo/cdinfo.php" that comes with ChartDirector. It will display the ChartDirector version, and also exactly where is the active "chartdir.dll".

(Note: cdinfo.php assumes the ChartDirector library is in "../lib/phpchartdir.php". You may need to modify it to fit your directory structure.)

It is common for people to copy the files in "ChartDirector/lib" to many other directories on the server. So there may be multiple copies of "chartdir.dll" and "phpchartdir.php" in your web site. If you are upgrading from an older verison of ChartDirector, it is possible that some of the DLL copies are not updated, and the PHP happens to be using the non-updated DLL.

Also, depending on how your PHP system is configured, you may need to restart the web server for the updated DLL to take effect. (From my understand of xampp on Windows, you may be unable to update the DLL at all, as Windows may complain that the file is locked by another process. If you can update the DLL freely at any time, may be the server is not using that copy of the DLL at all.)

Peter Kwan

Thanks Peter,
It works fine.

Can you suggest me a way how I can calculate the total time ON and total time OFF ?

Thanks again
Mircea

Hi Mircea,

To calculate the total time ON, you may add all the ON time together. To calculate the total time OFF, you may add all the OFF time together. (You do not need to use ChartDirector to compute or add the time together.)

Hope this can help.
