Flash chart (from clientraw files) - OFC

[steve26]

Hi all !
Who knows OFC ? Open flash chart
I discovered this open source script last week, and i found it interesting !

Here are somes samples graphs :
http://pullmonkey.com/projects/open_flash_chart
http://noteplog.com/projects/gallery-open-flash-chart.php

And here, i create (quickly) a chart of outside temperature (last 24h)

http://www.valentinois.net/forums/weatherd/31434/ofc/outside-temp.php?lang=en (same page, in english too)
http://www.valentinois.net/forums/weatherd/31434/ofc/outside-temp.php?lang=fr (in french)

I think that's a good starting point to create beautiful and usefull charts, and insert them where you want in your website.

EDIT : ofc 2 available : http://teethgrinder.co.uk/open-flash-chart-2/

If someone wants to test the 2 charts visible in my first post, you can download this file :
http://www.valentinois.net/forums/weatherd/31434/ofc.zip



Unpack the ofc.zip archive on your webserver.
Edit /clientraw_data.php to change the clientraw files folder.
Call http://yourwebsite/ofc/outside-temp.php to see the 2 charts (for outside temp, in english) !
And http://yourwebsite/ofc/outside-temp.php?lang=fr to display charts in french.

There are some comments in php files.
I create 2 languages files, but the french file is not yet fully translated. (only 2 or 3 words for my tests).

Y-axis is automatically adjusted with a calculated min and max value.

Code: [Select]

$ymin = round(min($data_array)); //get the min outside temp
$ymax = round(max($data_array)); //get the max outside temp
$g->set_y_min( $ymin-1 );
$g->set_y_max( $ymax+1 );

Thanks all for the useful information and samples, I never heard before about this graph tool.
I put in use the sample you submit and I'm now learning how to change colors, chart type etc.

I wonder about your opinion between this tool Vs. JPGraph.

Greetings,

Mario

I too have had a play with this new tool. The graphs are very good but I think the main difference between this and JPGraph seems to be the animation of the plot point data appearing as you mouseover. Currently I'm not sure that the graphs refresh data like they do in WDL without a refresh of the page. If they can be updated as the clientraw files update without the user doing anything (AJAX perhaps) then they would have their place for showing near realtime data like in clientraw, not sure about the data in the other files as it does not change enough. I think in general I cannot see any pressing reason to change from JPGraph at present, however if starting out from scratch then both would be equally good candidates to look at.

[strandvejr]

Hi,

Great feature - BUT:

I cant get it to display anything. I followed all the directions from both Pinto and Steve - but no luck. It seems like that the flash isnt loading.

Here is the testfile on my site www.strandvejr.dk/chart-test.php and another one www.strandvejr.dk/ofc/outside-temp.php

Here is a part of my code in the chart-data.php

Code: [Select]

<?php
//Thanks to Kevin Reed from http://TNETWeather.com
//for the script to import the weather data into arrays
$hostloc = "./";
$clientrawextra = get_raw("${hostloc}clientrawextra.txt");

My clientraw files is in the root directory.

Any idea whats wrong and why I cant display the flash chart? I have a flash player installed at my computer.
