How to plot dymanic pie chart from text file?

[sean kwok]

Hi, is there anyway to make the file reader read the text file dymanic?

Here are the codes.

<?php
 
 // Standard inclusions   
 include("pChart/pData.class");
 include("pChart/pChart.class");
 
     $file = "C:\Log\NMS-Television2011101416.txt"; 
 
  $Tv = count(file($file)); 
 
  echo "$Tv";
  $file = "C:\Log\NMS-Games2011101315.txt"; 
 
  $Games = count(file($file)); 
 
  echo "$Games"; 
 
  $file = "C:\Log\NMS-Film2011101416.txt"; 
 
  $Film = count(file($file)); 
 
  echo "$Film"; 
 
  $file = "C:\Log\NMS-Pulishing2011100714.txt"; 
 
  $Pulishing = count(file($file)); 
 
  echo "$Pulishing"; 
 
   $file = "C:\Log\NMS-Animation2011101116.txt"; 
 
  $Animation = count(file($file)); 
 
  echo "$Animation"; 
 
   $file = "C:\Log\NMS-Distribution_Media_Services2011101014.txt"; 
 
  $Distribution = count(file($file)); 
 
  echo "$Distribution";
 
   $file = "C:\Log\NMS-Broadcasting & Technology2011101315.txt"; 
 
  $Broadcasting = count(file($file)); 
 
  echo "$Broadcasting"; 
 
 // Dataset definition 
 $DataSet = new pData;
 $DataSet->AddPoint(array($Tv,$Games,$Film,$Pulishing,$Animation,$Distribution,$Broadcasting),"Serie1");
 $DataSet->AddPoint(array("Television","Games","Film","Pulishing","Animation","Distribution","Broadcasting"),"Serie2");
 $DataSet->AddAllSeries();
 $DataSet->SetAbsciseLabelSerie("Serie2");
 
 // Initialise the graph
 $Test = new pChart(800,500);
 $Test->drawFilledRoundedRectangle(7,7,413,243,5,240,240,240);
 $Test->drawRoundedRectangle(5,5,415,245,5,230,230,230);
 $Test->createColorGradientPalette(195,204,56,223,110,41,5);
 
 // Draw the pie chart
 $Test->setFontProperties("Fonts/tahoma.ttf",8);
 $Test->AntialiasQuality = 0;
 $Test->drawPieGraph($DataSet->GetData(),$DataSet->GetDataDescription(),180,130,110,PIE_PERCENTAGE_LABEL,FALSE,50,20,5);
 $Test->drawPieLegend(400,15,$DataSet->GetData(),$DataSet->GetDataDescription(),250,250,250);
 
 // Write the title
 $Test->setFontProperties("Fonts/MankSans.ttf",10);
 $Test->drawTitle(10,20,"Number of View",100,100,100);
 
 $Test->Render("example10.png");

all file reading are dynamic.

What is your problem??
reading the file or creating the pie chart

[sean kwok]

@johny10151981
I want the program to find the file itself. For example, there is many type of files in the folder, sort by date, if i want to call a few file out it will auto be sort into the pie chart.

HI SEAN ,
why dont you store the name/path of the file somewhere and retrieve it at the time of reading it .

@omerbutt
Those text file is save in a folder but i have no idea how to retrieve it dynamic.
For example, i need a from today and ytd files it will automatically those text file in and generate the chart.

[omerbutt]

weel what i am getting from your reply is that,
the file is saved inside a folder. But is the system saving the file? or the file is saved by some person or you manually? , if the system is saving the file means there is another process that writes the data inside a file and saves it then you need to save the name of the file inside the db and retrieve it later, if i didnt get you right , do correct me .

@omerbutt
Yeah you are right, the file is saved inside a folder by a system, it records the number of use of a program per hourly and name the file in YYYYMMDDHH format. It is not acutally a db, a folder rather.

Now i got to do is get those files from the folder based on the file name automatically, for example i want file from 2pm to 6pm, then those file will be place in the code automatically and generate into a pie chart.

[omerbutt]

you need to have some thing to track the filenames as you said you need the file of 2pm to 6pm then why not use the

filemtime()
 

to track which files were written at the given time
see the manual here

you can even look at the

filectime()
stat()
 

on the given link

@omerbutt
ya i do need to track the files i need and extract it to generate a pie chart.

[omerbutt]

did it worked out for you sean , do ell me when you are done with it , or in case you got some problem
reagrds,

[sean kwok]

Ok i am still trying it out, will get back to you tmr. Thanks for the help!

[sean kwok]

Based on what i have learn so far, i still have to hard code in the textfile myself. My requirement doesn't allow me to do that, it will generate file every hour when the program start running.

Correct me if i'm wrong, Thanks.

[omerbutt]

Hi
cant you have a cron job type something that would trigger to save the file name when the file is created?........if its a local computer the you can use scheduler and remote mysql connection to update the live db .......are you getting what i am trying to say ?
