Exporting data to create charts in excel

Recommended Posts

Hi ,

 

I am creating charts(pie chart) with my php code which gets data from database and chart the respective values  .

 

I want to export these charts , or to create this chart in Excel by Clicking  a button from web .

 

I have seen it done on some website which I dont remember .

 

Can anyone suggest what will be the best solution for it ?

 

Thanks

It's perfectly straightforward to generate an Excel workbook using a library such as PHPExcel.

How you do the charting depends on exactly what charts you need; but the easiest method is to generate the chart as an image file (using PHP and GD, and whatever charting libraries you have available), and then to embed that gif, jpg or png file as an image in the workbook.

Work on actually handling Excel charts within PHPExcel (which would allow reading and writing of chart streams from within the PHP code) is in the very early stages of prototyping, but won't be available in any public release for a long time yet.
