PHP Charts/Graph (Excel.Application) |
PHP Charts/Graph ทางเลือกในการสร้างกราฟด้วย Excel เป็นทางเลือกหนึ่งที่ผมแนะนำสำหรับผู้ที่เขียน PHP ทำงานบนระบบ Windows เหตุผลเพราะ Excel สามารถทำอะไรได้มากมายที่เรายังไม่ได้เรียกใช้งานความสามารถของมัน โดยการใช้งานจะเรียกผ่าน COM ผ่าน Component ของ Excel.Application ซึ่งจะมี Class และ Library ให้เลือกใช้มากมายยย

จากรูปจะเห็นว่ากราฟถูกเขียนลงไฟล์ Excel (*.xls) ซึ่งถูกเขียนไว้คนล่ะ Sheet
phpExcelCharts2.php ตัวอย่างนี้จะเป็นการเขียนกราฟให้อยู่ใน Sheet เดียวกัน
