Column & Bar Chart with data from MySQL database table using PHP pdo and google chart library

Part 1 & part 2 of this tutorial we discussed about how to use google chart library to draw a pie chart with different options.

Here we will first collect the data from MySQL table by using Php data object ( PDO ) , inside the zip file which you can download from the above URL you can see pages for mysqli connection and data retrieval.
Data is taken out of MySQL table by using query and executing the same through PDO. After getting the data as an array in PHP the same will be transferred to JavaScript array by using Json function.
After getting the JavaScript array the same will be used to add data to our google chart.

Finally the chart is drawn by using a div tag as explained in the first tutorial. We can change the options to customize the chart based on our requirements.
We can use Bar Chart or Column Chart by using the appropriate google chart method.
By using options isStacked true we can change the chart to stacked graph.
