## FusionCharts PHP Class API > First Chart

For a start, let's create a simple chart that will visually depict the Weekly Sales of a fictitious shop. The sample data that we intend to plot can be tabularized as under:

Week | Previous Month (sales)
Week 1 | $40800
Week 2 | $31400
Week 3 | $26700
Week 4 | $54400

Let's see how to use FusionCharts PHP Class to plot this data into a column3D chart:
<?php # Include FusionCharts PHP Class include('../Class/FusionCharts_Gen.php'); # Create Column3D chart Object $FC = new FusionCharts("Column3D","300","250");
# set the relative path of the swf file
$FC->setSWFPath("../FusionCharts/");
# Set chart attributes
$strParam="caption=Weekly Sales;xAxisName=Week;yAxisName=Revenue;numberPrefix=$;decimalPrecision=0;formatNumberScale=1";
$FC->setChartParams($strParam);
# add chart values and category names
$FC->addChartData("40800","name=Week 1");
$FC->addChartData("31400","name=Week 2");
$FC->addChartData("26700","name=Week 3");
$FC->addChartData("54400","name=Week 4");

?>

<title>First Chart Using FusionCharts PHP Class</title>
<script language='javascript' src='../FusionCharts/FusionCharts.js'></script>
</head>
<body>

<?
# Render Chart
$FC->renderChart();
?>

</body>
</html>

Let's analyze the steps involved in the above code:

- We include FusionCharts_Gen.php in the program. This file contains FusionCharts PHP Class codes.
  include('../Class/FusionCharts_Gen.php');
- We create a Column3D chart object.
  $FC = new FusionCharts("Column3D","300","250");
  The constructor of FusionCharts PHP Class is invoked and it initializes chart type, chart width and chart height properties of the object.
- Next, we set relative path to the chart SWF files using setSwfPath() function. This is the path from which we load the chart SWF files.
  $FC->setSWFPath("../FusionCharts/");
- We store all desired chart attributes in the $strParam variable and set chart attributes using setChartParams() function.
  $FC->setChartParams($strParam);
- Now, we provide chart data with addChartData() function.We pass the value first and then the category name against each value as a parameter i.e., name=Week 1 etc.
  $FC->addChartData("40800","name=Week 1");
  $FC->addChartData("31400","name=Week 2");
  $FC->addChartData("26700","name=Week 3");
  $FC->addChartData("54400","name=Week 4");
- Finally, we include FusionCharts.js - FusionCharts JavaScript Embedding Class.
- And display the chart using renderChart() function.
  $FC->renderChart();

Here is the Column 3D chart that our FusionCharts PHP Class renders:
Please go through FusionCharts PHP Class API Reference section to know more about the functions used in the above code.
How to change chart width and chart height?
When we declare an object of FusionCharts PHP Class the constructor is invoked. This constructor accepts the parameters that sets the chart type, chart width and height. In the code above the statement $FC = new FusionCharts("Column3D","300","250"); invokes the constructor which sets chart type as Column3D; width to 300 pixels and height to 250 pixels.
Hence we can use this to set the desired dimension of our charts. Let's set our chart's dimension to 450 x 350 pixels.

$FC = new FusionCharts("Column3D","450","350");
How to change chart type?
As we discussed above chart type is also determined while declaring FusionCharts PHP Class object. $FC = new FusionCharts("Column3D","300","250"); To make a Pie Chart for our Weekly Revenue data, we have to use the following specification while creating FusionCharts class object:
$FC = new FusionCharts("Pie3D","300","250");
To change chart type you can use any of the Chart Type names listed below :

Chart Type | Description
Column2D | Single Series Column 2D Chart
Column3D | Single Series Column 3D Chart
Line | Single Series Line Chart
Pie3D | Single Series Pie 3D Chart
Pie2D | Single Series Pie 2D Chart
Bar2D | Single Series Bar 2D Chart
Area2D | Single Series Area 2D Chart
Doughnut2D | Single Series Doughnut 2D Chart
MSColumn3D | Multi-Series Column 3D Chart
MSColumn2D | Multi-Series Column 2D Chart
MSArea2D | Multi-Series Column 2D Chart
MSLine | Multi-Series Line Chart
MSBar2D | Multi-Series Bar Chart
StackedColumn2D | Stacked Column 2D Chart
StackedColumn3D | Stacked Column 3D Chart
StackedBar2D | Stacked Bar 2D Chart
StackedArea2D | Stacked Area 2D Chart
MSColumn3DLineDY | Combination Dual Y Chart (Column 3D + Line)
MSColumn2DLineDY | Combination Dual Y Chart (Column 2D + Line)
