## FusionCharts ASP Class API > First Chart
To begin with, let's create a simple chart that will visually depict the Weekly Sales of a fictitious shop. The sample data we intend to plot can be tabularized as shown below:
Week | Previous Month (sales)
Week 1 | $40800
Week 2 | $31400
Week 3 | $26700
Week 4 | $54400
Let's see how to use FusionCharts ASP Class to plot this data into a column3D chart:
<%@LANGUAGE="VBSCRIPT"%> <% ' Include FusionCharts ASP Class %> <!--#include file="../Class/FusionCharts_Gen.asp"--> <% dim FC ' Create FusionCharts ASP class object set FC = new FusionCharts ' Set chart type to Column3D Call FC.setChartType("Column3D") ' Set chart size Call FC.setSize("300","250") ' Set the relative path of the swf file Call FC.setSWFPath("../FusionCharts/") dim strParam ' Define chart attributes strParam="caption=Weekly Sales;xAxisName=Week;yAxisName=Revenue;numberPrefix=$" ' Set chart attributes Call FC.setChartParams(strParam) ' Add chart values and category names Call FC.addChartData("40800","label=Week 1","") Call FC.addChartData("31400","label=Week 2","") Call FC.addChartData("26700","label=Week 3","") Call FC.addChartData("54400","label=Week 4","") %> <html> <head> <title>First Chart Using FusionCharts ASP Class</title> <script language='javascript' src='../FusionCharts/FusionCharts.js'></script> </head> <body> <% ' Render Chart with JS embedding Method Call FC.renderChart(false) %> </body> </html>
Let's analyze the steps involved in the above code: We include FusionCharts_Gen.asp in the program. This file contains FusionCharts ASP Class codes. <!--#include file="../Class/FusionCharts_Gen.asp"--> We create a chart object. set FC = new FusionCharts We specify the chart type. Call FC.setChartType("Column3D") We specify the size of the chart. Call FC.setSize("300","250") Next, we set a relative path to the chart SWF files using setSwfPath() function. This is the path from which we load the chart SWF files. Call FC.setSWFPath("../FusionCharts/") We store all desired chart attributes in the strParam variable and set chart attributes using setChartParams() function. strParam="caption=Weekly Sales;xAxisName=Week;yAxisName=Revenue;numberPrefix=$" Call FC.setChartParams(strParam); Now, we provide chart data through the addChartData() function.We pass the value first and then the category name against each value as a parameter i.e., label=Week 1 etc. Call FC.addChartData("40800","label=Week 1","") Call FC.addChartData("31400","label=Week 2","") Call FC.addChartData("26700","label=Week 3","") Call FC.addChartData("54400","label=Week 4","") NOTE: ASP does not support the concept of optional parameter. Hence, we need to provide all the parameters. In case you have nothing to pass as a parameter to a function, you need to provide a blank ("") value, as we did here for addChartData(). In the coming pages we will follow this rule as well. Finally, we include FusionCharts.js - FusionCharts JavaScript Embedding Class. And display the chart using renderChart() function. Please note False is passed as a parameter to the renderChart() function. This is done to render the chart using JavaScript embedding method. IF you wish to render the chart using HTML embedding method, you would need to pass True instead. Call FC.renderChart(false)
Here is the Column 3D chart that our FusionCharts ASP Class renders:
Please go through FusionCharts ASP 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 ASP Class, we use initializing functions like setChartType, setSize etc. In the code above, the statement Call FC.setSize("300","250") sets the chart's 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.
Call FC.setSize("450","350")
How to change chart type?
As we discussed above chart type is also specified using setChartType function, while declaring FusionCharts ASP Class object. Call FC.setChartType("Column3D") To make a Pie Chart for our Weekly Revenue data, we just need to provide Pie3D instead of Column3D to setChartType function. Call FC.setChartType("Pie3D")
