Now lets have a look at the code required to generate the above CFCharts.
<cfchart format=”png” name=”mychart” title=”Fruits Harvest” showlegend=”true”>
<cfchartdata item=”Mangoes Harvest” value=”5000″/>
<cfchartdata item=”Oranges Harvest” value=”4000″/>
<cfchartdata item=”Apples Harvest” value=”3000″/>
<cfchartdata item=”Grapes Harvest” value=”2000”/>
The result of a query may directly be converted to a chart by using the code below. Coldfusion will generate the chart data items on its own from the query
<cfchartseries type=”bar” query=”data” itemcolumn=”name” valuecolumn=”sales”/>
The type attribute of Cfchartseries is the most important among the list. It lets you choose from a wide array of chart types such as bar, line, pyramid, area, horizontalbar, cone, curve, cylinder, step, scatter and pie.
But what really takes the pie is the amount of styling options Coldfusion gives to the developers. Instead of setting each of the attributes, I found an easy way of doing this by modifying the built in style files in the folder cf_root\charting\styles and saving them under a new name to access. The style files are simple XML files and modifying them is really easy. One of the coolest attributes was the “show3D” attribute, which gives the chart a 3D effect. The appearance maybe modified to such extents that people will have a hard time figuring out it is custom generated and not designed by a web designer specifically.
