History

ColdFusion 10: Added the following attributes: {{alpha, animate, aspect, background, bevel, border, marker, color, label, hoverMarker, data, scales, shadow, tooltip, zcolumn}}ColdFusion MX 7:

  • Added the dataLabelStyle attribute.
  • Added the horizontalbar value of the type attribute.
    ColdFusion MX 6.1: Changed interpolation behavior: the tag now interpolates data points on line charts with multiple series.ColdFusion MX: Added this tag.

Usage

The following attributes are not supported for Client side charting:paintStyle and the following values for markerstyle: letterx, mcross, snow, and rcross.A new attribute zvalue added to cfchartdata: Applicable if chart takes a third dimension in addition to x and y.
For a pie chart, ColdFusion sets pie slice colors as follows:

  • If the seriesColor attribute is omitted, ColdFusion automatically determines the colors of the slices.
  • If the seriesColor attribute is specified, ColdFusion automatically determines the colors of the slices after the first one, starting with the specified color for the first slice.

Limitations

The following server-side charting features are not available with client-side charting:

  • Linking charts to URL
  • Writing charts to a variable

Example 1

<!--- The following example analyzes the salary data in the cfdocexamples 
database and generates a bar chart showing average salary by department. ---> 

<!--- Get the raw data from the database. ---> 
<cfquery name="GetSalaries" datasource="cfdocexamples"> 
SELECT Departmt.Dept_Name, 
Employee.Dept_ID, 
Employee.Salary 
FROM Departmt, Employee 
WHERE Departmt.Dept_ID = Employee.Dept_ID 
</cfquery> 

<!--- Use a query of queries to generate a new query with ---> 
<!--- statistical data for each department. ---> 
<!--- AVG and SUM calculate statistics. ---> 
<!--- GROUP BY generates results for each department. ---> 
<cfquery dbtype = "query" name = "DataTable"> 
SELECT 
Dept_Name, 
AVG(Salary) AS avgSal, 
SUM(Salary) AS sumSal 
FROM GetSalaries 
GROUP BY Dept_Name 
</cfquery> 

<!--- Reformat the generated numbers to show only thousands. ---> 
<cfloop index = "i" from = "1" to = "#DataTable.RecordCount#"> 
<cfset DataTable.sumSal[i] = Round(DataTable.sumSal[i]/1000)*1000> 
<cfset DataTable.avgSal[i] = Round(DataTable.avgSal[i]/1000)*1000> 
</cfloop> 

<h1>Employee Salary Analysis</h1> 
<!--- Bar graph, from Query of Queries ---> 
<cfchart format="flash" 
xaxistitle="Department" 
yaxistitle="Salary Average"> 

<cfchartseries type="bar" 
query="DataTable" 
itemcolumn="Dept_Name" 
valuecolumn="avgSal" /> 
</cfchart>

Example 2

The following is a basic example of using client side charting.

<cfchart format ="html" type="pie"> 
<cfchartseries> 
<cfchartdata item="New car sales" value="50000"> 
<cfchartdata item="Used car sales" value="25000"> 
<cfchartdata item="Leasing" value="30000"> 
<cfchartdata item="Service" value="40000"> 
</cfchartseries> 
</cfchart>

Example 3

This example showcases how you can create a simple bubble chart by specifying zcolumn.

<cfchart format ="html" type="bubble" query="ChartQuery" showlegend="false"> 
<cfchartseries query="ProdQuery" type="bubble" itemcolumn="title" valuecolumn="total_days" zcolumn="rem_days" label="Total_Days"> 
</cfchart>

Example 4

This is an example that specifies labels as a struct.

<cfchart format ="html" type="bubble" que ry = " ChartQ ue ry " showlegend="false" labels=#[{"text"="Hello Label","hook":"node:plot=0,index=2,offset-x=-10,offset-y=-90"}]#> 
<cfchartseries type="bubble" label="Total_Days"> 
<cfchartdata item=1 value=10 zvalue=40> 
<cfchartdata item=2 value=20 zvalue=30> 
<cfchartdata item=3 value=30 zvalue=20> 
<cfchartdata item=4 value=20 zvalue=35> 
<cfchartdata item=5 value=40 zvalue=10> 
</cfchartseries> 
</cfchart>
