In my new demo project, I need to draw Area Chart with CFChart for letting know the process rate of data. My boss told me to draw the Area Chart in Coldfusion like that.

As far as I know, CFChart support only single bar in Area Chart type. That's why I was supposed to complaint him that's not possible to draw such area chart style in Coldfusion. But I may need to google it before complaining. Unfortunately, no CF resources sites show how to draw multiple bar in Area Chart and they only recommend to use Line Chart instead of Area Chart for drawing multiple line.

Fortunately, CF Docs show how to draw Area Chart with CFChart as follow.

view plain print about
1<cfchart
2    chartheight="200"
3    chartwidth="300"
4    xaxistitle="Year (Age)"
5    yaxistitle="Data"
6    format="png">
7    
8    <cfchartseries type="area">
9        <cfchartdata item="10" value="40">
10        <cfchartdata item="20" value="50">
11    </cfchartseries>
12</cfchart>

After rendering above coding, the result will be as follow.

You will see only single orange bar is displaying in above chart. What we gonna do if we want for displaying multiple bar in above chart?

What I get is to create another chartseries within in CFChart for another area bar in Coldfusion.

view plain print about
1<cfchart
2    chartheight="200"
3    chartwidth="300"
4    xaxistitle="Year"
5    yaxistitle="Month"
6    format="png">
7    <cfchartseries type="area">
8        <cfchartdata item="10" value="40">
9        <cfchartdata item="20" value="50">
10    </cfchartseries>
11    <cfchartseries type="area">
12        <cfchartdata item="30" value="80">
13        <cfchartdata item="40" value="90">
14    </cfchartseries>    
15</cfchart>

After rendering, the outcome will be as follow.
