By default, chart colors match those of the built-in reporting and analytics charts so that you can create visually-consistent dashboards. If you want to create your own color scheme you can customize the colors of most chart elements.

To provide a set of color definitions to draw data series elements (bars, pie wedges, and so on), use the colorSet attribute. Set <apex:chart colorSet=”…”> to specify the colors to be used for every data series in a chart. Set colorSet on a data series component to specify colors for that series only.

Sample Code:


Visualforce Page:


<apex:page controller=”Sample”>
    <apex:pageblock title=”Members and their Years of experience” >
        <apex:chart height=”250″ width=”350″ data=”{!pieData}”> 
            <apex:pieSeries tips=”true” dataField=”data” labelField=”name” colorSet=”#37241E,#94B3C8,#4D4E24,#BD8025,#816A4A,#F0E68C”/> 
            <apex:legend position=”bottom”/>
        </apex:chart>
    </apex:pageblock>
                        
    <apex:pageblock title=”Members and their Years of experience” >
        <apex:chart height=”250″ width=”350″ data=”{!pieData}”> 
            <apex:axis type=”Numeric” position=”left” fields=”data” title=”Years of experience”/>    
            <apex:axis type=”Category” position=”bottom” fields=”name” title=”Member”/>            
            <apex:barSeries orientation=”vertical” axis=”left” xField=”name” yField=”data” colorSet=”red”/> 
        </apex:chart>
    </apex:pageblock>   

</apex:page>


Apex Controller:


public with sharing class Sample {  
    public List<PieWedgeData> getPieData() {  
        List<PieWedgeData> data = new List<PieWedgeData>();
        List<Member__c> memb = new List<Member__c>();  
        
        String sql = ‘SELECT Name, Year_s_Of_Experience__c FROM Member__c’;
        memb = Database.Query(sql);
        for(Member__c temp:memb)
        {           
            data.add(new PieWedgeData(temp.Name,temp.Year_s_Of_Experience__c));
        }
        return data;  
    }  
    
    // Wrapper class  
    public class PieWedgeData 
    {  
        public String name { get; set; }  
        public Decimal data { get; set; }  
        
        public PieWedgeData(String name, Decimal data) 
        {  
            this.name = name;  
            this.data = data;  
        }  
    }  

}
