[SalesForce] how to pass operators dynamically to if condition

enter image description here

I am trying to implement multiple filters on visual force page to generate custom reports by using external system data from rest call.I am not going to store anything in salesforce objects.So i have to do search by looping throught data

if(searchField1=searchVal1 && searchField2=searchVal2 || searchField3=searchVal3)){
    system.debug('***'+criteria matched);
}

but the problem is i have to change the && and || operators according to user selection from drop-down like if user selects OR and And in dropdown it has to chnage as

if(searchField1=searchVal1 || searchField2=searchVal2 && searchField3=searchVal3)){
    system.debug('***'+criteria matched);
}

so i was wondering is there any way to achieve this dynamically…

if(searchField1=searchVal1 'operator1' searchField2=searchVal2 'operator2' searchField3=searchVal3)){
        system.debug('***'+criteria matched);
    }

happy to hear any changes in the code…

Ignoring the issue mention in the comment, you can create methods that allow this sort of code:

if (op(searchField1 == searchVal1, operator1, searchField2 == searchVal2) ...

where the method would be:

private Boolean op(Boolean b1, String operator, Boolean b2) {
    return operator == 'and' ? (b1 && b2) : (b1 || b2);
}

[SalesForce] Dynamically pass values for multiple charts in diiferent tabs

Below is some code that I posted as an answer to this Salesforce Visualforce Bar Chart problem question that uses the "controller method reference" data option. For naming you are using in your Visualforce, in the class change v to data and n to name.

To support multiple charts, you would need to add multiple methods that return different data.

<apex:page controller="ChartController">
    <apex:pageBlock title="Annual Recurring Revenue">
        <apex:chart name="AnnualRecurringRevenue" data="{!nvs}" width="400" height="400"
                colorSet="#156F9E,#FF9123,#6BAE4A,#424242,#A4A4A4">
            <apex:axis type="Numeric" position="left" grid="true" title="$(Millions)"
                    fields="v"/>
            <apex:axis type="Category" position="bottom" grid="false" title="Quarter"
                    fields="n"/>
            <apex:barSeries orientation="vertical" axis="left" xField="n" yField="v"
                    colorsProgressWithinSeries="true"/>
        </apex:chart>
    </apex:pageBlock>
</apex:page>

public class ChartController {
    public class Nv {
        public String n { get; private set; }        
        public Decimal v { get; private set; }
        Nv(String n, Decimal v) {
            this.n = n;
            this.v = v;       
        }
    }
    public Nv[] getNvs() {
        return new Nv[] {
            new Nv('Actual', 106.00),
            new Nv('Forecast', 150.56),
            new Nv('Plan', 135.00),
            new Nv('Prior Qtr', 97.00),
            new Nv('Prior Yr', 88.44)
        };
    }
}

In Controller use this code:
