This post will talk about conditional colours of bars with below like scenarios.

Sample Scenario : 
Print bar color as red when bar value <=2000
Print bar color as green when bar value >2000 and <10000
Print bar color as black when bar value>=10000

Scenario 2 : 
When representing -Ve values on charts .. this kind of representation is preferable. 

Code is Taken from Reference links :


function changeBars(){
var cccOptions = this.chartDefinition;

// For changing extension points, a little more work is required:
var eps = Dashboards.propertiesArrayToObject(cccOptions.extensionPoints);

// add extension points:
eps.bar_fillStyle = function getColor(){
var val = this.scene.vars.value.value;

if(val > 0 && val <= 5000){
return red;
}
else if(val > 5000 && val <= 50000){
return green;
}
else{
return black;
}
};

// Serialize back eps into cccOptions
cccOptions.extensionPoints = Dashboards.objectToPropertiesArray(eps);
}


NOTE : I have tried directly in Extension points but it did not work. 

Sample output 1 :
