1)Merged the update charts functionality in initscatterchart function

2)Implemented the dynamic axis params,while initializing the charts we need the pass the parameters that required to display in and X and Y axis eg:

xAxisParams:[{lbl:'CPU (%)',key:'cpu',type:'float'},{lbl:'Instances',key:'instCnt'}]}};
Parameters are
"lbl" -  value displayed in the drop down
"key" -  key is used the look in the chart data
"type" - type of the value,if it is not present it will considered as the Integer
