yValue += Math.round(Math.random() * 10 – 5);

What is 10 and 5 here. On what basis we take 10 and 5. Are they constant values? in any chart we are going to take 10 , 5 or it depends on X and Y value. Please explain this also.

How can we display exact decimal in Moving Average Calculation. Currently it is showing either .50 or 1. How can I show exact calculation like 1.82 if my calculation is 1.82 in moving average Tool Tip.

Also, How can I set left hand side Label point starting 0, 0.2, 0.4,0.6,0.8,1.0,1.2 etc. Normally it comes automatically but is there way to set it by code.

Please help
