Thanks Vishwas,

This is what I want in my chart what you are showing in jsfiddle, I am taking data from Database and my ques are,
How should I take start and end value?
How should I calculate Y=mx + b for Trendline Calculation. I only have x Value. How do I calculate m and b value.Or is there any way to calculate trend line from database value.each time data will vary, sometimes I get 5 rows, Sometimes I get 10 row for chart. in that case how do I calculate Trendline.
I have have some code but I can’t paste here as it is long. How do I show you my code. In jsfiddle it will not work because databae is not there. Please help.

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.

One More Question: yValue += Math.round(Math.random() * 10 – 5); What is 10 and 5 here? What we are doing in this formula. Sorry I am new to this.

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
