Question

I want to know that how can i get the max, min, avg and current value of any multi series chart whenever user zoomed in or zoomed out. chart has “x” as timestamp and “y” as value. And here is my code for single chart. hope you would understand.

@paulfansare,

The method that calculates the minimum, maximum and other parameters is called only on rangeChanged event because of which table is populated only when you zoom/pan or reset the chart. To populate the table soon after rendering the chart, you need to call the method soon after chart.render().
chart.render();
showTableData(chart);

Please take a look at this Updated JSFiddle.

@Vishwas R Thanks for your help. It worked for me and i am very happy with your solution. Just one thing i need in that graph.
Your given js fiddle works only when we drag reset or zoom in. But it doesn't work when it loads. In other words i want that if a graph is loaded the table should automatically show their respective series data (while i call with ajax it should work too). if user do any actions on graph like drag or anything else than your function would work. Can you tell me that how can achieve that.

@paulfansare,

The link that you have shared seems to be working fine.

The JSFiddle that was shared earlier was adding 3 rows to the table which can be made generic to add number of rows based on number of dataSeries as shown in this updated JSFiddle.

@Vishwas_R, your jsfiddle https://jsfiddle.net/canvasjs/k3wyfv2c/ is working fine enough, but it messed up when you change data series using ajax call.
here is an expamle please check this website. http://www.coinproof.co/feature-4/
Here i am using your js fiddle. it works nice if i use it for only 3 multiple data-series but if i use it for more than 3 it all get messed up and cannot work either.
