@jameela,

Can you kindly create JSFiddle reproducing the issue you are facing and share it with us so that we can look into the code, understand the scenario better and help you out?

Hii in line graph iam giving x axis values randomly like this
{x:43, y:54}
{x:0, y:23}
{x:24, y:14}
{x:12, y:44}
{x:54, y:14}
but it is not plotting in linear order

when we give x axis values in increasing order like this
{x:10, y:54}
{x:20, y:23}
{x:30, y:14}
{x:40, y:44}
{x:50, y:14} then only it is plotting correctly.
can u plz tell me how to solve this.

@jameela,

CanvasJS just renders the dataPoints in the order passed by you, it doesn’t sort the dataPoints. However with few lines of code, you can sort dataPoints to render chart with linear order of x as shown in this JSFiddle.

In line graph i want zoom particular area

for ex: i want to see the values between 1 to 1000
can you please suggest how to do this
in this line graph iam reading data from csv file

And one more query how to handle huge data like by days or weeks.

@jameela,

You can programmatically zoom / pan to a region by setting viewportMinimum and viewportMaximum.

And one more query how to handle huge data like by days or weeks.

Can you kindly brief us more about your requirement along with some example or pictorial representation so that we can understand the scenario better and help you out?
