@tnt,

In JavaScript Month starts from 0 (January) and ends at 11(December). So in your case, new Date(2020, 01, 30) and new Date(2020, 01, 31) represents 1st of March and 2nd March respectively. Changing new Date(2020, 01, 30) to new Date(2020, 00, 30) and new Date(2020, 01, 31) to new Date(2020, 00, 31) should work fine in your case.

@utsavgupta,

You can achieve your requirement with the help of stripLines on axisX as shown in this JSFiddle.

Thanks for your suggestion. We will further improve this behaviour in future releases.

@mportillo,

It seems to be working fine. Can you kindly create a sample project reproducing the issue and share it with us over Google-Drive or Onedrive so that we can look into your code, understand the scenario better and help you out?

Larry, @elbit12,

The behavior is by design so that zooming is limited upto a certain region, so that user doesn’t end up zooming into a blank-region (region with no dataPoints). To zoom into a certain region, there should be a minimum of 3-4 dataPoints over the axis.

When zoomType is either set to ‘x’ or ‘y’, it checks for number of datapoints over specific axis. But when zoomType is ‘xy’ it checks for the datapoints within the selected region over both the axes because of which it gets invalidated in certain cases. We will reconsider and improve this behavior in future releases.

@joran,

Earlier WebKit allowed 448MB of canvas buffer memory whereas now they have dropped it to 224MB. Because of this, there was some memory issue with CanvasJS Charts in the latest iOS. However, we had optimized memory consumption in CanvasJS v2.3 – please check out this release blog for more info.

Also, we will further optimize it in future releases.

@uzair,

Please take a look at this gallery page for an example on creating dynamic chart in PHP.

Considering this thread as duplicate of want to show the weekly Dynamically date using php on X Axis? and hence closing the same.

If this doesn’t solve your requirements, kindly create a sample project along with sample data and share it to us over Google-Drive or Onedive so that we can look into your code, understand the scenario better and help you out.

@utsavgupta,

Setting minimum of axisY to a negative should work fine in your case as shown in this JSFiddle.

@interactivejam,

Whenever there is less number of dataPoint with labels, there is no necessity of setting the interval as chart handles it automatically. So, removing the interval should work fine in your case.

@vishnu-penubelli,

Whenever dataSeries are hidden, you can hide its information from toolTip with the help of toolTipContent as shown in this JSFiddle.

@ctapan,

You need to include library once in a page and can render as many charts as you need. Please take a look at this documentation page for step to step tutorial on rendering multiple charts in a single page.

@vishnu-penubelli,

Chart elements may look blur when either zoom within display setting of browser or windows is changed. Resetting zoom to 100% should work fine in this case.

If the issue still persists, kindly create JSFiddle reproducing the issue you are facing and share it with us so that we can look into your code, understand the scenario better and help you out.
