@debasis89,

You can position axisX to top by using secondary axisX instead of primary axisX.

@ajinkamb,

As the difference in the two mentioned dataPoint y-value is large, height of the smaller y-value dataPoint will be negligible and not visible. We will reconsider this behaviour to be improved in future releases. However, you can workaround this behaviour by adding some larger value dataPoint instead of smaller value as shown in this JSFiddle.

@debasis89,

Date Time on axisY is not supported as of now. However, you can achieve your above requirement as shown in this JSFiddle.

@ajinkamb,

Index-labels overlap each other as there would be no space available when the datapoint values are small. It can be avoided to an extent by setting indexLabelFontSize to a smaller value.

@jfranco30,

You can disable interaction with chart like updating toolTip, zooming/panning, mouse-events, etc with the help of interactivityEnabled property. Setting interactivityEnabled to false in smaller screen should work fine in your case. Please take a look at this JSFiddle.

@jfranco30,

Please take a look at this gallery page for an example on adding dataPoints from mysql database in PHP.

If you are still facing issues in integrating kindly share sample project along with sample database over Google-Drive and Onedrive so that we can look into code and understand the scenario better and help you resolve.

@kunal,

To display the image properly on zooming and panning, you can call a function to re-position the image on rangeChanged event.

@sana,

Setting exportEnabled property to true lets you to print or save the chart as an image. You can also print the chart programmatically with the help of the print method. Please refer to the documentation for more customisation options available.

@hecatonchireslm,

Setting minimum and maximum of axisX with an appropriate javascript date object or timestamp as per your data range and dataPoints should work fine in your case.

In case you are still facing the issue, can you kindly create JSFiddle along with sample data and share it so that we can look into the code, understand it better and help you out?

@gentrit,

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.

For more optimization on dynamic charts, update chart options and re-render and don’t instantiate/create new chart on every update.

Also, we will further optimize this behavior in future releases.

@utsavgupta,

You can achieve the above requirement by formatting the labels of axisX2 using labelFormatter.
