Eesger,

As of now we don’t have this feature. But you can work around by setting fillOpacity to 0.7 or 0.8 to make gridlines visible through dataPoints. Check this jsfiddle.

Another option is to place stripLines with showOnTop set to true, so that lines are shown on top of data. Check this jsfiddle.

Navinder,

As of now we don’t have 3D support in charts

[Vishwas R]

Chandru,

Please check this jsfiddle.

Parthu,

Check this jsfiddle.

Prasanth,

You can use JavaScript eval() function to evaluate an expression. According to user input expression generate dataPoints and render chart. Here is an example.

[Vishwas R]

Prasanth,

You can store all generated dataPoints, according to equation, in an array and assign it to chart dataPoints. Here is an example.

Eshwar,

toolTip, click events are applied even to dataPoint with zero y-value. Here is the updated fiddle.

Jenilkanani,

If y-value is zero, when you mouse-hover the axisX line at the corresponding x-value toolTip will be shown. Check the screenshot below. If the y-value (zero) is not present in first dataSeries, you can set toolTip.shared to true to show the zero value in toolTip.

If this doesn’t solve your requirement, kindly create a jsfiddle, so that we can look into your requirement properly and help you out.

Wazabe,

You can use stripLines to achieve this. Check this example.

Stefanaki,

Its not bug, we observed that the x-value you are providing is not in JavaScript Date-Time string format. Please refer to this link for JavaScript Date-Time String Formats. And here is the working fiddle.

Check the screenshots of working fiddle browsed in IE and Firefox.

Alex,

Yes Multiple Y-axis is on our roadmap. And will be released in September.

Xiaosongzou,

Thanks for reporting. We will look into the issue and get back to you at the earliest.

The issue is with the css-styling. Instead of using float:left, you can use display: inline-block. Check this example.

[UPDATE]
We’ve fixed this issue in the latest build. Please, do download the latest version and let us know your feedback.

Whenever you move finger / pointer on the chart, the chart has to know if you are trying to scroll or interact with the chart. Hence we have implemented a behavior where if you hold the finger for a while on the chart, it captures the event and doesn’t scroll. On the other hand, if you move pointer / finger quickly without pausing, it allows you to scroll. Can you try as mentioned above and let us know?

Also, can you please let us know your Device Model, OS, and Browser Version?
