Customize tooltip text of line chart series point

[Quest Resource Management]

Hello,

I have a json data format as below:

• xField: [5,7,9,7,1]
• yField: [1,5,9,8,6]
• Tooltip: ["A","B","C","D","E"]

This data is to be displayed Kendo UI Line Chart. I am able to plot line chart using xField and yField values.

But I am unable to customize the tooltip text (it is showing either xField or yField). I referred documentation but cannot find way to achieve this.

Is there any way to provide different/customize value in tooltip as well as data label?

Please assist me on this.

Thanks

Hi Eric,

You can customize the text displayed in the Chart's tooltip using tooltip template. For a working example please check this online demo.

Hello Iliana,

Thanks for your reply.

But I wanted to show tooltip from different JSON array, as explained in first sample data.

My category is - xField: [5,7,9,7,1]
My series is - yField: [1,5,9,8,6]
My tooltip will be shown from - density: ["A","B","C","D","E"]

Now I am supposed to display the values of Density in tooltip of series (dynamically).

Thanks

Hello Eric,

First of all, let me apologize for the misunderstanding. I am afraid what you would like to achieve is not supported in Kendo UI Chart and its implementation requires additional code. As a possible approach I can suggest hooking up to the DataSource schema' s parse() method, loop through both JSON arrays and pass the "density" field to the first JSON.
