I have a table of temperatures. Records in my table has datetime field, which is not filled with continuously data (every 10 minutes), but every 5 minutes if there is a change in temperature. So new record can appear after 1 hour.
I choose scatter graph for this task, but unfortunately I discovered that scatter does not support selection, which is critical for me.
I also notice a post on feedback page, but honestly the feature will never be implemented if you will wait for enough user response.

Don't know why scatter doesn't implement selection, but what can I do. Can I chose a different graph with data I have?

Hi Matjaz,

You can achieve similar functionality with a line chart with no line between points. I hope that this can help you: http://dojo.telerik.com/@germanov/OQUgI/2

Very close. Thank you.
I mean something like this.

I have one problem:
how can I lose points (want only line)
and one question:
documentation says "The Scatter and Scatter Line series are suitable for plotting two-dimensional data.Each data point is an array that contains two values - X and Y." So this is true, but apparently you can have a 2 dimensional data also with line (in your modified dojo). 
Then what is the difference?

Hello Matjaz,

With series.markers.visible: false you can prevent markers rendering.

The major difference is the axis. If you have categoryAxis you will be not able to do this: http://dojo.telerik.com/@germanov/UkAzE

The categoryAxis will not allow you to draw two points for a single category and series. In this case the categoryAxis will aggregate this points.
