First of all, I would like to appreciate Telerik Team for supporting our critical requirement development.

  OK Coming to point.

I have to display some XY axis radchart to the user.
X-Axis values varies between -400 and +400 Or -1 and +1 (depends on data coming this X-axis value might varies)
Y-Axis values varies between 1 and +1000 (depends on data coming this X-axis value might varies)

Once user click on btnGetChartResult then I would like to show overview of the chart as attached (chart view issue due to number of x-axis scale points.png), In this chart let assume I have X-axis points from -400 to +400 (critical scenario)

If the User wants to see each and every X-axis point with their Y-axis aligned data, Then I would like to give a Zoom in option to see, Then the screen should looks like as attached(chart view issue due to number of x-axis scale points1.png).

Issue we are having with below code, If the user click on btnGetChartResult then the results are as attached(Chart display for on one 1Xaxis point.png).

Issue 1.If the chart has only 1 x-axis for whole chart, its showing zoomed view with scroll option.
Issue 2.Even If the chart has the points between -400 and +400, firstly I would like to show the chart without zoom, if the user wants, he can zoom-in the chart.
Issue 3.Even If am working with below code, sometimes it is showing various behavior in showing the data on chart, to get perfect results some times we are refreshing the chart by clicking on btnGetChartResult,

Please let me know, Where am making mistakes.
Your Help is greatly appreciated!

Thank You Very Much Telerik Team.

Hi Staish,

Onto your questions:
1) - RadChart supports only a single X axis, so I am not sure about this condition in the question. Still, looking at the code I can see RadChart.ClientSettings.XScale = 10 -- this defines the chart as being 10x zoomed along X axis and it would be expected to display scrollbars for controlling this.
2) - Same as above -- you can remove the XScale setting, so the chart will appear initially with no zoom.
3) - I am not sure I followed this one. Your code does not include the button in question, so I am not aware of the action taken and what data is sent to RadChart. Can you provide more details about the various behaviors you see, as well as the specific configuration and the expected result. Thank you.

Best regards,
Ves
