We have 2 Y-axis on the same chart and we need to force the 0s lined up for these two Y-axis. What's the best way to do this?
Take a look the attached png file, you can see two Y-axis have 0 at different levels.

Hello Jason Xiao,
RadChart will not align the two Y axes automatically, so you will need to set their AutoRange properties to false and configure their range, so that the zeroes are aligned. Here is an example:
RadChart1.DefaultView.ChartArea.AxisY.AutoRange = false;
RadChart1.DefaultView.ChartArea.AdditionalYAxes[0].AutoRange = false;
RadChart1.DefaultView.ChartArea.AxisY.AddRange(-10, 35, 5);
RadChart1.DefaultView.ChartArea.AdditionalYAxes[0].AddRange(-400, 1400, 200);
That is -- the additional Y axis' min, max and step are 40 times their counterparts in the main one.
Kind regards,

Good afternoon Ves
I am having a similar problem using a second Y Axis. See attached image...
Note that the tool tip for the line series is showing $0 which is the correct amount for that time point afetr the payment of $178.09 dollars has occurred as seen in the 'Payment Schedule' seen to the right in the picture.
The chart is declared in the XAML as follows:
And populated by code as follows:
Note that I am trying to have both Y-Axes have $0 as their starting minimum value. It would seem that the values on the chart are correct when checked by showing the tooltips for the datapoints but the additional Y-Axis (on the right) ends up with the wrong values.
Any thoughts on what I am doing wrong would be most appreciated.

Hello Ralph,
Thanks for the details. I was able to reproduce the issue. I have logged it in our public issue tracking system, you can find it here. The fix will be available in one of the next internal builds and in the next official version -- Q3 2010. I have updated your Telerik points.

I have this exact problem. The proposed solution does work, but in my situation the calculations are anything but trivial. Is the solution that was posted in 2010 still my only option five years later? I have spent hours and hours and hours trying to solve this issue.

Hi Stephanie,
We do not have this range-sync feature in neither of our charts (nor the old RadChart, nor the new ChartView). You need to set a manual range for at least one of the axes, may be both.
