Re: how to disable tooltip for 'select' event on column chart ?

[asgallant]

Setting the tooltip.trigger option to 'none' should work.

Changing bar color on select is a bit trickier to do, and requires some hackery to make it work.  I have example code here that you can use.

You need to load the "corechart" package, not the "columnchart" package.  This:

google.load("visualization", "1",{packages:["columnchart"],"callback" : initialize});

should be this:

google.load("visualization", "1",{packages:["corechart"],"callback" : initialize});

If i use 'corechart' google elevation service is not showing properly

please see the attached file for full details. 

with the example provided to change the bar colors on 'selection' it is automatically converting to the corechart from columnchart. 

please suggest me a way to resolve the issues.

Thank you for your response

You can change the axis range by setting the vAxis.minValue and vAxis.maxValue options.  The API can (and often times does) override those values to make the axis "neater", so if you end up with values that you don't want, then you can set the vAxis.viewWindow.min and vAxis.viewWindow.max options, which lock the minimum and maximum axis values to exactly what you specify, regardless of the values of your data.
