x axis range

[Matt]

I'm plotting bucketed data that looks like a bell curve. Works just
fine; who doesn't love bell curves? With bell curve data, outlier
data on either side can make the graph look less 'pretty'. I;ve been
pouring over the Configuration Options here:
http://code.google.com/apis/chart/interactive/docs/gallery/areachart.html

My question: Is there a way to adjust the range of the x axis .....
say, give a max and min? I know I could just send fewer rows to the
graph, but that will be a pain with the data I have.

in regard to xAxis, there is no min/max value. however, you can use the NumberRangeFilter.

here is a small sample that you can play with: http://code.google.com/apis/ajax/playground/?type=visualization#numberrangefilter_control

You can create a DataView from the DataTable, use the DataView#hideRows() method to hide your outliers, and then draw the chart from the view.  Eg: 

/*  assumes:
 *    data is a DataTable object
 *    chart is a chart object
 *    options is an option object to pass to the chart
 */
var view = new google.visualizations.DataView(data);
// hide the first 3 and last 3 points (outliers)
view.hideRows(0, 2);
view.hideRows(data.getNumberOfRows() - 3, data.getNumberOfRows() - 1);
chart.draw(view, options);

Roni and asgallant, thank you for the comments. I like the slider
idea, I am going to give that a try and followup. Should work well for
the user as he/she should be able to clip data at both ends with just
two slides.

The one big hangup is that my AreaChart demands the first column
(xaxis) be a string, while the control filter expects to see numeric
values because I am using the number filter:
'controlType': 'NumberRangeFilter',

[Jinji]

This is still undocumented, but you can specify strictFirstColumnType: true in the options (this will be the default in just a couple of months), and then have an AreaChart with numbers in first column. After you do that, you can use hAxis.viewWindow in a similar way to vAxis.viewWindow.

Hope this helps.

Filter on the data column, not the axis column.

Jinji, thank you for uncovering something not in the doc. I got my
solution working, utilizing asgallant's recommendation for using a
DataView that hides columns when a user enters a min and max that they
choose. Version 2 may eventually use the strictFirstColumnType with
the Dashboard. So I will have used a touch of everyone's solution,
thanks all!
