Dynamic Chart Filtering

Dynamic Chart Filtering

 Hello.

I look at the post here:

http://blogs.zoho.com/general/dynamic-chart-filtering-and-url-data-type-in-zoho-reports

The Dynamic Chart Filtering is exactly what I need for my chart.

I have 3 Columns:

1. The X-Axis - Series of number 1 Through 145.

2. Y-Axis - Data (Integer number according to the X Series).

3. Y-Axis - Data (Integer number according to the X Series).

I create a Line Chart out of them yet can't enable those Checkboxes feature.

How do I enable it?

The Chart can accessed heres:

Thanks.
