Enable/disable controls in line charts

[Vivek More]

Hi All,

I m trying to do some customization in line charts. I have 3-4 lines in single chart. I want to provide some control to enable/disable (show/hide) these lines individually. Also vAxis should auto scale based on the values of lines visible in charts.

Thanks
Vivek

There are many different ways to do this.  As one example, here's a hack that I wrote that turns a CategoryPicker control into a data series selector: http://jsfiddle.net/asgallant/WaUu2/

I have a customized line chart. I have provided some check box options to hide/show lines in chart (Similar to http://jsfiddle.net/asgallant/WaUu2/)

So when I hide/disable any line, it changes color of other lines, as I am changing the order of other columns. So is there any way by which we can keep the order of columns same, so that it will not change the color of other lines when we hide some lines.

Also is there any way to get change in scale(vAxis.max value) when we enable/disable lines

If you want the colors to remain consistent, you have to track which data series you are showing in the chart, and assign colors to them manually (using the series.<series index>.color option).  Similarly, you can change the vAxis.max option when you change series.
