Method for hiding display of TimeSeries (SOLUTION)

[Chris Kosik]

Noticed there were some older questions regarding chart visibility/ Time-series visibility and workarounds.

Thought I would put my 2-cents in and throw what may be an obvious solution to some out there:

The previously answered solution regarding setting entire chart opacity to 0 to keep data ingesting is basically correct, no changes there.

However, I wanted to toggle the visibility of individual Time Series and you can achieve that by accessing and toggling Time Series disabled boolean.

From the smoothie.js source code:

function TimeSeries(options) {

this.options = Util.extend({}, TimeSeries.defaultOptions, options);

this.disabled = false;

this.clear();

}

Example:

function toggleChnl(channel){

if(channel.disabled == false){

channel.disabled = true;

console.log('turn invisible..');

}

else if(channel.disabled == true){

channel.disabled = false;

console.log('visible..');

}

}

Where channel = Time Series object (I call them channels for sensor streams in a system).

Application applies to a common usage of creating a toggle based legend of lots of Time Series lines.
