I am trying to set the chart 'height' parameter in code for a multi line chart container.
 
	Using 100% results in a smaller chart than I want, yet setting specific pixels is better.
 
	I want to be able to detect the web browser height in pixels and use a 'height' parameter based on the pixel result.
 
	Can anybody help me with this.
 
	My attempts have resulted in a failure to render the chart. I am a beginner with Javascript.
 
	I have attached a sample file.
