Data for this line chart is built by rgraph's utility function "getDataviaFormula". This function takes a formula as input and calculates y-values based on provided start x-value, x-steps (intervals) and a maximum x-value. The number of iterations is limited to 500. The calculation finishes when either maximum of x-values or maximum of iteration is reached.
Important: Because rgraph uses as delimiter curly brackets ("{" "}") you must recode the draw_option parameter from "trace( { frames: 60 } );" to "trace2( [ frames: 60 ] );" (use square brackets instead). If you do not change accordingly the chart will not display.
