Hello,

I like to add a black background to my below code and the chart lines in white, how do i achieve it ?

plot({ data: [ 3, 1, 2, 3, 4 ], filename: 'output2.png', style: 'linespoints', title: 'Example 'Title', \n runs onto multiple lines', logscale: true, xlabel: 'time', ylabel: 'length of string', format: 'png' });

Kindly advice.
