# How to plot this spectrum? [closed]

Please, I want to know which code to use to plot a spectrum like this.

Need examples for more details please.

• Try DensityPlot or ListDensityPlot with option ColorFunction -> "Rainbow". – Henrik Schumacher Sep 3 '18 at 21:07
• This looks like measurement data stored in arrays. So ListDensityPlot might be the better choice. – Henrik Schumacher Sep 3 '18 at 21:17
