This is the Średnia wartość icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
This icon shows a graph with a normal "L" shaped line. On the graph there is a large curve which starts the graph at the very bottom, peaks at the top of the graph, then curves back down to the bottom. In the center, running horizontally, there is a dotted line to indicate the average value.
