chart-line looks more like a river than a Line Chart

This could be just me. Honestly, I find it hard to recognize the chart-line icon. When I use it, it looks more like a river than a Line Chart. Due to that, I end up using the chart-bar instead to go beside the "Analytics" or "Reports" link texts.

If I may, I'd suggest using only a single line waving upwards and inside an X and Y plane. It's Font-Awesome equivalent is more recognizable to me.

Just my thoughts :)
