Experimental chart: three-parametric column chart

I was experimenting with chart types when I came up with this idea. I looked for a way to visualize timeseries for more than one parameter in a single chart and decided to use both x and y axis, and also the color as an information carrier. To use this chart, copy and paste your data from Excel. The data should be organized in three columns, with our without headers.
