I need to get a chart like this:
I find this example but it uses old version of ChartJs. I try it using v2.0 but I don't get it.
Can someone post a example?

Bar chart Bar charts are created by setting type to bar (to flip the direction of the bars, set type to horizontalBar ). The colors of the bars are set by passing one color to backgroundColor (all bars will have the same color), or an array of colors.
Select the data that you want to display in the form of a chart. In the Insert tab, click Column Charts (in Charts section) and select “2-D stacked bar.” A chart appears, as shown in the following image. The stacked bar chart compares the sales revenue generated in different months with respect to time.
Define a matrix of size 4 X 3 whose rows will be used as bars, i.e, each row of the matrix will be represented as a bar in the stacked graph. Pass this array and matrix as inputs to the 'Bar' function. Pass 'stacked' as third argument. This argument represents that the we need a stacked bar graph as the output.
With v2.1.x, you can achieve this using the stacked option
...
options: {
scales:{
xAxes: [{
stacked: true
}],
yAxes: [{
stacked: true
}]
}
}

<canvas id="myChart"></canvas>After fiddling forever, I finally got it to work, here's a sample. Somebody please update the docs!
