The first few lines of my raw data looks like this:

```
0    -4.05291
0    -2.75743
0    -0.374328
1    -23.829
1    -21.5973
1    -21.0714

```

I want to plot the data points with 0's and 1's separately as a histogram. This wasn't that hard to do: insert -> charts -> insert statistics charts and select the relevant data and I'm done. The charts are:

The orange plot corresponds to the first distribution (indexed by 0), and the blue one corresponds to the second (indexed by 1). The problem: I want to combine the two into a single chart with two differently-coloured bars. However I can't figure out how to do it. The obvious way is to right click -> select data -> add both data series to the chart, but the histogram still shows only one set of data. The data is definitely there - if I change chart types the other series shows up - but it doesn't show up in the histogram.

How can I do this with Excel? If Excel is unable to do this: what program would be able to do it? If it matters, I'm using Excel 2016.
