Cannot plot all data in a stacked bar chart?

Question

I try to plot a horizontal stacked bar chart, with elevation as the y axis, and Europe and North America (data) stacked along the x-axis with the following code. Not sure what's wrong. Not all data are shown and the width of the bar is too thin to look at.

fig, ax = plt.subplots()
ax.barh(EleRegion['Elevation'], EleRegion['Europe'], label = 'Europe')
ax.barh(EleRegion['Elevation'], EleRegion['North America'], label ='North America' )

The dataset is below:
