Data Visualisation: Graph for many different options

i need to visualize data. I have a list of options with 20 values from 10kg to 10t. They all should be shown in two different ways. One with the original values and one with the percentage. I thought about a bar graph and a pie chart. But with both i have the problem that i get very small parts for the small kg values. I've only a limited space to show the data. Does someone have an idea if there's any better way to show the data? Or has some examples with good solutions for this problem?

thanks in advance Simon
