Hi,
I would recommend doing a bar graph for your data. For each sample, you would have one bar for the control results and one for each dilution:
Here is a site that will help you make a bar graph.

Here is the information from the Science Buddies website on presenting your data.

It would be great to record the production of gas as a function of time and do a line graph but I think the bar graph would be a clearer way to present your data.
