Graph showing daily data for two different years

Welcome to the Forum!

I would need to see how you have organized your data. This is a very straightforward problem if the data is organized properly.

It will be much easier to understand your problem if you provide your file. This allows us to see your data, layout, much easier than describing it in several paragraphs. To post a file:

1. Under the text box where you type your reply click the Go Advanced button.
2. In the next screen look above the reply box and click the "paper clip" icon. You will get a pop-up screen.
3. In the pop-up, click Add then Select to select a file from your local drive
4. Click the Upload button to upload the file
5. Click Done to attach it.

It will be displayed as an attachment underneath your post text. Alternatively as the last step you can click the Insert Inline button and a hyperlink to the file will be inserted directly into your post text in the spot where your cursor is set at the moment you click the button.
