I’m reading a MySQL database where a table has bid, ask, price_datetime (where price_datetime is down to the second). I’m trying to get 2 line graphs going where the X axis is the price_datetime column and the first line is bid and second is ask.
I can’t seem to get this working. I’ve seen ZedGraph – I am looking for an example of using a DateTime but it didn’t work for me. The example page no longer exists.
Any ideas?
The answer should be as in the question you link to. You must convert to XDate before plotting – and of course the axes should be configured to be a Date axis.
I see a lot of the ZedGraph website has 404 errors, but there seems to be a nice tutorial on codeproject. About half way down the page there is a Date-time axis example.
