I am new and have been reading and playing with the tutorials.? I have
not seen what I need to do.
I am collecting data on some machines every second. I collect
temperature, input voltage, and percentage of the time on. It is two
machines (for time on),? 4-8 temperatures, and 4 voltages.
it comes to me as a csv file or line, with Date, time, and then all the
values comma separated.
I can rearrange the data to however Matplotlib requires in Python. That
is not the issue.
I do not know how to plot the date/time x-axis.
The user wants to look at the past hour, past day, past week, past
month, and past year.
For the plot of the last hour I need a line and the time every 10
minutes on the x axis.
For the plot of the day, probably a vertical line every hour and a label
every 3 hours.
For the plot of the week, a line at midnight, and a day label between
For the plot of the month, I do not know what might work.
For the plot of the year, a line between the month and the month between
I want all the data (or a good portion of it) between the axis markers.
How do I do this, or find examples or documentation on how to work with
time and dates for the x-axis?
helped me a lot. I did not know about strpdate2num.? But I think I need
a date&time equivalent. Is there such a thing? Where would I find it? Or
do I have to make it?
I had a friend suggest going with MRTG because it produces the graphs
clost to what I want. That looked harder.
People log data by time and date and graph it all the time. Something
like this has got to have been done before.
