I simply want to create a chart with numbers on the y-axis and times on the x-axis.
I'm using these blocks to insert entries into the chart ...
... so the x-values are numbers of millis (that's the simplest way for me to compute the values I want) and the y-values are numbers from a html get request since over wifi.
Everything looks good, except I'd like the x-axis time values to be formatted at HH:MM instead of HH:MM:SS.
... but I'd prefer the time was just HH:MM
I tried this ...
...but if flags "invalid chart entries".
Proviidng a list of two-element lists does not work, because the x-labels are not spaced correctly (i.e. 10:15 and 10:30 are closer together than 10:45 and 11:00).
Use the chart Labels property to hold your list of HH:MM time stamps, and add your x,y values starting with x=0 and adding 1 to x for each minute.
I assume your data is spaced one minute apart?
For sample code, upload sample data.
That looks like it will work, thanks. Just have to work out how to generate the labels. Data is 15 minutes apart.
