Hej,

Jag loggar lite grejer.
Se http://eservice.no-ip.org:85/temps/ener ... end=energi
Jag vill skriva ut fler tider. Mån 00:00 till Mån 06:00 som ett exempel är väldigt lång tidsspann. Jag vill ha fler tidsangivelser i grafen.

Är ni med på hur jag menar? Det verkar inte spela någon roll om jag gör grafen bredare. Den är redan väldigt bred.

X-Grid

[-x|--x-grid GTM:GST:MTM:MST:LTM:LST:LPR:LFM]

[-x|--x-grid none]

The x-axis label is quite complex to configure. If you don't have very special needs it is probably best to rely on the autoconfiguration to get this right. You can specify the string none to suppress the grid and labels altogether.

The grid is defined by specifying a certain amount of time in the ?TM positions. You can choose from SECOND, MINUTE, HOUR, DAY, WEEK, MONTH or YEAR. Then you define how many of these should pass between each line or label. This pair (?TM:?ST) needs to be specified for the base grid (G??), the major grid (M??) and the labels (L??). For the labels you also must define a precision in LPR and a strftime format string in LFM. LPR defines where each label will be placed. If it is zero, the label will be placed right under the corresponding line (useful for hours, dates etcetera). If you specify a number of seconds here the label is centered on this interval (useful for Monday, January etcetera).

--x-grid MINUTE:10:HOUR:1:HOUR:4:0:%X

This places grid lines every 10 minutes, major grid lines every hour, and labels every 4 hours. The labels are placed under the major grid lines as they specify exactly that time.

--x-grid HOUR:8:DAY:1:DAY:1:0:%A

This places grid lines every 8 hours, major grid lines and labels each day. The labels are placed exactly between two major grid lines as they specify the complete day and not just midnight.
