Draw or Plot On Panel

xrmichael

Might be a odd question, but is there a way to mark a 2 sets of x,y cords then issue a command to draw a line between them ? sort of SEND_COMMAND dvtp,'20,20,30,30,draw' ? I want to plot out the clients power usage / temp over a period of time. I could also line up a load of levels but that would be a bit messy to do a years stats.

I have not tried this yet, but it seem to recall someone mentioning it elsewhere on the forums. Google has a chart api that lets you submit info via a url and it will create a chart image for you. You could use this with dynamic images to create an image file.

Here is a link:

Add a | character at the end of the path and use chart.png for the file name.

There might be a way but I don't know how elegant it would be. You can change the size and position of a button so by resizing/moving it you can make it look like drawing a line across the screen. I would think using levels would be far easier though.

I was looking for something like this as well so I could completely bypass an Aprilaire 8825 and still give the client a history graph (the only feature I haven't been able to replicate). Thanks for the heads-up on the Google chart, it might be just what I need. I was looking at all manner of html graphing solutions, and all of them were ugly.

Thanks

Cheers for the responses i will have a look at the google option, is there a limit on the number of levels for some reason i have 8 i my head but could be wrong.
