Cloud base Graph

[K8POS]

Not sure if I should direct this one to Steve or Mark.
I am using the SS Gauges in my web pages, when you hover over the cloud base gauge, a graph pops up giving the cloud base, but the scale shows Pressure, not feet/meters.
Also notice that this graph is not shown in the trends page of graphs.

Quite correct. That is what it shows. And there is no trends graph for Cloud base.

[mcrossley]

Correct, no cloud base graph in Cumulus, so you can either remove the graph altogether, or create your own as I have with jpgraphs in PHP, but that does require you to log your real time data.

But it's possible to make one

Laurent is this produced as part of Mark's JSON MX Graphs because I cannot see it in the source files, or did you produce it using Mark's code as a base?

[laulau]

Hi Mark,
I guess it's possible to get the data to feed jpgraphs with realtimeLogSql.php script ?

Guess how I do mine I don't have MX uploading the json files, just my tag files, so yes I just query my real time MySQL table.

It's based on Mark's code but the data are extracted from my SQL table !

[water01]

Care to share?

All my 'mx' graphs come from a MySQL dB too, I had to adapt the MySQL code to use the MX JSON files. The only real change is in graphSettings.php to the get_data() function to query the dB rather than reformat the MX JSON data.

You can then create whatever graph you want - I also separate out the UV from Solar.

realtimeLogSql.php based on Mark's code :

Code: Select all

<?php
//-----------------------------------------------------------------
// Query a Cumulus realtime MySQL table and return the requested fields
// along with the time stamps in a JSON format suitable for use with
// the Highcharts graphing package.
// Author: Mark Crossley
//
// Version 0.2 - 18 Dec 2012
//
// Call this script as e.g. ...
//         realtimeLogSql.php?recordAge=NNN&recordUnit=XXX&nth=NNN&temp&press
//         realtimeLogSql.php?recordAge=6&recordUnit=hour&nth=5&temp&press
//  Where:
//    recordAge=NNN
//		Returns records newer than NNN recordUnits, 6 hours in this example
//    recordUnit=XXX
//		The units to use for recordAge (second,minute,hour,day,week,month,quarter,year)
//    nth=NNN [OPTIONAL parameter]
//		If supplied the script will only return every n'th row from the realtime table, otherwise all
//      rows within the time range are returned. Useful for reducing large data sets for presentation.
//      This example will return every 5th row from the table
//    &temp&press
//		Returns the temperature and pressure data - concatenate as many record types as you wish.
//
//  The data arrays are returned in an object with the key name equal to
//  the param name supplied in the URL. In the example above the returned
//  object will be: {"temp": [[t0,v0],[t1,v1],...],
//                   "press": [[t0,v0],[t1,v1],...]}

Just when I thought it was going to be easy!

[mcrossley]

I'll post a SQL version in the MX forum soon...

[OliII]

Hi ! I'll be interessed too for these graphs. But, i don't have access to the mxforum. Could you post these here ?
Thx.
