INDIGOplotD -- a plot tool for indigo

Devildog0331 · Post by **Devildog0331** » Fri Jun 20, 2014 3:19 pm

Just an update... I blew all the old INDIGOplotD and SQL Logger settings out (pref files and all).. I even completely removed Indigo and reinstalled it.
I set up SQL Logger to use SQLite then installed version 2.6.1 of your plugin (even ran the install script for GNUPlot). Everything installed and configured without a hitch and I'm generating some plots Also... the plugin is running in Batch mode and plotting in MatPlot.

When you're ready to do some testing, I'll backup my files and we can figure it out. For now... my log is free of red text!!!

Enjoy the game!

I found a convoluted problem, need to ask Matt

if I do

self.pluginPrefs["sqlLastID"] = "xxx"

in the config menu and then (after the statement in Configuration) in the runConcurrentThread (thats the endless loop that waits for anything to happen, I get 2 different results.

https://www.dropbox.com/s/nzcb1lrknwhej ... 03-0-7.zip V 3-0-7

fixes:
1. MATPLOT picture size was sometimes too small.Its now the same size as GNUplot ( used integer to divide instead of float)
2. range went to automatic when the range had less than 4 characters i.e.: range = 3:9 was ignored, now the range is set correctly to low limit (X, or rightY or leftY) = 3 and high limit =9
3. a convoluted timing problem when data was written to indigo and when read back it was not properly refreshed when reading it - data stays sometimes several minutes old.
INDIGOplotD now circumvents that situation. This was leading to bad indexes and crashes.

added:
Single dots see attached plots. the same data is plotted many times, just shifted down with different DOT and LINE types and colors..

Not tested:
POSTGRE sql database.

https://www.dropbox.com/s/uv76diidjipus ... -3-1-0.zip Version 3.1.0

fixes:
-SQL import went into loop when a state of a device was used twice, i.e. as average and as max temperature.

NEW:

INDIGOplotD now has an INDIGO python interface.

version 3.1 has add the option to set or change (most) parameters from python code
here the function / methods available:

#first get the plugin object
plug = indigo.server.getPlugin("com.karlwachs.INDIGOplotD")

# here the calls:
plug.executeAction("addDeviceAndStateToSelectionList", props = dev123)
# this will make device / states available to be plotted, as soon as ta device/state is defined INDIGOplotD will start tracking its data
# it does the functions of the configuration menue

plug.executeAction("createOrModifyPlot", props =Plot123)
# this will create a plot, set size, background color scales etc.
# it is the the starting page of the plot device setup

plug.executeAction("createOrModifyLine", props =Line123)
# this will create the lines in the plot, select which avialble dat to plot, set color of line, width, dashed, solid dots etc.
# it is the function of the last part of the plot device configuration menue

plug.executeAction("createPlotPNG", props ={"deviceNameOfPlot": nameOfPlot})
# this will tell indigo to immediately create the PNG files for the requested PLOT, INDIGOplotD will recreate the PNG files every 5 minutes.

plug.executeAction("createAndShowPlotPNG", props ={"deviceNameOfPlot": nameOfPlot})
# this will tell indigo to immediately create the PNG files for the requested PLOT AND display them on the server monitor

#and to delete devices / plots /lines use:
plug.executeAction("deleteDeviceAndStateFromSelectionList", props = dev123)
plug.executeAction("deletePlot", props ={"deviceNameOfPlot" : nameOfPlot })
plug.executeAction("deleteLine", props ={"deviceNameOfPlot" : nameOfPlot , "lineNumber" :"1" })

Each function will set INDIGO variable: "INDIGOplotD-Script-Message" with a return code, you can check it in your python script
-"ok: and some text" is a positive result.
-"error: and some error info" indicates a failure, only the last message will be shown

Here the definitions of the props:

example of a complete code to do a thermostat plot (name of thermostat device is ThermostatDownstairs):

just copy and past into a action group/device serveraction / script and replace
- ThermostatDownstairs with the name of your thermostat
- nameOfPlot ="DownstairsPlot"
with your names.

Code: Select all

deviceName="ThermostatDownstairs"  # <======= change this

plug.executeAction("createAndShowPlotPNG", props ={"deviceNameOfPlot":devname})

the 2 example codes will produce the attached plots.

I have tested a number of scenarios, but there are likely still some combinations that will create error. Anyway hope its useful

Thanks for this great plugin. Got off to an easy and good start. I did run into a couple snags:

1) Same as mat from the previous thread, if I try to use gnuplot, it tells me that it's not configured correctly for fonts, and plots do not generate. I do have gnuplot installed, and can type 'gnuplot' in terminal to launch it. I can even manually run gnuplot from the terminal, referencing one of the indigoplotd .gnu files, and it creates the plot. But no matter what I do, if I have gnuplot selected in the indigoplotd configuration, it will not update the plots. If memory serves, I installed gnuplot with macports when I had 10.8 on the indigo machine. It is in /opt/local/bin, and I have been using it for a while through script files to produce the plots I need for my control pages. It's been working fine, even selecting different fonts. I'm currently running 10.9.4 on the indigo server.

I was fixated on gnuplot, because I want a transparent background on my plots, and know how to do that in gnuplot. I added the 'set term png transparent truecolor' raw command in expert mode, which did appear in the .gnu files created by the plugin, and when I manually plotted one of those, it did produce a transparent background. Since the plugin is not working with gnuplot, however, I'm not getting plots.

So 2) I switched indigoplotd to use matplot instead of gnuplot. The plots started updating immediately, and appear to be working correctly. However, I don't know how to get a transparent background with matplot. I have read that when you are saving the image, you can use a 'transparent=true' switch, but I can't tell that I can enter that anywhere with the plugin.

Thanks for any insight you can provide on getting a transparent background with matplot.

transparent has been on my to do list.. will check into it..

as for gnuplot refusing to start, it tries to use fancy fonts, if it does not work it thinks gnu plot is not installed.

the supplied gnu plot install is enabling the fancy fonts look at the bottom of the help.pdf if you want to install gnu plot manually with fonts.

Karl

gtreece · Post by **gtreece** » Sat Jul 05, 2014 4:29 pm

If by fancy fonts, you mean the ability to use ttf font faces, I can do that from the command line in gnuplot. My current scripts utilize ttf fonts because I didn't like the appearance of the default system fonts when I first installed it.

How does the plugin check for fancy font support? Maybe that will help? I remember some bits and pieces from the install, centered around where GD looked for fonts when you installed gnuplot through macports. Too long ago to remember details, but I think I either had to specify full paths to font files, or change an environment path variable or something.

Since gnuplot is already installed and working through my scripts, I'd prefer not to re-install it, and also add brew to the mix. I can always keep doing charts the way I have been if I can't figure it out in the plugin.

kw123 · Post by **kw123** » Sat Jul 05, 2014 4:32 pm

do you want to have the background transparent or the "filled blocks/ histograms?"

I tried the transparent lines (truecolor etc) , and the plots do not look different...
how do you know that the background is transparent.. do you have to insert in to another document??

gtreece · Post by **gtreece** » Sat Jul 05, 2014 4:48 pm

If I open a png in Preview, I get a kind of gray background color, rather than white. The Finder quick preview still shows it white, so have to open it to be sure. I will try to attach a screen grab of what I see when I open a plot image in Preview. I lay the png images on top of other elements in my control pages, so I need the background to be transparent. When I run my scripts, I do that with this:

'set term png transparent truecolor'

transparent only works with truecolor, so you have to specify it for the transparency to work.

I did test this with your plugin, by putting the above in the raw gnuplot command field. I verified that the generated .gnu file contained it, and then fed it to gnuplot manually in terminal. It generated the plot correctly, including a transparent background.

So it's just that for whatever reason, your plugin can not detect that my gnuplot install is fully functional.

kw123 · Post by **kw123** » Sat Jul 05, 2014 5:06 pm

i have the transparent working in gnu plot. But when inserted e.g. into a word doc it becomes white!

will include the option into the PLOT menu. will take me a day. will also do it for matplot

as for gnu plot not being recognized: will look into the code this evening..

Karl

gtreece · Post by **gtreece** » Sat Jul 05, 2014 5:08 pm

Great news! Thanks!

Also, I have not tested it, but I believe that transparency capability was added to linecolor at some point, with the following syntax:

lc rgb "#AARRGGBB"

Where AA is the alpha or transparency channel. So 'lc rgb "#77000000" would produce a transparent black line.

With fills, I believe transparency is handled with a style, like:

'set style fill transparent solid 0.5'

You would still need to have a terminal type set that supports transparency. I have only ever seen the fill transparency on filled curves. I don't know if it works on all fills or not.

I just did a quick test, and manually edited one of your .gnu files produced by the plugin. I added a transparent condition to one of the fillsteps:

using 1:((($13)*(5.0)+(0.0)) ) with fillsteps fill transparent solid 0.5 linewidth 1 linecolor rgb "#0000A0" title "AC On" axis x1y2\

And it worked great, to make the fill transparent. I also tested by adding a set style:

set style fill transparent solid 0.5

and that worked as well, leaving the fillsteps to it's original syntax. The fill style took over.

Lines do not appear to be as simple. It appears to depend on terminal type, as to whether or not the rgb"#AARRGGBB" format works. It doe snot appear to work for the png terminal type.

got the transparency ...

as for gnuplot not working... could you post the exact error message with fonts .. ?

here the code that test fonts . but it does not stop. its just a warning that true type fonts are not available

Code: Select all

	########################################
	def testFonts(self):
		try:
			f= open( self.indigoPlotDataDir+"temp/test.gnu" , "w")
			f.write('set terminal png enhanced medium  font "/Library/Fonts/Arial Unicode.ttf" 12   size 800,350 dashlength 0.5 \n')
			f.close()
		except:
			self.logMessage(u"fatal error, can not create files in indigoplot directory, stopping ",0 )
			self.quitNOW =True
			return
		if self.gnuORmat =="mat": return  # no more if we do matplot
		
		ret=subprocess.Popen("'/usr/local/bin/gnuplot' "+  self.indigoPlotDataDir+"temp/test.gnu",shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE).communicate()[1]
		if len(ret) > 10:
			self.logMessage(' gnuplot is not installed with proper font support, please select option "(re)INSTALL gnuplot.. or TrueTypeFonts will not be available"',1 )

		try:
			os.remove(self.indigoPlotDataDir+"temp/test.gnu")  # and clean up
		except:
			end

If I change from matplot to gnuplot, I get a message that gnuplot is not installed and check the readme. If I then reload the plugin, I get that error message again, as well as the not installed with proper fonts message:

INDIGOplotD Error ------------------------------------
INDIGOplotD Error gnuplot not installed please check readme file for how to install gnuplot
INDIGOplotD Error ------------------------------------
INDIGOplotD gnuplot is not installed with proper font support, please select option "(re)INSTALL gnuplot.. or TrueTypeFonts will not be available"
INDIGOplotD initializing ...2

That is the only error message I've seen, but the plots stop generating as soon as I do that.

I can open terminal, launch gnuplot, and paste in the set term command you use, and it works fine. What I notice, however, is that you are specifying a full path for gnuplot, /usr/local/bin/gnuplot, that is not where my gnuplot is. Mine is at /opt/local/bin, which is where macports puts stuff I think:

hac:local user$ which gnuplot
/opt/local/bin/gnuplot

I should be able to make a link for it in that location, so that /usr/local/bin/gnuplot would be valid. I'll give that a shot.
