Saving PNG files through SSH connection to make movies 1875 1
Started by Deleted User
I do a lot of work remotely and am currently creating a cgPlot and then writing to a png file, saving a series of pngs to create a movie. But when I do this it can take 20 seconds or so to save 1 png, while if I do this on campus then it only takes 0.5 seconds to save the plot as a png.
Is there another and/or more efficient of being able to plot and save the plot as a png when connected remotely through a SSH connection

Plot Functions: How to save correctly plus placement of plot 1850 1
Started by Deleted User
Hey,
example:
p = plot(findgen(9), xtitle='x test', ytitle='y test', title='Test Plot')
p.save, 'testsave.eps', Resolution=600
The saved graph is not centered, but shifted to the right edge of the paper. I had the problem with some plots, that the far end of the x axis gets cut off. How can I change my code to center the plot Another problem regarding the centering,is that the plot is centered around the graph region and not around the plot region. So if I use epstopdf for latex it will create ...

Saving .ps files using plot function 1833 1
Started by Deleted User
Hello,
I'm trying to save plots to a multi-page post-script file. I previously used the plot procedure along with SET_PLOT and DEVICE to create my multi-page post-script file, and am now using the plot function and having no luck. Is there a way to use SET_PLOT and DEVICE while using the plot function, or do I have to instead save individual plots using p.save
Thanks for the help!
Best, Laura DeGrot

Persistent Error "Procedure header must appear first and only once: " 5562 8
Started by Deleted User
I've inherited code from someone, but I am unable to get it to run. I've searched other instances of this error, but they were related to calling functions, which I don't do. The idea is to take a series of frames from a video and add them all together. The frames are in grayscale. I have a for loop, which I end with endfor, and then I create the image and save it.
If you have an suggestions or ideas, please let me know. I can't find any documentation on this error, so I have no idea how to go a...

Calculating Class statistics for batch files 1584 4
Started by Deleted User
Hello,
I have a question about calculating class statistics. My current code performs an unsupervised classification on a batch of 25 images. I would now like to add the ability to calculate class statistics for the outputs but have so far been unsuccessful in getting this additional step to run. I believe I need to add another foreach command but am not sure how to pull my new classified images back in without having to somehow list them as I have for the initial batchfiles.

Secure OPeNDAP 1964 1

I am attempting to read in some CMIP5 model data from an OPeNDAP site that is protected by OpenID (https://pcmdi.llnl.gov/projects/esgf-llnl/).

Unpredictable text behaviour while mapping 1719 1
Started by Deleted User
I have run into a problem while making maps with many symbols on them. The included code runs fine for a few time steps but then will start to produce maps like the attached with all text blacked out. It appears to be somewhat random. I've broken the code into small pieces to try and debug the possible reason, but so far I have not found it. Any insight would be much appreciated.

ERRORBAR_THICK not working 1876 0
Started by Deleted User
I have encountered the error message " PLOT: Unknown property: ERRORBAR_THICK", when I was trying to control the size of my errorbar thickness.
I was seaching the forum for answers but found none. Now I have discovered that ERRORBAR_LINESTYLE and ERRORBAR_THICK are new features in 8.4, and I only have 8.3.
So here is the information if anyone at a future point is searching the forum with the same problem as I had.

i am using idl for the first time. My question is:
If one starts "demo" in idl (within the terminal/console), there are some examples. Under the directory "math and statistics" -> "math and statistics demo", there is an example for a polynomial fit.
Where is the source code for this polynomial fit within idl
