Legend problem with one data point 2069 2
Started by Deleted User
If I do a plot with only one point, then that dataset won't show up in the legend. In the following the p1 plot will show the point, but it won't show up in the legend, only 3 grey dots and the 'A' will show. Do anyone know if it is just an IDL bug or if I am doing something wrong
Thanks

Limit to Shapefiles 2247 1

A customer has posed the following question:
Error is Assertion failed!Programs:....File: shpopen.cLine 928Expression: psObject -> nSHPType==psSHP -> nShapeType ||psObject->nSHPType==SHPT_NULL
I am reading in shapefiles (they are large ssurgo soils for US states) and writing out a new shapefile with a subsample of the shapes,
the code works great for smaller states, but fails when there are say over ~1 million shapes. Is there a size limit and if so can you remove the size limit

Old program not working on new system 2319 1
Started by Deleted User
An IDL user has asked the following question:
I upgraded to 8.5 earlier this year (License ID: 5500131) as I am now running OS X Yosemite (10.10) and a data processing program I used previously not longer works. This is an old program (circa early 2000s) that reads binary data files from an older satellite and produces a save set of the data. When I use the program in the present idl version, the data it produces is garbage. It appears to be a problem with reading the binary file.

Hi, I'm brand new to IDL but I've been banging my head off this all day: I'm reading in a set of 55 structures from fits files and I'd like to consolidate them into a single structure that I can call without having to redo the read in every time. Unfortunately IDL's need to define everything prior to use has made it rather more difficult than other programs to do this.
The code below is roughly what I would like to do. (Although obviously it doesn't work like this)
