0 Replies and 1324 Views netcdf attribute read  1324  0 Started by  Deleted User Hi, I'm trying to read the attributes from a netcdf file, that based on ncdump, are equal to: units = "10^-9 V/V air" when reading via ncdf_attget, instead of having it into type string, IDL thinks it's a number and converts it into a byte array. How can I force ncdf_attget to read a string, no matter what the data of the attribute is Thanks!

0 Replies and 1409 Views dual iTool interfaces without creating a new widget interface  1409  0 Started by  Deleted User I'm fairly new to IDL GUI design. I was wondering if there is an easy way to extend the iTool system to have all on the same window: 1. a typical iSurface plot 2. a typical iPlot plot 3. custom buttons From reading the IDL help, it seems adding the buttons in a user interface panel to an iSurface window, say, would be easy (like example4tool,example4_panel). It's adding a second iTool below the iSurface, the iPlot, that I'm wondering if would be a simple addition, or if I would have ...
