NeXpy v0.13.3 has just been released, and the underlying nexusformat API has been updated to v0.6.1. It is available on PyPI and conda-forge. Both packages require Python v3.6 or later. It fixes issues caused by the recent release of Matplotlib v3.4.0 and adds
support for new features in LMfit v1.0.2.

</div>
<div class=""> $ pip install -U nexpy</div>

Changes from 0.13.2
<div class="">----------------------------<br class="">
<div class="">
<div class="">• Adds a pull-down menu to the Projection Tab for selecting which panel to open (Projection, Limits, or Scan).<br class="">
</div>
<div class="">• Adds support for LMfit forms, which allow some fitting models to be customized. This requires LMfit v1.0.2.<br class="">
</div>
<div class="">• Confines the fitting range to the x-limits of the parent plot. This can be changed with the "Reset Limits" button.<br class="">
</div>
<div class="">• Removes legacy fitting functions that duplicate LMfit models.<br class="">
</div>
<div class="">• Makes the Script menu display subdirectories hierarchically.<br class="">
</div>
<div class="">• Adds new Matplotlib color maps - two qualitative maps (tab10 and tab20) and a gray-scale divergent map (divgray).<br class="">
</div>
<div class="">• Fixes issues caused by changes in Matplotlib v3.4.0.<br class="">
</div>
<div class="">• Fixes a plotting bug when a scan variable is not set in the Scan Panel.</div>

<div class="">Introduction to NeXpy</div>
<div class="">-----------------------------</div>
<div class="">NeXpy provides a high-level Python interface to NeXus data, within a simple GUI that combines a tree view of loaded files, Matplotlib panes to visualize multidimensional arrays, and an IPython shell for manipulating the data and metadata. NeXpy
is intended to be a simple, intuitive, interactive toolbox that allows users to explore ways of modeling NeXus data, with minimal overhead, and to create new NeXus-conforming data files without expert knowledge of the file format. NeXpy makes it easy to view
arbitrary 1D and 2D slices and projections of multi-dimensional data and to compare plots of multiple datasets.<br class="">
<br class="">
A built-in script editor allows new data analysis methods to be developed, tested, and refined. The underlying Python API for reading and writing NeXus files is provided by the nexusformat package, which utilizes h5py. NeXpy also contains a GUI interface to
the lmfit module for fitting 1D data. </div>

NeXpy is available on both the Python Package Index server and Anaconda, using<br class="">
<br class="">
$ pip install nexpy<br class="">
<br class="">
or <br class="">
<br class="">
$ conda install -c conda-forge nexpy<br class="">
<br class="">
