What's New in UniPlot 5.7.0
===========================

This page describes the changes made to UniPlot 5.7.0 since version 5.6.3.

New Features
------------

* :ref:`the-data-browser`: A data preview of a selected data channel can
  be displayed. Choose :ref:`fileimport-data` and click on the **>>** button. 
  The preview diagram will display the data over the point index starting with 1.
  Missing values will not be displayed.

  .. image:: S:/uniplot-obj/images/dateneditor-menu-dlg.*

* :ref:`dataadd-magnifying-diagram`: This function can be used to magnify a
  visible part of a diagram in a separate diagram. The selected section (lens)
  can be moved and resized using the mouse or the arrow-keys. The magnifying
  diagram can be fixed to its position or moved with the selected section.

  .. image:: S:/uniplot-obj/images/MagnifyGlass.*

* :ref:`datacursor-data-table`: New command to create a table displaying the
  cursor data.

  .. image:: S:/uniplot-obj/images/CursorDataTable.*

* :ref:`edit-search-and-replace-ipw`: Searches for a string and replaces it
  with another in all open IPW documents.

*  A number of libraries have been updated (pcre, VTK, sqlite3, libxml2).

* A table of all new functions is found under :ref:`uniscript-5.x`.

* A table of all modified UniScript functions is found under
  :ref:`uniscript-5.x`. The changes can be found in the history table at the end
  of the function description.

Bug Fixes
---------

The following bugs have been fixed:

* (ID380): :ref:`uniplot_3dview`): The number of data points for the
  scatter plot was not limited. This could lead to a program crash if the 
  number of points was greater than approx. 5000 points. Now, only the first 
  5000 points will be displayed. The number of points for the 3D-curve has also 
  been limited to 1000 points.

* (ID1726): :ref:`XYFind`: The function did not return the data point with the
  index 1, if the data was sorted in decreasing order.

* (ID1731): :ref:`LayerSetAxisTitle`, :ref:`LayerGetAxisTitle`: The newline
  character has been changed from ``\r\n`` to ``\n`` to make the functions
  compatible with text objects (:ref:`TBGetText`) and table objects
  (:ref:`TableGetText`).

* (ID1732) :ref:`regex`, :ref:`regsplit`: The functions did not handle Unicode
  characters correctly and did not support the case-insensitive flag.

* (ID1733): :ref:`datadataset-list`: New buttons have been added to
  modify the dataset order in a diagram: "One Up", "One Down", "Send To Back",
  "Bring To Front".

* (ID1735): An error occurred, if a text file was opened with :ref:`SynEdCreate`
  and then opened again with :ref:`EdCreate`.

* (ID1736): The case of a file name of an existing text file was modified, if
  the name was specified with a different case. For example the call
  :ref:`SynEdCreate("TEST.TXT") <SynEdCreate>` would change the case of an
  existing file with the name "test.txt" to upper case.

* (ID1739): The :ref:`interpol` and :ref:`auto_xy_RemoveDoublePoints` function
  did not handle datasets with only one data point correctly.

* (ID1748): :ref:`datadata-exchange-(document)`, :ref:`datadata-exchange-(page)`:
  The option "Use Record Filter specified in Datasets (Curve)" was not used
  correctly for 3D-Datasets.

* (ID1749): :ref:`datainterpolation`: The option
  "Interpolation-Range-Automatically" has been added to the interpolation dialog 
  box.

* (ID1750): UTX-Import-Filter: UTX formatted Excel files could not
  be read if the header contained empty rows between the key words ``UXX-BEGIN``
  and ``UXX-END``. This error occurred only in UniPlot 5.6.3.
  See :ref:`utx-data-file-format-specification`.

* (ID1751): :ref:`FileToField`, :ref:`StringToField`: If an Unicode character
  width a value greater than 255 and a byte value of the lower byte matching the 
  value of the separator (59 for ;) was not handled correctly. This bug
  could occur during the import of UTX-Excel files.

* (ID1752): UTX-Import-Filter: UTX formatted Excel files could not be read if
  a cell contained a semicolon. See :ref:`utx-data-file-format-specification`.

* (ID1753): :ref:`map-calculator`: The INCA format string
  ``CALIBRATION VALUES V1.0;,;`` was incorrect, if the decimal symbol in the 
  Regional Options was set to ".".

* (ID1755): If the option "Do not keep history of recently opened documents"
  in the Group Policy Editor (Gpedit.MSC) was enabled, UniPlot terminated with a 
  memory access violation during startup.

* (ID1758): :ref:`TableDeleteColumn`:  If the column index was greater than or
  equal to the last column, a memory access violation occurred. For example, the 
  call ``TableDeleteColumn(hTable, 1000)`` did not remove the last column.
