GidPlot 0.2.2

Added

• Add prompt when exiting app, if there are plot/CSV tabs/windows open.
• Add additional separator options: tab, space and semicolon.
• Add option to combine contiguous separators.
• Auto-detect separators.

Changed

• Improve handling of missing/unexpected columns.
• When a row has more columns than previous rows, add a new column and back
  fill data in previous rows, and indicate errors.
• When data conversion or no data errors are detected (i.e. insufficient columns),
  show the used value in the table and not a question mark. Show the original
  value (if applicable) in the error message (table cell tooltip).
• Improve error messages in table cell tooltips.
• CSV import: Trim spaces off headings text, as well as individual headings.
• Increase number of lines in CSV import dialog preview from 10 to 100 and
  indicate at the bottom when the file is only partially shown.

Fixed

• Fix crash when trying to plot a column for which there is no data.
• Guard against crashes when data does not exist when plotting.
• Force map plot crosshair lines and text to black so it doesn't turn out
  white in system dark themes.
• CSV import: when headings text box is empty, do not use a blank string
  for first heading.

GidPlot 0.2.1

This is not an April fools joke.

Added

• Measure from existing markers.
• Option to open an empty map.

Changed

• Improve map performance with large data sets. All track lines are now drawn
  in one single map object, saving overhead as opposed to using a separate
  drawing object for each track line segment.
• Improve map performance when data set contains repeated coordinates, by not
  plotting track segments with zero length.
• Improve legend auto-show logic. Never show when no curves are present.
  By default for new plots, auto-show is on, meaning legend is hidden when
  there is only one curve, and shown when there is more than one curve. If the
  user changes the legend visibility, auto-show is disabled.

Fixed

• When copying marker, take range start into account so index is correctly
  transferred to other plots when pasting.
• Fix issue on Windows where annotation marker blocked the mouse from clicking
  on the map while creating a measure, preventing map panning or ending the
  measure with a click.
• Properly hide mouse crosshairs by default on a new map plot.
• Allow placing marker at mouse if there are no graphs on the plot or map.

GidPlot 0.2.0

Added

• Map plot legend.
• Markers on map plot.
• Measure on map plot, including distance and heading calculations.
• Marker copy and pasting on other plots. Marker text is also copied to OS clipboard.
• Copy marker coordinate to OS clipboard (from marker context menu).
• Add marker at mouse position.
• Copy submenu in plot context menu to copy coordinates and index to OS clipboard.

Changed

• Map plot crosshair now shows index too (similar to normal plots).
• Plot context menu now has submenu for markers (adding, pasting).
• New plot properties icon in plot context menu.

Added

• Plotting latitude/longitude data on a map! An actual map! Map tiles are

  smarter algorithm which is faster - especially noticeable for large data
  sets.

• Add range name to plot name (i.e. as shown in legend) if the range is not
  the full data range.
• When saving as image, use plot title as default filename.

Fixed
