Now that version 4.5.1 is out the beta resets. There are features that are hidden in the release version but are visible in the beta so they can be tested and refined.
Live on the edge, follow the beta. It is fairly stable, but transient problems do pop up. They are quickly dealt with and the beta is occasionally updated daily. If you are running the beta you will be notified if a new version is available.
Existing Features in the Beta
Data File mechanism.
Can create this using R (still in early testing, contact me to get the R package)
or using the Special Import and the new Save button.
The Data File is created through the Other option and is a group.
R package (with source) to write data files is under testing,
let me know if you are interested in C++ source code to write data files
and if there is interest in a python library.
Working on making it easy to get data into DataGraph from various programming environments.
Units conversions for the standard numerical column type.
Create them through the gear menu.
A preference option so that you can set when the Points command switches to a pixel approach.
The default is 200,000 but you can raise it if you want to get more points drawn with the selected marker.
Scalar Field command - recently added an option to draw logically rectangular meshes.
This means you can specify the x and y coordinates of the mesh as arrays and not just lists.
Column - Number From String - Looking for a good use case
Beta Release Notes
2/17 : 4.5.1 is being submitted, resetting the beta
3/4 : Fixed an issue with the context menu for a Plot command (selecting columns)
3/4 : Fixed an issue with the the smooth option for the Box Command.
3/17 : Tweaked some things to work better with the R package.
3/17 : If you use a Legend for a points/plot/fit command where the legend name is the same but masks differ, the commands will now show up as different legend entries.
Before they were overlain and showed as one entry in the legend.
Now, it will be overlaid only if the x and y columns are the same and the masks agree.
3/24 : Fixed an issue with line join and animations.
3/27 : Sped up the Plot Action command.
3/30 : Fixed a problem with the Plot Action that was introduced during the last update.
3/31 : Fixed an issue when you copy-paste a group of drawing commands.
4/8 : Added a locking mechanism for columns and variables - use the Gear menu.
4/11 : Improved the locking mechanism.
4/12 : Fixed an issue with the JSON mechanism
4/12 : More locking issues.
4/22 : Fixed an issue with the JSON URL query.
4/26 : Fixed an issue with overlapping points.
4/28 : Fixed an issue with overlapping points when you had two or three points
(new method was initially > 3).
4/30 : Fixed a fill issue when using patterned textured fills.
5/23 : Graph group mechanism
5/27 : The slider variable can now use variables in the range. This also applies to the range for the animation slider.
6/19 : Released the graph group mechanism
6/19 : Improved support for reading the output from the R package.
6/27 : Rounded rectangles on 10.13 are now handled better.
6/27 : Added a gear entry to the graph thumbnail to export a figure and to copy it.
This means that you don't have to make it the active graph to export/copy the figure.
6/30 : Fixed issues with the scalar field and date columns.
6/30 : The pivot command didn't report the type properly for date columns for the flattened row/column.
7/1 : Improved netCDF import to deal with multidimensional arrays (2 and 3) -
See help request.
7/11 : Fixed a redraw issue when you opened a file where nothing was drawn.
7/11 : Tweaked how undo saves data to disk when memory gets tight.
7/21 : Fixed an issue with the graph thumbnails related to the group mechanism.
7/21 : The graph selector inside the Graphics command to reflect the graph groups.
7/21 : Can now drag a graph from the thumbnail list onto a graphic command to select that graph.
7/21 : Added a method to the variable to compute the sum of squares from a column.
Both the From Column and Expression variables.
