Update notes


9/13/2017 6.1.2
-Implemented a function to show a remark line in the data file as the data names on the "Data selector" window shown by [Data]-[Select Data], [Data]-[Read Multifiles] and so on.
-Added the option "0th" on the "Make equal interval table" window shown by pressing the "make table" button on the "Convert data" window shown by [Analyze]-[Convert Data]. The "0th" means just averaging the y-axis data".
-Fixed some items are shown in English even when the "Japanese" is selected as the language.
8/28/2017 6.1.1
-Added the option "apply to all" to change the label-font settings (default font, sub-font and their sizes) on the "Edit label" window.
-Added an option to choose the circle size "0" in the drop-down list on the "density" tab on the "Data selector" window shown by [Data]-[Select Column].
-Fixed a bug that the plot range for px, py and pz-axes is not considered in making a 2D plot.
Caution!! If your data disappear in the graph that you created by an older version of yoshinoGRAPH, refresh the plot range by the "full ragne" button on the "Input plot range" window shown by [Analyze]-[Plot Range].
6/21/2017 6.1.0

6/8/2012 3.1.11
-Fixed a serious bug that yoshinoGRAPH sometimes crashes when one closes the "Data selector" window shown by [Data]-[Select Column] after copying the graph window by [Window]-[Duplicate]. This happens the number of data in the graph window is decreased by, for example, differenciating data. If you created a project file by an older version of yoshinoGRAPH in this way, export corresponding data to one or more text files by [Data]-[Export] and make a new graph from the text data, please.
