CHEMIX School 8.00  (released 2020-5-21)
New v8.00 YouTube video Tutorials


Added a Data Logger (Curve Fit - Function Plot - Data Logger) :   In this CHEMIX School version, a serial port data logger has been added. The purpose of this new addition is
                                                                                                                to be able to acquire and view serial data collected from micro controllers such as Arduino.
                                                                                                              -  Added  Plot of  vertical lines XiYi to Xi(Yi=0)  to the Interpolation & Curve Fit  drop down list. Suited for visualization of data acquisitions from e.g. Geiger-counters.  
                                                                                                              -  Added Initialize to default button. --> All settings to startup conditions.
                                                                                                              -  MAX number data points has been increased from 400 to 1000 .

                                                                                                               -  Added Save as   *.CSV    (comma-separated values)
                                                                                                               -  It is now possible to see the total number of  XY pairs in a data set.
                                                                                                  Standard logging (default):  Receive X Y data
                                                                                                               1) Stops logging automatically after a selected number of data points (Max 1000pts).
                                                                                                               2)  Possibility to keep track of  up to 1000 of the Last log points . When a selected number (e.g. 1000 pts.) of logged
                                                                                                                    data points has been reached, (X,Y)-1 will be replaced by (X,Y)-2 and (X,Y)-2 will be replaced by (X,Y)-3
                                                                                                                     and so on . ( Replace old points after ### points)
                                                                                                    Each second the logger will read and present available serial data. If log-data is received, the data will be copied to the data-edit field
                                                                                                    and automatically plotted.
                                                                                                    NOTE: To receive a big list of XY data (limited to <= 1000 X Y pairs), use "Standard logging" (advanced logging unchecked) and
                                                                                                                  the logger will once a second read, collect and present as much data as possible dependent of the baud rate.

                         Logging will be stopped if     Y(i)    > =     c                                      
                                                                                                                                Stop if  Y(i)    < =     c
