Description
Welcome to 'mm Graph Pro', the full-featured version of the 'mm Graph' android app. The app will help you to draw graphs and perform curve-fitting and analysis of multiple sets of X-Y data on a millimeter-division graph paper very easily.
As in 'mm Graph', you may get step-by-step help in marking data points on a mm-division graph paper.
With the Pro version, however, you may additionally:
* Draw your graph anywhere on the mm-division graph-paper by shifting the origin, by changing the axes-margins etc.
*Perform custom grid-scaling i.e. change the values corresponding to the smallest scale (1 mm) divisions along the X and Y axes.
*Import data already saved in files in your device into your app in different formats and different layouts. You may also edit the imported data before plotting.
*Make use of an embedded clock and stop-watch to take data readings which require a timer.
*Plot up to five sets of data on the same graph, for e.g., five sets of drain-current versus drain-to-source voltage for different gate-to-source voltages in a JFET transistor.
*Plot as many data points as you wish.
*Orient the graph paper vertically or horizontally for an optimum plot.
*Even after a graph is drawn, you may edit X-Y values for a data point or delete a data point from the graph and re-plot.
*Modify the X and Y axis variables, for e.g., change X to log(X), Y to 1/Y etc.
*Fit your data to all the common fitting functions and even to any arbitrary user defined function.
*Interpolate your data using Linear, Lagrange or Cubic-spline interpolation.
*Find X at any Y or Y at any X from the fitted or interpolated curves for one or more sets.
*Perform a slope calculation at any point on the fitted curves, just as you would do on an actual mm-division graph paper using a scale and a pencil in the laboratory.
*Insert text and arrow annotations on your graph to highlight important facets.
*Record the details of your lab-assignment related to the plotted graph.
*Save the full-sized e-graph (which exactly mimics an actual mm-division graph paper) with the plotted data into your mobile device.
*Also save the X-Y data set(s) to your device in different formats like .dat, .csv, .txt etc so that you may plot them later with your 'mm Graph Pro' app or any other graphing software if you so wish.
*Share your saved data and image files with your teacher, classmates, friends or anybody through WhatsApp or email from right inside the app.
*Get answers to 'Frequently asked questions'
In short, do everything you need to do with your mm-division graph paper in the laboratory or outside, using just your mobile phone or tablet.
And more ....
While students of all ages and disciplines are bound to find the app helpful, teachers too would find the app useful when checking graphs drawn by students with custom origins, custom graph-axes lengths and custom graph scales.

😂 I have explored quite some features offered in your app. This is simply unique and outstanding app. It really deserves, let's say, some award (maybe from Google). Highly accurate and very useful. Please continue with the project and keep updating. Thanks. 😁
